“Space and art, as well as artworks and their built surroundings, are inexorably related to each other.”
– Karim Noureldin, contemporary artist
Can a work of visual art be experienced as sound? For Karim Noureldin, it can. The Swiss artist creates abstract works that guide the eye across the composition like rhythm in music, revealing new details the longer they are viewed. Noureldin describes this as “a visual sound,” an idea rooted in drawing and reflected across works shaped by line, color, surface and space.
Noureldin’s “Brea” (2025) will be presented to view digitally as part of the new Art Basel in Basel 2026 Collection. Available exclusively on Samsung Art Store, the collection presents 24 works by Swiss and Switzerland-based artists represented by eight galleries participating in the fair. “Brea” was chosen for its distinct color palette and use of bold pattern, both central to Noureldin’s broader practice. Samsung Newsroom spoke with Noureldin about drawing, abstraction and what changes when art is experienced at home.

The Sensory Language of “Brea”

Q. “Brea” (2025) is part of the Art Basel in Basel 2026 Collection on Samsung Art Store. What can you share about the process behind this work?
“Brea” began with the process of drawing as a way to build an imagined space. I created it with pencil because drawing allows me to think, plan, imagine and picture at the same time. I have worked with pencil for a long time and I still see it as one of the most direct ways to begin an idea. The movement of drawing also feels close to writing words by hand.
Working on paper allows me to see a space that is not fully physical yet. I find it easier to create a three-dimensional world in this format than by painting on canvas. This is why drawing has remained so important to me. Its energy has been with me since early in my work as an artist and it is present in “Brea.”

Q. How do line, surface and structure work together in “Brea”?
In “Brea,” line, structure and surface are not separate elements. They build on each other. The lines create movement, the surfaces create depth and the structure holds these parts together. Through this relationship, the work can begin to feel like a space the viewer enters through their own perception. The author George Stolz has described “Brea” as creating a kind of spatiality through the way its surfaces come together. I think that is close to how I see the work.

Defining a Spatial Language
Q. How has your approach to making art stayed the same over time?
My approach has stayed the same through a steady commitment to the work. I studied fine arts, later served as an associate professor at ECAL/University of Arts and Design Lausanne and have tutored younger Swiss artists. Those experiences shaped how I think about art, but they did not change the reason I make it. I still approach each work with the same motivation and focus I had early on. Being able to make art is something I always dreamed of doing and I continue to do it with dedication and gratitude.

Q. What connects the different forms you work in?
No matter the form, my work applies the same abstract language and creative process to different media. I often think of each medium as a different instrument. The sound changes, but the composition comes from the same place. The works can appear at a small or large scale, within a specific site or as independent pieces. What connects them is the same attention to line, color, rhythm and space.

Q. What does abstraction allow you to do?
Abstraction allows for timelessness and universality. It’s not fixed to one subject or moment. It can remain open, so each viewer can meet the work through their own perception.
“Being able to make art is something I always dreamed of doing and I continue to do it with dedication and gratitude.”

Q. How do you think about the relationship between an artwork and the place where it is seen?
Space and art, as well as artworks and their built surroundings, are inexorably related to each other. Whether a work was created for a specific site, placed within one or simply viewed there, each condition shapes what the work can express and do.

How Art Forms Unity Within a Home
“When we have art in our homes, it becomes part of one’s daily life.”

Q. What feels meaningful to you about viewers encountering your work at home through Samsung Art TV?
Living with art brings art back to a private and personal space. With Samsung Art TVs, the work moves from the artist’s studio into a home, where it can be experienced daily rather than only during a visit to an institution. It helps keep visual creativity top of mind for everyone, even if they aren’t an artist.

Q. When an artwork becomes part of the home, what can repeated viewing reveal that might not be noticed at first?
When we have art in our homes, it becomes part of one’s daily life and changes with the conditions around it. Different times of day, different lighting shifts or even moods changing each time a piece is viewed. These small details can change the appearance of a work over time, making it a unified element of the home.

Q. Samsung Art Store will introduce your work to some viewers who may not know your practice yet. What would you hope they notice first in “Brea”?
I would hope they first notice “Brea” as a visual sound. By that, I mean a composition that can be felt through rhythm and movement much like music can be felt without words. Before trying to define it, I hope they spend time with every element of its structure to understand how it can speak to more than one sense.
Samsung Art Store is an art subscription service available on Samsung Art TVs including The Frame, Micro RGB and Neo QLED, offering more than 5,000 works in 4K resolution from more than 800 partners across 117 countries. As Art Basel’s official display partner, Samsung Electronics offers another way to experience contemporary art beyond the fair through exclusive Samsung Art Store digital collections featuring artists from Art Basel’s Hong Kong, Basel, Paris and Miami Beach editions.

“Instead of formulating thoughts through words, I compose with layered colors.”
– Athene Galiciadis, contemporary artist
Athene Galiciadis’ work draws its force from the movement of repeated forms. Across paintings, sculptures and installations, the Zurich-based artist uses grids, curves and blocks of color to build a formal language shaped by pattern, material experimentation and references spanning concrete art, design, craft, science and literature.
▲ Athene Galiciadis is a Zurich-based artist featured in the new Art Basel in Basel digital collection on Samsung Art Store. Photo courtesy of the artist. Galiciadis’ “Stillleben (Reflection on Longings and Belongings)” and “Stillleben (Window)” have been selected for the Art Basel in Basel (ABB) 2026 Collection on Samsung Art Store. The works were chosen for their strong use of color and pattern, qualities that translate naturally to the digital viewing experience on Samsung Art Store. Created in partnership with Art Basel, the digital collection features works by Switzerland-based artists from participating galleries and brings contemporary art from the fair to Samsung Art Store subscribers worldwide. Samsung Newsroom spoke with Galiciadis about form, color, the ideas behind the selected works and how digital presentation can bring art into the home.

A Personal Language Through Patterns
Q. Your work has a distinct language of shapes, colors and materials. How did this visual system develop?
I began developing this visual language while studying Fine Arts at ECAL(École cantonale d’art de Lausanne) in Lausanne. At the time, many artists in the Lausanne art scene were working with Neo-Geo aesthetics. I admired the rigor of that language, but I never fully connected with its precision. Rather than adopting it directly, I tried to translate it into something that felt closer to me.
▲ No two hand-painted patterns are exactly the same, with small variations giving Galiciadis’ geometric forms a sense of movement. Photo by Malle Madsen, courtesy of von Bartha Copenhagen. I started working with geometric forms, patterns, repetition and symmetry, but I deliberately embraced the handmade. Every shape was drawn or painted by hand, making it unique and slightly different from the one beside it. The patterns shifted subtly across the surface, not through a predetermined system, but through the small variations that naturally arise from manual repetition.

Q. How do you think about rhythm, variation and change within a composition?
Repetition has always been central to my practice, but I have never been interested in repetition as exact duplication. Because my forms are drawn and painted by hand, no element is ever completely identical to another. A line becomes slightly thicker, a shape shifts, a color changes in intensity. These differences accumulate and create a sense of movement across the surface.
I often think of repetition in terms of rhythm rather than pattern. A pattern suggests a fixed system, whereas rhythm allows for fluctuation, pauses, accelerations and unexpected turns. In that sense, my compositions are perhaps closer to biology than to geometry. They are structured, but never entirely predictable. They repeat, but never in exactly the same way. Over time, this visual language has become more than a tool. I see it as a placeholder for “in-betweenness,” a way to hold ambiguity, transition and multiple meanings at once.

Q. How much of a work is planned before you begin and how much is decided through the act of making it?
I usually begin with a very clear image in my mind. I think visually, so many works start as an almost complete mental picture rather than a concept expressed in words. What fascinates me is that the finished work never looks exactly like that initial image. The image has to pass through materials, gestures, scale, time and the realities of the studio. In that translation, things inevitably shift.
I do not see these deviations as mistakes or compromises. On the contrary, they are often where the work becomes most interesting. While the starting point is often highly defined, the final work is always shaped through the act of making. It is a conversation between intention and discovery, between what I envisioned and what the work itself asks for along the way.
▲ Galiciadis often lets her works shift through material, scale and space during the creative process. Photo by Stefan Altenburger, courtesy of Museum Haus Konstruktiv.
Q. Are there certain materials, colors or forms you find yourself returning to over time? If so, what keeps drawing you back to them?
Yes, there are certain forms, colors and motifs that keep returning: snakes, spirals, pinks, triangles, zigzags and many others. I do not consciously decide to revisit them; rather, they seem to reappear on their own, as if they still have something to teach me.
I often think of artistic research as a spiral rather than a linear progression. You engage with something, move away from it, explore other directions and then return to it later. But when you come back, neither you nor the motif is quite the same. Perhaps this is why I am drawn to recurring forms. They become companions in a long-term conversation. Each time they reappear, they carry traces of previous works while opening up new questions and possibilities.

The Meaning of “Stillleben”
“The same structures that provide comfort and a sense of home can also become mechanisms of separation and exclusion.”

Q. Your palette often moves between soft pinks, greens and yellows, with darker blues and blacks adding contrast. How do you think about color as a way to shape tension, depth or atmosphere?
For me, color is something deeply personal. I do not approach it primarily as a decorative element or as a way of illustrating an idea. Rather, color is a way of thinking and a form of artistic research.
In many ways, this process replaces language. Instead of formulating thoughts through words, I compose with layered colors. Through this slow accumulation, I search for nuances, tensions and relationships that are difficult for me to articulate verbally. The depth that emerges is not only visual but also emotional and conceptual.

Q. What can you share about the works selected for the Art Basel in Basel 2026 Collection on Samsung Art Store and the moment in which they were made?
This work emerged within a larger constellation of paintings that I was developing simultaneously in the studio. I rarely work on a single canvas at a time. Instead, several works evolve alongside one another, creating a kind of conversation. What appears on one canvas often migrates to another; a color, form, rhythm or idea that begins in one painting may find a different articulation in the next.
▲ From left. “Stillleben (Window)” (2023) by Athene Galiciadis. Photo by Malle Madsen.
 “Stillleben (Reflection on Longings and Belongings)” (2021) by Athene Galiciadis. Photo by Andreas Zimmermann. Both works were created within such a process. They carry traces of multiple explorations and conversations taking place across different canvases at the same time. Looking back, I see each work as part of an ongoing reflection on questions that continue to occupy me: belonging, displacement, memory, inheritance and transformation. Rather than offering answers, the painting became a space where these themes could coexist and interact.

Q. How did the title “Stillleben (Reflection on Longings and Belongings)” come to the work and what does it add to the viewer’s understanding of the piece?
The title emerged from two conditions that often feel inseparable. Questions of migration, displacement, in-betweenness, transformation, inheritance and identity run throughout my practice and shape how I understand the world. What does it mean to belong? Who is included and who remains outside? Belonging can offer shelter, care and nourishment, but it can also produce boundaries and exclusions.
Longing is particularly difficult to describe. For me, it is often connected to a desire to bridge a gap that is always present but was never entirely my own. It can be inherited across generations, carried through stories, silences, memories and cultural interruptions. It is a longing for connection, continuity and understanding, while knowing that some distances can never be fully overcome.
The same structures that provide comfort and a sense of home can also become mechanisms of separation and exclusion. For me, “Stillleben (Reflection on Longings and Belongings)”inhabits this space of contradiction. It reflects on the simultaneous desire to belong and the awareness that belonging is never simple, fixed or innocent.

Where Art Finds New Meaning at Home
Q. Samsung Art Store gives people a way to encounter world-class art in the spaces where they live. What interests you about that everyday relationship with artwork?
What interests me most is the possibility of creating an everyday relationship with art. Some of the most meaningful encounters with artworks happen not in museums, but in the spaces where we live and spend our time. When you encounter an artwork repeatedly, it becomes part of your daily life and the relationship deepens over time to become a piece of your memories and personal history.
This resonates with my interest in collaboration, participation and community building. I enjoy forms of access that allow art to enter everyday environments. Through projects such as Actioning, I have explored how meaning emerges through shared experiences and sustained engagement. I see art as something that can create connections and become part of a shared cultural life.

Q. How do you think the experience of viewing art changes when a work becomes part of a home environment?
I think the experience becomes slower and more intimate. In a museum, we often encounter artworks briefly and alongside many others. At home, the relationship unfolds over time and the artwork becomes part of everyday life.
You might notice it while drinking your morning coffee, passing through a room or returning home after a difficult day. Sometimes you look closely; other times it simply exists in the background. Yet it continues to shape the atmosphere of a space.
▲ “Stillleben (Reflection on Longings and Belongings)” (2021) by Athene Galiciadis is displayed on the 2026 OLED TV S95H. The work becomes an ongoing relationship. Meanings can shift over time and details that initially went unnoticed may suddenly become important. As the viewer changes, the work changes too. This reflects how I understand art: not as a fixed message, but as something open that continues to generate new associations.
“Some of the most meaningful encounters with artworks happen not in museums, but in the spaces where we live and spend our time.”

Q. For viewers who may discover your work for the first time through Samsung Art Store, what would you hope they take time to notice?
I would invite them to spend a little time with the work and allow their eyes to wander. At first glance, my paintings may appear structured, repetitive or geometric. But if you stay with them for a while, small shifts, irregularities and transformations begin to emerge.
I hope viewers notice that nothing is ever entirely fixed. Forms repeat, but they also change. Colors overlap, reveal and conceal one another. What may initially seem stable gradually becomes more fluid and complex.
Perhaps most of all, I hope people allow themselves to experience the work without feeling the need to immediately understand or interpret it. Much of my practice is concerned with things that exist between categories: between belonging and displacement, order and unpredictability, memory and imagination. These are experiences that cannot always be translated into words.
If viewers take the time to notice the rhythms, layers and subtle variations within the work, they may discover that the painting is less about providing answers than about creating space for reflection, curiosity and personal associations. I hope everyone can find their own point of entry and build their own relationship with the work over time.

For a game developer working on live service games, managing subscriptions effectively can make or break your monetization strategy. In a previous blog article, you have learned how to integrate the Samsung IAP plugin into a basic Unreal Engine game. This time, you learn how to implement a complete subscription workflow using the updated Samsung IAP Unreal Engine Plugin.
The Samsung IAP plugin for Unreal Engine has been updated to reach feature parity with the Samsung IAP SDK. The plugin introduces multiple new APIs allowing you to easily integrate a complete subscription management workflow in your games. Using these APIs, you can check promotional offer eligibility, purchase and change subscription plans, acknowledge purchases, and so on. This update also introduces Boolean return types similar to the base Samsung IAP SDK to check if an API call was executed successfully.
This article demonstrates how you can integrate the Samsung IAP plugin into Unreal Engine games to enable users to check subscription promotional pricing eligibility, purchase in-app products, acknowledge purchases, and change subscription plans.
Prerequisites
The demonstration in this article uses the following recommended development environment:
Unreal Engine 5.7 Visual Studio 2022 Professional Android SDK: Android SDK API Level 35 Android NDK r27c CMake 3.10.2 Build tools 36 Setting Up the Development Environment
To set up your Unreal Engine game project to implement the Samsung IAP plugin:
Open an existing Unreal Engine project or create a new project. If the project is not already configured for Android, go to Edit > Project Settings > Platforms > Android , and click Configure Now. Set the Android Package Name from the Platforms > Android tab. Download the Samsung IAP Unreal Engine Plugin from the Samsung Developer website. Extract the content of the downloaded file inside the Plugins folder of your project directory. If the /Plugins/ folder does not exist, you must create it. In the /Source/ folder, open the <project_name>.build.cs file. In the PublicDependencyModuleNames.AddRange() section, add SamsungIAP to the list. PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "EnhancedInput", "SamsungIAP" }); Relaunch Unreal Engine. Go to Edit > Plugins > Installed > Service and tick the checkbox next to Samsung IAP Plugin to enable the plugin. Registering In-App Products in Galaxy Store Seller Portal
In live service game monetization, two types of in-app products are most common. These are one-time purchasable cosmetic items and monthly recurring subscriptions. To allow the implementation of both types of in-app products, Samsung Galaxy Store Seller Portal also allows you to register two types of products: item and subscription.
The next step of the demonstration is to register two types of subscriptions called basic and premium, and one item called weapon_skin.
Package the binary for testing. In the Unreal Engine toolbar, select Platforms > Package Project > Android. Register your game application in Seller Portal, filling in the required information. In the Binary tab of Seller Portal, upload your game's packaged binary file. In the In-App Purchase tab, create your in-app products and activate them. For this demonstration, create the following products: basic - A lower priced subscription. premium – A higher priced subscription. weapon_skin – An item for demonstration of one-time purchases.
For subscriptions, you can also add free-trial or introductory promotional pricing options if you wish. Check Subscription Pricing Options. To save the game information and IAP item details, select Save. Finally, register tester accounts from Galaxy Store Seller Portal > Profile to enable testing IAP functionality. Integrating In-App Purchases in Your Game
Now that the game application and its IAP items are registered, you can begin implementing the Samsung IAP features in your game.
Step 1: Include the IAP header file
To access the Samsung IAP functions in your project, you must add the header file to the Unreal Engine project source code:
In Unreal Engine, select Tools > Refresh Visual Studio project. To open and edit the project code in Visual Studio, select Tools > Open Visual Studio. Navigate to the C++ code file and open it in the editor. Include the Samsung IAP Unreal Engine Plugin header file in your code: #include "IAP.h" Now you can access the APIs provided by Samsung IAP from your code.
Step 2: Set the IAP operation mode
The Samsung IAP Unreal Engine Plugin has three operation modes:
IAP_MODE_TEST: For development and testing. IAP_MODE_PRODUCTION: For public beta and production releases. IAP_MODE_TEST_FAILURE: For testing failure cases. In this mode, all requests return failure responses. The operation mode can be set using the setOperationMode(<IAP MODE>) function.
Since the game is in development, use IAP_MODE_TEST.
#if PLATFORM_ANDROID samsung::IAP::setOperationMode(IAP_MODE_TEST); #endif Step 3: Create and set a listener class for callback functions
The updated Samsung IAP Unreal Engine Plugin has 7 main API functions. Each of these functions requires a listener or callback function that handles the data returned from the IAP library function. Create a listener class with the callback functions for all the APIs. The callback functions are:
onGetProducts() is the listener for getProductDetails(). onGetOwnedProducts() is the listener for getOwnedList(). onPayment() is the listener for startPayment(). onConsumePurchasedItems() is the listener for consumePurchasedItems(). onAcknowledgePurchases() is the listener for acknowledgePurchases(). onGetPromotionEligibility() is the listener for getPromotionEligibility(). onChangeSubscriptionPlan() is the listener for changeSubscriptionPlan(). In this example, a C++ class named SamsungIAPListener is created in Unreal Engine, generating the SamsungIAPListener.cpp and SamsungIAPListener.h files in the project source directory.
In the SamsungIAPListener.h file, define the class with function declarations:
#pragma once #include "CoreMinimal.h" #include "IAP.h" class SamsungIAPListener : public samsung::IAPListener { public: void onGetProducts(int result, const FString& msg, const std::vector<samsung::ProductVo>& data); void onGetOwnedProducts(int result, const FString& msg, const std::vector<samsung::OwnedProductVo>& data); void onPayment(int result, const FString& msg, const samsung::PurchaseVo& data); void onConsumePurchasedItems(int result, const FString& msg, const std::vector<samsung::ConsumeVo>& data); void onAcknowledgePurchases(int result, const FString& msg, const std::vector<samsung::AcknowledgeVo>& data); void onGetPromotionEligibility(int result, const FString& msg, const std::vector<samsung::PromotionEligibilityVo>& data); void onChangeSubscriptionPlan(int result, const FString& msg, const samsung::PurchaseVo& data); }; In the SamsungIAPListener.cpp file, create minimal skeleton code for the callback functions as well so that the project compiles without any issues.
Next, in the main code file, to set the SamsungIAPListener listener class that was just created as the IAP listener class for the project, use the setListener() function.
#if PLATFORM_ANDROID samsung::IAP::setListener(new SamsungIAPListener); #endif } Step 4: Check if promotional pricing is available for subscriptions
Seller Portal allows setting promotional prices, such as free trials and introductory prices for the first time purchase of a subscription. To complement this, Samsung IAP also provides an API for checking if any such promotional offers are currently available for the user. This is the getPromotionEligibility() function. You can use it to check which pricing is available for the user and then display the best available pricing options to encourage subscription purchases.
Call the method and specify one or more comma-delimited subscription item IDs.
result = samsung::IAP::getPromotionEligibility("basic,premium"); Once the request is processed, the result is provided in the onGetPromotionEligibility() callback function, which contains information about the promotional pricing for each mentioned subscription.
void SamsungIAPListener::onGetPromotionEligibility(int result, const FString& msg, const std::vector<PromotionEligibilityVo>& data) { for (auto& i : data) { UE_LOG(LogTemp, Display, TEXT("Pricing type for %s: - %s"), *i.itemID, *i.pricing); } } The pricing field indicates the type of promotional pricing available. Depending on how you registered the subscriptions in Seller Portal, the subscriptions should display one of the following 3 types of pricing:
FreeTrial: The user is eligible for a free trial period. TieredPrice: The user is eligible for an introductory price. RegularPrice: The user is not eligible for any promotions. Step 5: Purchase in-app items and subscriptions
In Samsung IAP, the process of purchasing both items and subscriptions are similar. The startPayment() function is used for purchasing both types of products. In this next step, you will learn how to purchase one-time purchasable items (also known as non-consumable items) and subscriptions using the startPayment() function.
The startPayment() function now accepts obfuscated account ID and obfuscated profile ID parameters. These obfuscated identifiers are returned in the purchase response for verification. Purchase the weapon_skin item using the following code:
samsung::IAP::startPayment("weapon_skin", "obfuscatedAccountId", "obfuscatedProfileId"); If the startPayment() API call is successful, the result of the purchase is returned to the onPayment() callback function. Save the purchase ID for acknowledging the purchase later.
void SamsungIAPListener::onPayment(int result, const FString& msg, const PurchaseVo& data) { PurchaseIDHelper::setSavedPurchaseID(*data.mPurchaseId); } Purchasing a subscription is similar to purchasing items since the startPayment() function is also used for purchasing subscriptions.
Purchase the basic subscription by using the startPayment() method. The result of this purchase is also returned to the onPayment() callback function.
Purchase the basic subscription:
samsung::IAP::startPayment("basic", "obfuscatedAccountId", "obfuscatedProfileId"); To check if the items and subscriptions have been added to the user's owned product list, you can use the getOwnedList("all") function.
At this stage, the purchased products exist in a non-acknowledged state. Next, you need to either consume or acknowledge the purchase depending on the intended product type and use case.
Step 6: Verify the purchases using the Samsung IAP Server APIs
Samsung IAP also allows you to query and verify purchases from the server side using the Samsung IAP Server APIs. While this step is completely optional, it is highly recommended if you wish to double-check and ensure the authenticity of the purchase before granting users access to the purchased products.
To verify purchases, store the purchase ID and send a GET request to the Samsung IAP server using the following endpoint:
https://iap.samsungapps.com/iap/v6/receipt?purchaseID={purchaseID value}
Replace {purchaseID value} with the actual purchase ID to retrieve the purchase receipt and validate the transaction.
If the purchase ID is valid, you receive the complete purchase information from the Samsung IAP server:
{ "itemId": "Basic", "paymentId": "TPMTID20260606US18339044", "orderId": "P20260606US18339044", "packageName": "com.example.game", "itemName": "Basic Subscription", "itemDesc": "Basic Subscription Detail", "purchaseDate": "2026-06-06 09:13:16", "paymentAmount": "1.0", "status": "success", "paymentMethod": "Credit Card", "mode": "TEST", "consumeYN": "N", "consumeDate": "", "consumeDeviceModel": "", "acknowledgeYN": "N", "acknowledgeDate": "", "acknowledgeDeviceModel": "", "currencyCode": "USD", "currencyUnit": "$", "minorStatus": "NOT_MINOR" } NoteFor real purchases in a production environment, the mode field value is PRODUCTION instead of TEST. And if the purchase is invalid and the purchase ID does not exist, the request simply returns a "not exist order" error.
{ "status": "fail", "errorCode": 9135, "errorMessage": "not exist order" } Once you verify the purchase from your server, you can now consume or acknowledge the purchases and provide the user with the purchased products.
Step 7: Acknowledge purchased non-consumable items and subscriptions
In order to make these purchases permanent, you must acknowledge non-consumable / one-time purchasable items and subscriptions using the acknowledgePurchases() function. Use the acknowledgePurchases() function with the purchase IDs of the non-consumable items or subscriptions in order to acknowledge the purchases. To learn more about acknowledging non-consumable items and subscriptions, check the Samsung IAP documentation.
FString savedPId = PurchaseIDHelper::getSavedPurchaseID(); samsung::IAP::acknowledgePurchases(savedPId); This operation informs Samsung IAP that the user has been granted entitlement for the purchased product. Once a product purchase has been acknowledged, the product cannot be consumed or purchased again.
When the acknowledgment is processed, the onAcknowledgePurchases() callback function is called. In this callback function, you can verify the acknowledgment status and store the purchase details locally.
void SamsungIAPListener::onAcknowledgePurchases(int result, const FString& msg, const std::vector<AcknowledgeVo>& data) { for (auto& i : data) { UE_LOG(LogTemp, Display, TEXT("Product Acknowledge Status: %s"), *i.mStatusString); } } You can also check the acknowledgment status of an owned item through the acknowledgedStatus field in the OwnedProductVo data returned by getOwnedList(). The possible values are:
ACKNOWLEDGED: The purchase has been acknowledged. NOT_ACKNOWLEDGED: The purchase has not been acknowledged. UNSUPPORTED: Acknowledgment is not supported for this product. Step 8: Change subscription plan
Finally, you can allow users to upgrade or downgrade their existing subscriptions using the changeSubscriptionPlan() function. For example, a user subscribed to the basic plan can upgrade to the premium plan using this function.
samsung::IAP::changeSubscriptionPlan("basic", "premium", PRORATION_MODE_INSTANT_PRORATED_DATE, "obfuscatedAccountId", "obfuscatedProfileId"); Here the first parameter is the existing subscription ID, the second parameter is the new subscription ID, the third value is the proration mode, and the fourth and fifth parameters are the obfuscated account and profile ID.
Samsung IAP supports four proration modes that determine how the billing transition is handled:
PRORATION_MODE_INSTANT_PRORATED_DATE: The subscription is upgraded or downgraded immediately. Remaining time is adjusted by crediting the price difference, and the next billing date is pushed forward. There is no additional payment. PRORATION_MODE_INSTANT_PRORATED_CHARGE: For upgraded subscriptions only. The subscription is upgraded immediately but the billing cycle remains the same. The price difference for the remaining period is then charged to the user. PRORATION_MODE_INSTANT_NO_PRORATION: For upgraded subscriptions only. The subscription is upgraded immediately and the new price is charged when the subscription renews. The billing cycle remains the same. PRORATION_MODE_DEFERRED: The subscription is upgraded or downgraded when the subscription renews. When the subscription renews, the new price is charged. A downgrade is always executed with this mode. You can find more information about proration modes in the Samsung IAP documentation.
Once the subscription plan change is processed, the result is returned to the onChangeSubscriptionPlan() callback function, which contains information about the purchased product and the transaction.
void SamsungIAPListener::onChangeSubscriptionPlan(int result, const FString& msg, const samsung::PurchaseVo& data) { FString newId = TEXT("premium"); if (newId.Equals(*data.mItemId)) { UE_LOG(LogTemp, Display, TEXT("Subscription plan changed to premium")); } } Summary
With the Samsung IAP feature fully integrated into your live service Unreal Engine game, you can now test the IAP functionality within the game and confirm that the monetization of your game progresses without any hitches.
For subscription items, the updated Samsung IAP Unreal Engine Plugin enables a complete subscription management workflow:
getPromotionEligibility() checks if the user qualifies for free trials or introductory pricing on subscriptions. startPayment() initiates the subscription purchase with obfuscated identifiers for enhanced security. acknowledgePurchases() confirms that the user has been granted entitlement for the subscription. changeSubscriptionPlan() allows the user to upgrade or downgrade their subscription with flexible proration modes. The Samsung IAP Unreal Engine Plugin brings significant improvements over the previous versions, giving you the tools to build a complete and secure in-app purchase experience.

Samsung Electronics, global display leader and provider of the Official Art TV of Art Basel, today announced the launch of the Art Basel in Basel (ABB) 2026 Collection, a curated digital exhibition available exclusively on Samsung Art Store. The collection brings together 24 works by Swiss and Switzerland-based artists from eight renowned galleries exhibiting at Art Basel in Basel 2026, held from June 18-21 in Switzerland.
“Basel has a distinct place in the art world, and this collection reflects the creative range that makes the fair so meaningful,” said Hun Lee, Executive Vice President of Visual Display (VD) Business at Samsung Electronics. “Through our longstanding partnership with Art Basel, we are helping customers turn their screens into a personal space for discovering, displaying and living with art.”
Reflecting the range of artistic voices across the Swiss art scene, the ABB 2026 Collection will be available on Samsung Art Store starting today. The digital collection is a continuation of Samsung and Art Basel’s global partnership and brings select works from Art Basel fairs to Samsung Art TV users around the world.

A Closer Look at the ABB 2026 Collection
The ABB 2026 Collection offers a regional view of Art Basel in Basel through established names and rising talent from eight galleries. Participating galleries include Mai 36, von Bartha, Skopia and Blue Velvet from Switzerland, along with Fanta MLN, Hoffmann Donahue, Lars Friedrich, Sans titre and Felix Gaudlitz.
At its core, the collection highlights three Swiss-born artists spanning multiple generations of contemporary practice:
Thomas Huber’s “16.7.2024” reflects his distinctive approach to painting, where image and text converge to explore picture space as both a visual and philosophical construction.
Tobias Kaspar’s “The Japan Collection” examines systems of value, taste and desire through a multidisciplinary practice that bridges art and fashion.
Athene Galiciadis’s “Stillleben (Reflection on longings and belongings)” presents a richly layered visual language, combining geometric and organic forms with references to craft, design, science and spirituality.
“Basel is a city where art is experienced with great depth and attention, and I am pleased that this spirit is reflected in the Samsung Art Store’s ABB 2026 Collection,” said Maike Cruse, Director of Art Basel in Basel. “Together with Samsung, we highlight artists based in Switzerland. The collection reflects the richness, diversity and vitality of the region while reinforcing our commitment to connecting regional scenes with a global audience.”

Bringing Samsung Art Store to Life at Art Basel
At this year’s Art Basel in Basel, visitors can experience Samsung Art Store through an immersive installation that shows how art can move beyond the gallery and into everyday spaces. The experience will feature a gallery-style Art Wall composed of displays from Samsung’s 2026 Art TV lineup, including Micro RGB, OLED, The Frame Pro and The Frame. The Art Wall will showcase selected works based on attendees’ visual preferences and offer a preview of the ABB 2026 Collection, highlighting how Samsung display technology can make art feel more personal in the home.
Samsung’s Art Basel exhibit will also feature a collaboration with visual artist Daniel Arsham, Samsung’s new Art TV ambassador. Designed for The Frame Pro, Arsham’s custom bezel turns the TV frame into a sculptural surface, with a three-dimensional pattern inspired by topographical mapping data. It is paired with on-screen artwork inspired by erosion patterns and crystalline forms, extending the work into the surrounding space and reflecting Arsham’s exploration of time, material and everyday objects.

Samsung Electronics today announced a new collaboration with MUNCH to add iconic artworks by Edvard Munch to Samsung Art Store. The digital collection makes 37 masterpieces such as “The Scream,” “The Dance of Life” and “Melancholy” — as well as several rare works from the museum’s collection — available to millions of users around the world.
“Samsung creates products that inspire people and help them express themselves through design and culture,” said Tommy Nilsson, TV & Audio Director at Samsung Nordics. “With Samsung Art Store, we make world-class art available to millions of people and through this collaboration with MUNCH, we are bringing an important part of European artistic heritage into people’s homes.”

Samsung Art Store Opens Up MUNCH Archives
Alongside Munch’s iconic masterpieces, the collection offers a more intimate view of Edvard Munch’s artistry with rarely seen works such as “Garden with Trees” and “Two People at Table.” These works are part of a collection of treasures preserved in the museum’s archives, many of which must be kept in carefully controlled environments to protect them from further deterioration. Their condition makes them too vulnerable for public display, even at the museum in Oslo.
“This collaboration is an exciting opportunity to share Edvard Munch’s art with audiences beyond the museum’s walls in Oslo,” said Tone Hansen, Director of MUNCH. “Through Samsung’s global reach and Art TV technology, we can make Munch’s work more accessible to people around the world and we are incredibly honored to collaborate with Samsung on this meaningful initiative.”
The collection will be exclusively available on Samsung’s Art TV lineup through Samsung Art Store, providing users with a close look at Munch’s private world by allowing them to explore and display the artist’s hidden gems at home.

Where Technology Meets Fine Art
Samsung is redefining the role of the TV in the home by merging premium display technology with elegant designs that blend naturally with any interior. As Samsung Art Store expands across the Art TV lineup, which includes The Frame, OLED, Neo QLED and Micro RGB,1 the company is connecting everyday interiors with curated artwork from leading museums, galleries and artists.
Through Samsung Art Store, users can access more than 5,000 artworks from renowned artists and institutions, now including works from MUNCH. Each piece is faithfully reproduced in high quality, allowing people around the world to enjoy art as part of everyday life. Current owners of compatible Samsung TVs in Europe who are new to Samsung Art Store can enjoy a complimentary 90-day subscription trial, providing immediate access to the complete Munch collection and the broader Samsung Art Store catalog.2
The artworks selected from MUNCH will be available worldwide on Samsung Art Store starting June 1, 2026.
