Samsung’s Galaxy A53 leaked not too long ago, and we told you at the time the 2022 mid-ranger would dominate the Galaxy S22. That was before all of the Galaxy S22 controversies. The prediction was based on the A53’s predecessors’ sales performance. Those phones outsold their Galaxy S contemporaries in previous years.
Fast-forward to Wednesday, and Samsung has finally launched the Galaxy A53. The phone offers truly incredible value for anyone looking for decent performance for the right price. And the price, by the way, just got better. Add to that the same four years of Android guarantees and 5G support of the Galaxy S22, and you get a Samsung phone that can easily outsell a flagship.
Don't Miss: Wednesday’s deals: $50 Echo Buds, secret Fire TV deal, Oral-B sale, Samsung monitors, more Like the iPhone SE 3, the Galaxy A53 is similar to the previous generation. Galaxy A52 users will find the hole-punch design similar. The same goes for the rear-facing plastic back. They’ll expect 6GB of RAM and 128GB of storage for the cheapest model.
That’s precisely what Samsung delivers with the Galaxy A53. We’ve got a 6.5-inch OLED screen with a 120Hz refresh rate, Full HD resolution, and a built-in fingerprint sensor. The camera system on the back is also in line with expectations: 64-megapixel primary sensor, 12-megapixel ultra-wide camera, and two 5-megapixel depth and macro lenses. A 32-megapixel shooter pierces the screen.

What changed on the Galaxy A53 is the processor. Instead of a Snapdragon System-on-Chip (SoC), you’ll get the Exynos 1280 5nm chip. Or the kind of SoC that Samsung can throttle and nobody will care. Put differently; the Galaxy A53 won’t touch the iPhone SE 3 when it comes to performance.
Also new is the 5,000 mAh battery, which Samsung says will last for two days on a single charge. That’s 25W charging, by the way. Add IP67 water and dust resistance, and the Galaxy A53 should be on any list of mid-range devices.
That’s especially considering that Samsung cut the Galaxy A53 price by $50. The phone is available for preorder starting at $449.99 before any trade-in or other deals. Moreover, you get a free pair of Galaxy Buds Live, which retail for $169.99 otherwise. The Galaxy A53 will ship to buyers on April 1st.
The four years of Android updates should clinch this deal, as it ensures you’ll be on the latest version of Android for the entire period you might want to use the phone. You also get five years of security upgrades.

While US buyers are only getting the Galaxy A53, Samsung launched two additional A-series models on Wednesday. The Galaxy A33 is the cheaper version of the Galaxy A53. Also a 5G phone, the Galaxy A53 has a slightly smaller display at 6.4-inch. And it only offers support for 90Hz refresh rates.
Also notable is the display design. This isn’t a hole-punch display. Instead, it has a camera notch at the top and a larger bottom bezel. The primary rear camera also gets a downgrade to a 48-megapixel sensor.
Otherwise, the Galaxy A33 is identical to the Galaxy A53. But the phone will retail in Europe for €369. The Galaxy A53’s price in Europe is €449, implying the Galaxy A33 would cost $369 in the US. But, again, Samsung isn’t launching the more affordable A-series phone in the States.
Finally, there’s the higher-end Galaxy A72, which isn’t getting a US launch either. The phone packs a larger 6.7-inch OLED screen, a Snapdragon 778G SoC, and a 108-megapixel primary camera. The phone will go on sale in select markets on April 22nd, for an undisclosed price. The Galaxy A33 5G will also hit various markets on April 22nd.

This blog is the fourth in a series of posts about Remote Test Lab (RTL). In previous blogs, we covered what is Remote Test Lab, its new features, and Auto Repeat. In this blog, we show you how to connect RTL to Android Studio and how to deploy and debug your app on the remote device. In an upcoming blog, we are going to take a deep dive into some additional features of Remote Test Lab.
Remote Test Lab allows you to run and debug your application on real devices remotely. In this blog, we will connect a Remote Test Lab device with a local development machine’s ADB (Android Debug Bridge) using Remote Debug Bridge.
The Remote Debug Bridge tool enables you to run and debug your app to check compatibility with the latest Samsung mobile devices, which solves the problem of not having your own physical devices.
Connect your Remote Test Lab device to Android Studio
To get started, launch a Remote Test Lab client, then go to Remote Test Lab and reserve one of the available mobile devices.
The operating system version, device location, and desired time can be selected on the Remote Test Lab page. A JNLP file is downloaded to your computer when you click the Start button. If you run this file, the Remote Test Lab client is launched and a live image of the device is shown in the client.
Step 1. When the live image is shown, right-click on the device's screen and select ‘Test > Remote Debug Bridge.’
Step 2. In the pop-up window, view the required command and port number to connect your Android Studio to the Remote Test Lab device.
Step 3. Open a Command Prompt window and run the ADB command with the given port number. In this example, the command is:
adb connect localhost:50964
Note: You must accept the RSA key prompt by allowing USB debugging when you run the ADB connect command for the first time on a Remote Test Lab device.
Deploy and debug apps from Android Studio
Step 1. The device is now ready to deploy your app from Android Studio. Build and run your app from Android Studio. In the following screenshot, an app is being deployed on a Remote Test Lab device from Android Studio.
Step 2. The app is deployed and launched successfully on the Remote Test Lab device
Step 3. Debug your app from Android Studio just like on a real device.
In conclusion, Remote Test Lab offers a convenient and effective way to check the compatibility of your app and use debug facilities. Finally, our developer forum is an excellent way to stay up-to-date on all things related to the Samsung Galaxy ecosystem.

Selling digital content is a popular business all over the world. If you are interested in selling your digital items in the Samsung ecosystem, then you need to learn about the Samsung In-App Purchase (IAP) SDK. You can implement Samsung IAP in your Android, Unity, and Unreal Applications.
Since server to server communication is more secure and reliable, payment transaction should be verified from the IAP server. This is the second of two blogs on this topic. In the first part, we discussed how to integrate Samsung’s IAP server API into your app’s server. In this blog, we will learn how to communicate with your server through an Android app.
Please go through the documentation of Samsung IAP SDK to integrate Samsung IAP SDK in your app. Then build your own app server for server verification which is covered in the first part of this blog. To know about server API, read Samsung IAP Server API.
Get Started
Let’s learn through a simple Android game. This game has an item which can only be used for a certain period of time. So, it is a subscription type item. If a user buys this item, then the item will be available after purchase verification.
When the app is launched, the app checks if this item is already subscribed or not. There can be one of two results:
The item is not subscribed, then the app offers to subscribe this item. The item is subscribed then the app gets the current status of this subscription through getSubscriptionStatus Server API. The subscription status can be active or cancel. Subscription can be canceled for various reasons. If the IAP server returns the subscription status as ‘cancel’ then the app notifies it to the user. Implementation of these two cases are discussed in the next sections.
Implement Android IAP
At first, integrate Samsung IAP SDK in your Android app and register it in the seller office to test In-App items. When the app is launched, call getOwnedList() API. It returns a list of in-app items that the app user currently has from previous purchases. If the item is not in this list, then the app offers to purchase the item.
To purchase any item, call startPayment(). This API notifies the end user if the purchase succeeded or failed. If the purchase is successful, then do the server verification. If your app’s server validates the purchase, then make the item available to the user, otherwise request user to purchase it again.
public void onPayment(ErrorVo _errorVo, PurchaseVo _purchaseVo) { if (_errorVo != null) { if (_errorVo.getErrorCode() == IapHelper.IAP_ERROR_NONE) { if (_purchaseVo != null) { if (mPassThroughParam != null && _purchaseVo.getPassThroughParam() != null) { if (mPassThroughParam.equals(_purchaseVo.getPassThroughParam())) { if (_purchaseVo.getItemId().equals(ITEM_ID_SUBSCRIPTION)) { mMainActivity.setBackgroundPurchaseId(_purchaseVo.getPurchaseId()); new PurchaseVerification(mMainActivity).execute(_purchaseVo.getPurchaseId()); } } } } } } } If the item is available in this list, then detailed information of this item such as purchase ID will be available in the OwnedProductVo type ArrayList. To call getSubscriptionStatus Server API, we need the purchase ID of the item. So, send this ID to your app’s server to get the status of the subscribed item.
public void onGetOwnedProducts(ErrorVo _errorVo, ArrayList<OwnedProductVo> _ownedList) { if (_errorVo != null) { if (_errorVo.getErrorCode() == IapHelper.IAP_ERROR_NONE) { if (_ownedList != null) { for (OwnedProductVo item : _ownedList) { if (item.getItemId().compareTo(ItemName.ITEM_ID_SUBSCRIPTION) == 0) { // Check whether subscription is canceled or not. new SubscriptionDetails(mMainActivity).execute(item.getPurchaseId()); } } } } else { Log.e(TAG, "onGetOwnedProducts ErrorCode [" + _errorVo.getErrorCode() +"]"); } } } Connect Your App with Your App Server
Create an asynchronous task for communicating with the server. This task has two parts. One is to send purchase ID to your app server and the other is to receive the result from the app server. Use doInBackground() method for these two tasks. Return this result to your main UI through onPostExecute() method.
Create a class which extends AsyncTask<String,Void,String> for server verification. Then write the following code in doInBackground() method to send the purchase ID:
CookieHandler.setDefault( new CookieManager( null, CookiePolicy.ACCEPT_ALL ) ); try{ URL url = new URL("http:// "); //URL of your app’ server URLConnection connection = url.openConnection(); connection.setDoOutput(true); connection.setDoInput(true); OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream(); String y = ""; for(int i = 0;i < x.length;i++) { y = y + x[i]; } out.write(y); out.close(); }catch(Exception e){ } Receive to the server verification result using the following code:
String output = ""; BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); String s = ""; while((s = in.readLine())!= null) { output = output + s; in.close(); } return output; Now, create an Interface called ServerResponse and implement it in an Activity where you want to show the result from your app’s server.
public interface ServerResponse { void processFinish(String output); } After receiving the result from the server, return the result to your main UI through onPostExecute() method.
protected void onPostExecute(String result) { serverresponse.processFinish(result); } Test your app
Let’s test the app. Upload your web app onto a server. Then use that URL in your app to check server verification in doInBackground() method. Keep in mind that Samsung In-App Purchase can’t be tested in an emulator of Android Studio. So use a Samsung device to test your app. Read the Test Guide before starting to test your app. A simple Android game is attached at the end of this article where app to server communication is implemented.
This game has a blue background image which can be subscribed. If this item is not in an active subscription period, then the app offers to subscribe the background. If the user purchases the item, then the game verifies the purchase through the server. If the purchase is verified, then it shows that the subscription status is activated and the app makes the item available. If the user unsubscribes the item from the Galaxy Store, subscription status becomes ‘cancel’. However, as the active subscription period has not ended yet, the item is still available in the app.
Wrapping Up
In these two blogs, we have covered the full communication between your app, server and IAP server. Now you will be able to implement purchase verification through your server. If your app is free but has some premium contents, then you can monetize your app. Samsung In-App Purchase provides many ways to earn money from your app. Go to Galaxy Store Games to find out more details about it.

Game performance can vary between different Android devices, because they use different chipsets, and GPUs based on different Mali architectures. Your game may render at 60fps on a Galaxy S20+, but how will it perform on the Galaxy A51 5G? The A51 5G has good specs, but you may want to consider runtime changes based on the underlying hardware if your game is pushing the limits on flagship hardware. Similarly, you may need to optimize your game to run at lower frame rates on the Galaxy J and Galaxy M models, which are often found in emerging markets.
Players quickly lose interest in a game if they experience drops in frame rate, or slow load times. They won’t play your game on long journeys if it drains battery or overheats the device. To reliably deploy a game globally, and ensure a great user experience, you need to performance test on a wide range of Android devices.
The Arm Mobile Studio family of performance analysis tools provide games studios with a comprehensive game analysis workflow for Android, giving information and advice at appropriate levels of detail, for technical artists, graphics developers, performance analysts and project leaders.
Monitor CPU and GPU activity
Arm Streamline captures a comprehensive profile of your game running on an unrooted Android device, and visualizes the CPU and GPU performance counter activity as you run your test scenario. You can see exactly how the CPU and GPU workloads are handled by the device, which helps you locate problem areas that might explain frame rate drops or thermal problems.
However, spotting performance issues using Streamline can be time-consuming, unless you know exactly what you’re looking for. Your team may have varying levels of experience or expertise, so interpreting this data can be difficult.
Introducing Performance Advisor
Arm Performance Advisor is a lightweight reporting tool that transforms a Streamline capture into a simple report that describes how your game performed on the device, and alerts you to problem areas that you should consider optimizing. It can be used by your whole team on a regular basis, to spot trends and diagnose problems early in the development cycle, when you’re best placed to do something about it.
Performance Advisor reports the application frame rate, CPU load and GPU load, as well as content metrics about the workload running on the Mali GPU. If it detects problematic areas, Performance Advisor tells you whether it’s the CPU or GPU that is struggling to process your application, and links to optimization advice to help you rectify it.
A frame rate analysis chart shows how the application performed over time. The background color of the chart indicates how the game performed. When you’re hitting your target frame rate, the chart background is green. In this example, most of the chart is blue, telling us the GPU in the device is struggling to process fragment workloads.
Performance Advisor can capture screenshots of your game, at the point that FPS drops below a given threshold. This helps you to identify which content might be causing the problem. This provides valuable context when debugging and can allow some common elements to be spotted if repeated slowdowns occur. You can then investigate these frames more closely with Graphics Analyzer, to see exactly which graphics API calls were executing at that point.
If you want to separately evaluate how different parts of the game performed, for example, loading screens, menu selection, and different levels or gameplay scenarios, you can annotate these regions in your game so that Performance Advisor can report data for them independently.
Performance budgeting
Because they have different performance expectations, it’s a good idea to set your own performance budgets for each device. For example, if you know the top frequency for the GPU in the device, and you have a target frame rate, you can calculate the absolute limit of GPU cost per frame.
GPU cost per frame = GPU top frequency / Target frame rate
When you generate a report with Performance Advisor, you can pass in your performance budgets, which are then shown in the charts, so you can easily see if you’ve broken one.
In the example below, we can see correlation between high numbers of execution engine cycles and drops in FPS. Performance Advisor tells us that the GPU is busy with arithmetic operations, and that the shaders could be too complex. The report provides a link to an advice page on the Arm Developer website, that explains how to reduce arithmetic load in shaders.
More charts include key performance metrics such as CPU cycles per frame and GPU bandwidth per frame, reported for read and write access. There are also charts showing the content workload , draw calls, primitives and pixels per frame, and the level of overdraw per pixel.
Download an example Performance Advisor report
Automated performance analysis
It’s far easier to fix problems as they arise than is it to patch problems later on. Performance Advisor’s key application performance metrics are useful to monitor over daily runs, to see how changes to your application affect performance during development.
Arm Mobile Studio Professional includes headless CI support - so you can easily deploy large-scale automated performance testing across multiple devices. Using a device farm with a CI workflow, you can generate performance data and optimization advice automatically, every night, for several Android devices. As you check in code, you can easily monitor how your content performs against your performance budgets over time, and raise alerts when you start to approach or break those budgets.
The Professional Edition also enables you to build bespoke data dashboards from the data that been collected. Performance Advisor's machine-readable JSON reports can be imported into any JSON-compatible database and visualization platform, such as the ELK stack. Compare metrics between test runs to quickly determine which changes impacted performance, and which type of workload is the likely cause for a regression. Query the data and compare performance against specific targets to identify optimization next steps.
Read more about how to integrate Arm Mobile Studio into a CI workflow on the Arm Developer website.
Resources
Arm publishes various resources on their developer website, to help you optimize performance:
Optimization advice – quick reference to help you avoid common problems. Mali best practices guide – comprehensive guide describing in detail how to ensure your content runs well on Mali GPUs. Developer guides such as those for Technical Artists, covering best practises for geometry, textures, materials and shaders. Download the Mali GPU datasheet to see the different features and capabilities of Arm Mali GPUs from the Midgard-based Mali-T720, to the latest Valhall-based Mali-G78. For detailed descriptions of all the performance counters you can analyze in each Mali GPU refer to the Mali GPU counter reference. Get Arm Mobile Studio
Arm Mobile Studio is free to use for interactive performance analysis. To use it headlessly in your CI workflow, you need an Arm Mobile Studio Professional license.

Testing on the newest OS is essential for all developers to ensure that their content, whether apps, games, or themes, is compatible and runs correctly. With the release of Android Q on Samsung devices right around the corner, we’ve created a handy guide to help developers install Android Q beta, so you can test your apps.
Know Your Options
The beta opens on October 21, so be sure to mark your calendar. It’s also important to note that the beta program is only for Galaxy flagship phones such as the Note10, S10, Note9, and S9.
Depending on your device and carrier, you may have different options for getting beta access. The following table shows the regions and carriers that will have access to the Q OS beta program.
If your device falls into one of these categories, you’re in luck! All you need to do is download the Samsung Members App from the Galaxy Store, and follow the registration instructions in the app. After you’re done, your phone updates automatically as soon as possible.
Country Carrier Beta Open (10/21) Korea SKC Open KTC Open LUC Open UNLOCKED Open US SPR Open TMB 7,500 registered users UNLOCKED Open UK UNLOCKED Open Germany UNLOCKED Open Poland UNLOCKED Open France UNLOCKED Open Spain UNLOCKED Open India UNLOCKED Open China UNLOCKED Open The beta is available for the carriers and countries shown above, but if you don’t fall into one of these categories or the beta program is full, what can you do?
Remote Testing
If you cannot update your own personal device, you’re not out of options just yet. We understand not everyone has access to a device that fits these requirements, so as such we are adding phones with the Q OS beta to the Remote Test Lab so that you may remotely test your apps and themes on real Samsung devices.
Testing is straightforward and easy on the Remote Test Lab, so you can head to the Remote Testing Lab (RTL) to start testing as soon as the beta version is publicly available.
