Hello Samsung / Tizen Technical Support Team,
We are observing a playback issue on Samsung Tizen TVs when streaming DRM-protected content that uses a multi-key DRM configuration. We would like to report the issue and request assistance in investigating the behavior on Samsung devices.
DRM Provider: Castlabs
DRM Type: Widevine
Streaming Format: MPEG-DASH (MPD)
Player Environment: Samsung Tizen Application using the Samsung AVPlay / native playback stack.
Content DRM Configuration:
Our content is packaged with a multi-key DRM setup, where different resolution groups use different encryption keys:
Key 1: 360p, 480p, 720p
Key 2: 1080p, 4K
Observed Issue:
Playback starts normally and the video plays correctly at the initial resolution. However, when the adaptive bitrate algorithm triggers a resolution change that requires switching DRM keys, playback fails.
Specifically, the issue occurs in the following scenarios:
When switching from 720p → 1080p or higher
When switching from 1080p → 720p or lower In both cases, the switch requires a DRM key change, and the playback fails shortly after the transition.
Additional Observations:
If we modify the MPD to limit playback to only one key group (for example, only up to 720p or only 1080p and above), playback works correctly without any interruption.
The issue appears only when the player needs to switch between representations encrypted with different keys.
Playback works correctly on other platforms using the same MPD and DRM configuration.
The issue appears specific to Samsung Tizen playback behavior during multi-key DRM key transitions. Device Details (Example Device Where Issue Was Observed):
Model Code: UA32T4380AKXXL Software Version: T-KTS2UABC-2700.6 Platform: Samsung Tizen TV Error Behavior:
Video plays normally for some time and then fails after a resolution change requiring key switch. In some cases playback stops after ~20–30 seconds when adaptive bitrate switching occurs. Request:
Could you please confirm:
Whether multi-key DRM streams with adaptive bitrate switching across keys are fully supported on Samsung Tizen TVs.
If there are specific packaging or DRM license configuration requirements for multi-key playback.
Whether there are known limitations in AVPlay or Tizen DRM handling related to key switching during DASH adaptive playback. We would appreciate any guidance or debugging steps that could help identify the root cause of this issue.
Device Details:
Test Labs Device: Korea (Suwon-TV), NEO QLED 4K, QN55QN80F(2025), Tizen 9.0, QN55QN80FAFXZA
Actual TV: UA32T4380AKXXL (Model Number)

The Galaxy Watch ecosystem is designed for seamless connection from capturing screenshots that sync automatically to your phone, to sharing what's on your wrist in seconds. This works great for most users.
However, if you’re a developer, tester, or creator who prefers working directly on a computer, there’s a more efficient, hands-on way to capture your Galaxy Watch’s display.
Using Command Prompt (or Windows Terminal) and Android Debug Bridge (ADB), you can directly screen record or capture screenshots from your Galaxy Watch without needing a companion mobile device or any third-party apps. It’s fast, simple, and perfect for creating app demos, tutorials, or development documentation.
Record your Galaxy Watch screen via ADB
Follow these steps to record your Galaxy Watch screen directly from your computer:
Open the Command Prompt and use the cd command to navigate to the platform-tools folder: cd %LocalAppData%/Android/Sdk/platform-tools
Pair and connect your Galaxy Watch to your computer over Wi-Fi. NoteThe link directs you to steps on how to connect the Galaxy Watch to Android Studio, but you can follow the same steps and commands when using the Command Prompt. Enter the command below to start screen recording your watch: adb shell screenrecord /sdcard/record_demo.mp4
This command tells your computer (via ADB) to start recording the screen of your connected Galaxy Watch. Let's break it down piece-by-piece:
adb – connects your computer to the watch or Android device. shell – opens a command-line interface inside the device. screenrecord – starts recording the device's screen. When you run screenrecord, the device starts capturing the display and saves it as a video file (the default format is .mp4). /sdcard/record_demo.mp4 – sets the file path where the recording will be saved on the device and the file name. Stop the recording by pressing CTRL + C.
Transfer the recorded video to your computer: adb pull /sdcard/record_demo.mp4 C:\Destination\Folder\In\Your_Computer
The pull command copies the recording from your watch to your computer.
(Optional) Delete the recording from your watch using the rm command. adb shell rm /sdcard/record_demo.mp4 You now have a recorded video of your Galaxy Watch screen saved directly on your PC, ready for editing or presentation.
Capture screenshots directly from Galaxy Watch to PC
If you only need static images, you can easily transfer screenshots from your Galaxy Watch without using a phone:
Take a screenshot on your Galaxy Watch by pressing the Home and Back buttons simultaneously until you see the screenshot animation.
Locate the screenshot file using ADB shell and copy its filename.
adb shell cd sdcard/DCIM/screenshots ls
NoteYou can also run the simplified version of this command:
adb shell ls /sdcard/DCIM/screenshots/ The ls command lists the screenshots stored on your watch.
Transfer the screenshot to your computer: adb pull /sdcard/DCIM/screenshots/[File_Name].png C:\Destination\Folder\In\Your_Computer
The image is now available on your computer for quick viewing or editing.
Things to keep in mind
This method works best with Galaxy Watches running Wear OS powered by Samsung (Galaxy Watch4 and newer models), as these devices support ADB connections for development and debugging. While this approach is highly effective for capturing screen activity, it has some limitations:
Audio Capture: The screenrecord command records video but does not capture system audio. If you need audio, additional steps or tools may be required. Recording Duration: The recording duration may be limited (typically up to 3 minutes). This restriction can vary depending on the device and ADB implementation. Compatibility: Older Tizen-based Galaxy Watches may not support ADB connections, making this method unsuitable for those devices. Using ADB through Command Prompt provides a direct and efficient way to interact with your Galaxy Watch. Whether you're developing apps, recording demos, or capturing visuals for documentation, these simple commands make it easy to manage your device directly from your computer.

I’m still dealing with persistent UI lag and bugs on my Samsung S95B, and I’m surprised this issue continues even this year with brand new firmware 1661 and resets.
Symptoms:
Menu interface is slow and laggy, especially in Settings and Home screen.
Scrolling causes stutters or jumps/skips lines in some menus.
Delays when switching inputs, opening apps, or using Smart Hub.
UI gradually becomes less responsive the longer the TV stays on.
What I’ve tried (none of these solved it):
Updated to firmware
Multiple cold boots (hold power button until restart)
Smart Hub reset
Disabled TV Plus, Autorun content, ad services, autoplay previews, etc.
Clean install with only core apps
Factory reset → works for a few days then problem returns
Disconect internet
Only “solution” that works (but temporarily):
Using “Device Care > Memory Cleanup”
It improves UI performance significantly...
BUT only for couple hours
After that, lag and line skipping come back just like before.
So far, this is the only reliable way to temporarily fix the sluggish interface.
Likely cause (based on community feedback):
Tizen OS memory mismanagement (leaks, poor RAM recycling, app bloat)
Possibly related to ad-driven Smart Hub tiles or unoptimized background services
UI lag happens even with no streaming apps open and minimal setup
What I’m asking the community:
Has anyone found a real permanent fix????
Any way to disable Smart Hub completely or force a minimal launcher?
Anyone rollback to a more stable firmware (e.g. 1304, 1430) and fixed this?
Did anyone get Samsung to acknowledge or repair it under warranty?
It’s frustrating to have a flagship OLED 2500$ USD with incredible picture quality, but an TIZEN OS that feels like it’s choking on basic tasks. Hoping for any solutions beyond daily memory cleaning.
On my opinion this is a bad memory using that cause this. Memory because saturated over time.
In all case, Tizen team should redo their homework ASAP.
