UI 9 Camera Bugs

This is a report and a query regarding UI 9 software camera bugs for the S25 Ultra.
I made a query of Gemini.ai with the following question:
"I have a Samsung s25 Ultra with the updated UI9. After updating to UI9 I did a video of an evening performance (lower lighting but adequate) of a concert. The following problems were observed:

1 -- Consistently, the lighting control would not hold and reverted back to a darker level.

2 -- The video function would drop and default to photo, completely wiping out a segment of the concert.

3 -- On a couple of occasions during the video shoot, the entire camera function quit, and I had to restart the app.

4 -- The magnification was difficult to maintain.

Why is this happening? Previous UI versions worked well. It seems that it was only after installing UI9 that this issue started."

HERE IS GEMINI'S REPLY:

The behaviors you experienced during the concert are a combination of software bugs introduced in the major One UI 9 update alongside system protection mechanisms triggered during intensive video recording.

Major OS updates overhaul the underlying camera pipelines, image signal processing (ISP), and thermal management algorithms, which can cause unexpected glitches until post-update patch fixes are released.

Why These Specific Problems Occurred

1. Lighting Control Reverting to Darker Levels

• Auto-Exposure & HDR recalibration: One UI 9 updated the auto-exposure logic in low-light environments. When shooting a concert with high-contrast stage lighting, the app's auto-exposure metering frequently recalculates dark backgrounds versus bright stage lights and overrides manual exposure lock tap-adjustments.

• Thermal throttling (Dimming): Continuous high-resolution video recording generates heat. To prevent overheating, One UI 9’s thermal daemon automatically reduces processor clock speeds and screen brightness, which often forces the sensor preview and recording pipeline into lower power, darker exposure states.

2. Video Dropping and Switching to Photo Mode

• App State Crash / Memory Overload: In One UI 9, a known background process bug causes the Camera app’s video recording thread to crash when RAM pressure spikes or frame buffers drop. When the video thread fails mid-recording, the camera service force-reloads its default launch state (which is standard Photo Mode), causing the app to silently drop out of video mode and discard the unsaved buffer.

3. Camera App Crashing Completely

• System Service Timeout: Low-light processing paired with real-time digital/optical zoom switching places heavy computational stress on the NPU and ISP. Under One UI 9, unresolved memory leaks or camera daemon timeouts (cameraserver crashing in the background) cause the main app process to terminate entirely, requiring a full app restart.

4. Difficulty Maintaining Magnification

• Lens Switching Logic Bug: The S25 Ultra uses multiple physical lenses (1x, 3x, 5x, etc.). In low-light environments under One UI 9, the system repeatedly hesitates between switching to the physical telephoto lens or using digital crop on the main sensor. This "lens-hopping" leads to jerky zoom jumps, focal resets, or difficulty maintaining a locked magnification level.
  -----------------------------------
  Subsequently, I contact Samsung support and ultimately told to do a "settings reset".  Consequently, I asked Gemini once again about using this as a fix, asking, "Samsung informed me to do a "settings reset" and that usually corrects the camera issues. Is this correct?"
  
  Gemini's Reply:
  

  Yes, Samsung’s recommendation is partially correct, but it is only a temporary fix for part of the problem.

  Resetting your camera settings (or clearing the Camera app’s data) is standard Tier-1 tech support troubleshooting. It helps resolve isolated glitches, but it will not permanently fix core OS bugs introduced by major software updates.
  
  

  What a "Settings Reset" Will (and Won't) Do

  What it WILL fix:

  • Corrupted Preference Profiles: During major updates (like One UI 9), pre-existing camera config files can become mismatched with the new OS code. Resetting restores default preferences, which can stop immediate app crashes or UI freezes caused by bad configuration values.

  • Stuck Settings: If an internal toggle (like auto-exposure, tracking auto-focus, or dynamic FPS) became stuck in an invalid state during the update, a reset forces those features back to factory defaults.

  What it WON'T fix:

  • Background OS / Memory Leak Bugs: The issue where video drops and defaults back to photo mode, or where the camera app crashes entirely, is usually caused by a system-level memory or daemon crash (crameraserver) in One UI 9. Resetting camera settings does not fix underlying system software bugs.

  • Low-Light exposure and lens-switching algorithms: The way One UI 9 handles exposure metering and zoom switching under dynamic stage lighting is hardcoded into the OS firmware update. A settings reset won't alter the underlying image signal processing (ISP) code.

  
  THE QUESTION IS:

  When will Samsung get UI 9 fixed?
