Issue: Severe scrolling lag and UI stuttering after update
After updating my S21 FE to One UI 7, I am experiencing noticeable lag while scrolling through the UI — especially in system apps like Settings, Play Store, Gallery, and the app drawer. The overall responsiveness has dropped significantly.
I have already tried:
- Clearing cache partition via recovery
- Turning off all animations and setting them to 0.5x
- Disabling RAM Plus
- Wiping memory via Device Care
- Testing in Safe Mode (still laggy)
- Using a different launcher (Nova) — which reduces the lag
- Resetting all settings (without factory reset)
None of these worked. This issue did not exist on One UI 6.1, so it seems to be directly caused by the One UI 7 update. Please investigate and resolve this in a future patch. I'm happy to send logs for analysis.
