Android System UI Not Responding – How to Fix
If your Android phone suddenly freezes or shows a “System UI isn’t responding” message, you’re not alone. This issue usually appears after updates, app crashes, or system cache corruption, and it can make your phone almost unusable.
Below are proven fixes that work on Samsung, Pixel, Xiaomi, and most Android 13–15 devices.
1. Restart Your Phone
A forced restart clears temporary system glitches that often trigger System UI errors.
2. Clear System UI Cache
Corrupted cache data is one of the most common causes.
- Settings → Apps → System UI
- Storage → Clear cache
3. Update Android System WebView
Outdated WebView versions frequently break System UI rendering.
4. Remove Recently Installed Apps
Apps with overlay permissions or poor optimization can conflict with System UI.
5. Boot into Safe Mode
Safe Mode helps confirm whether a third-party app is causing the issue.
6. Reset App Preferences
This restores default system app behavior without deleting data.
7. Last Resort: Factory Reset
Only use this if nothing else works, and back up your data first.
