Fix 'System UI Not Responding' on Android

Repeated System UI crashes, the causes (launcher, widgets, WebView) and their fixes.

'System UI isn't responding' means the interface layer itself, home screen, status bar, stalled. Usual suspects: a misbehaving widget, a third-party launcher or an outdated WebView.

  1. 1Tap 'Wait', then remove recently added widgets and live wallpapers.
  2. 2Update 'Android System WebView' and Chrome in the Play Store.
  3. 3Using a third-party launcher? Switch to the stock one to test.
  4. 4Clear System UI cache: Settings → Apps → show system → System UI → Storage → Clear cache.
  5. 5Wipe cache partition in Recovery if it keeps happening.
  6. 6Low RAM devices: reduce home screens, widgets and animations.

Tip: System UI crashes right after a system update usually settle after a couple of days of re-optimization, wipe the cache partition to accelerate that.
