Launcher restarts or redraws after leaving an app: what to check usually has more than one possible cause. Treat it as an Android Home-app problem first, then a launcher-specific problem.

Reproduce the problem cleanly

Restart the phone, open Home, and repeat the action that fails. Note whether it happens every time, only after heavy multitasking, only after reboot, or only with a certain widget or gesture.

Check these in order

  1. Confirm the intended launcher is still the default Home app.
  2. Update the launcher and Android system components.
  3. Check battery optimization if the launcher is being killed and redrawn.
  4. Remove one problematic widget, icon pack, gesture, or live wallpaper temporarily.
  5. Test the stock launcher. If the same problem happens there, the launcher may not be the cause.

Do not clear data before you have a backup

Clearing launcher storage can remove layout settings. Export or screenshot the layout first. Reinstalling should be a later step, not the first reflex.

Know the safe exit

If Home becomes unusable, open Android Settings from Quick Settings, go to Default apps, and switch to the stock launcher. You can troubleshoot the third-party launcher without being trapped on it.

Minimalistic is one example of a third-party Home app. The same switching rule applies to any launcher: keep the stock launcher installed, make one change at a time, and know the path back to Android’s default-app settings before you start.

Most likely causes

Android may be reclaiming launcher memory, aggressive battery management may be killing the process, or the launcher may be rebuilding after an update.

Fix it in this order

  • Reboot once and reproduce the issue before clearing data.
  • Check the phone’s battery/background restrictions for the launcher.
  • Reduce unusually heavy live widgets/wallpapers temporarily.
  • Update both Android and the launcher, then test again.
  • Export/backup the layout before clearing launcher storage.

Do not clear launcher data as the first step. That can erase the layout and hide the original cause.
