Launcher looks blurry or low resolution: display and wallpaper checks 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
- Confirm the intended launcher is still the default Home app.
- Update the launcher and Android system components.
- Check battery optimization if the launcher is being killed and redrawn.
- Remove one problematic widget, icon pack, gesture, or live wallpaper temporarily.
- 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.
Migration rule: change one layer at a time
First set the launcher as Home and test navigation. Then add favorites, then widgets, then icon pack, then gestures, then focus/hidden-app rules. Keep the stock launcher installed until the new setup survives a reboot and a normal day.
