Fix it: step by step
1. Back up before anything elseiCloud ▸ Back Up Now, or Finder ▸ Back Up Now. Never skip this. 1 min
2. Force-restart the deviceThe unstick fix: Volume Up, Volume Down, then hold Side button until the logo. 1 min
3. Check the obvious settings pathMost of these symptoms are one toggle deep — walk the exact path in this guide. 1 min
4. Update iOS and the affected appHalf of all bugs are already fixed in the newest point release. 1 min
5. Reset the affected subsystemNetwork, Keyboard Dictionary or Home layout — scoped resets only. 1 min
6. Last resort: full erase & restoreOnly after the backup in Step 1 is verified. DFU restore, not drag-and-drop. 1 min
Prevent it next time
- Keep iOS and your apps up to date — half of these bugs are fixed in point releases.
- Install major updates at night while charging, so background work finishes while you sleep.
- Restart your iPhone once a week; it clears temp caches that slowly build up.
If that didn't work
Escalate in this order — never skip straight to the erase:
- Re-run the earlier steps with the reset & restore subsystem fully reset (scoped reset, not erase).
- Check Apple System Status — activation, backup and update outages mimic hardware faults.
- Open the Problem Finder from the dock and answer with “All the time” — it re-ranks guides for chronic cases.
- Book diagnostics with the timeline from your ticked steps; technicians read the order you tried.
