iPhone “ghost touch” — the screen tapping, swiping or typing by itself — is often caused by a cheap charger, a bad screen protector or a software glitch, all free to fix. Only a failed digitiser needs a replacement screen (from £18.66). Here's how to find the cause.
What causes iPhone ghost touch?
Direct answer: the most common causes, in order, are (1) a poor-quality or non-genuine charger sending electrical noise into the touch layer, (2) a cracked or cheap screen protector, (3) a temporary software glitch, and (4) a genuinely failing digitiser after a drop or water. Work through them cheapest-first.
Free fixes to try first
- Unplug the charger — if the phantom taps stop, the charger or cable is to blame. Use a genuine one.
- Remove the screen protector and case.
- Force restart: Volume Up, Volume Down, hold Side.
- Clean and dry the screen; grease and moisture cause phantom input.
- Update iOS to clear known touch bugs.
| Ghost touch happens when... | Cause | Fix |
|---|---|---|
| ...plugged into a charger | Cheap charger / cable | Use a genuine charger |
| ...with a cracked protector on | Screen protector | Remove it |
| ...randomly, after a drop or water | Failing digitiser | Replacement screen |
| ...only in one app | Software | Update / reinstall |
When it's the screen
If ghost touch continues off-charger, with no protector, after a restart — especially following a drop or water — the digitiser has failed and a replacement screen fixes it. Screens start at £18.66; choose your grade with our iPhone screen grades guide.
