If your iPhone touch screen has stopped responding, most cases are fixed for free — by a force restart, removing a bad screen protector, or unplugging a cheap charger — and only a failed digitiser needs a replacement screen (from £18.66). Here's how to work through it fast.
Try these first (free)
- Force restart: Volume Up, Volume Down, then hold the Side button until the Apple logo appears.
- Remove the screen protector and case — a thick, cracked or cheap protector is a very common cause of dead or laggy touch.
- Unplug the charger: a poor-quality or non-MFi charger can cause the touch layer to stop responding while plugged in. Try a genuine charger.
- Dry your hands and the screen; moisture triggers erratic touch.
Is it the digitiser? How to tell
| Symptom | Likely cause | Fix |
|---|---|---|
| Dead touch after a drop or crack | Failed digitiser | Replacement screen |
| Touch dead in a band or one area | Damaged digitiser zone | Replacement screen |
| Touch fails only while charging | Bad charger / cable | Use a genuine charger |
| Touch laggy with a thick protector | Screen protector | Remove protector |
| Touch dead only in one app | Software | Update / reinstall app |
Direct answer: if touch failed after a drop, is dead in a fixed area, and a restart, protector removal and genuine charger don't help, the digitiser has failed — replaced as part of the screen assembly.
The replacement screen you need
The touch layer (digitiser) is bonded into the display, so it's replaced as one unit. Screens start at £18.66 (iPhone 15 incell), with OLED options like the iPhone 15 Pro hard-OLED at £54.27. See our iPhone screen grades guide to pick the right one.

Frequently asked questions
Why is my iPhone touch screen not working?
Usually a software glitch, a bad screen protector, or a cheap charger — all free to fix. If touch failed after a drop and none of those help, the digitiser has failed and the screen needs replacing.
Can a charger cause iPhone touch problems?
Yes — a poor-quality or non-genuine charger can make the touch layer stop responding while plugged in. Switch to a genuine charger to test.
How much is an iPhone screen with digitiser?
From £18.66 for an incell display; the digitiser is included as part of the screen.
