If your Samsung Galaxy A15 touch screen has stopped responding — fully or in patches — it's usually either a temporary software glitch or a failed digitiser, and telling them apart takes two minutes. If the touch layer has physically failed, a replacement screen from £26.77 restores it. Here's how to diagnose it.
Try these first (free)
- Restart the phone (or force restart: Power + Volume Down for 10–20 seconds) to clear a frozen touch layer.
- Remove the screen protector and case — a thick or cracked protector can block touch.
- Dry your hands and the screen; moisture causes erratic or ghost touch.
- Boot into Safe Mode — if touch works there, an app is the cause, not the screen.
Is it the digitiser? How to tell
| Symptom | Likely cause | Fix |
|---|---|---|
| Dead touch after a drop or crack | Failed digitiser (glass/touch layer) | Replacement screen |
| Touch dead in one area / stripe | Damaged digitiser zone | Replacement screen |
| Ghost taps, phantom touches | Digitiser fault or moisture | Dry first; else replace |
| Touch stops only in one app | Software | Update / reinstall app |
Direct answer: if the touch failed after a drop, is dead in a fixed area, or produces phantom taps that a restart and drying don't fix, the digitiser has failed and a new screen assembly resolves it.
The replacement screen you need
The touch layer (digitiser) is bonded into the display, so it's replaced as one assembly. Fit an A15 OLED screen with frame from £26.77, or an original LCD assembly (4G / 5G). Note the A15's in-display fingerprint needs an OLED panel to keep working. See OLED vs LCD for the A15.

Frequently asked questions
Why is my Galaxy A15 touch screen not working?
Either a software glitch (fixed by a restart) or a failed digitiser after a drop. If restarting and removing the protector don't help, the touch layer has failed.
Can I fix A15 touch without replacing the screen?
If it's software, yes — restart, update, or test in Safe Mode. If the digitiser is physically damaged, the screen assembly must be replaced.
How much is an A15 screen with digitiser?
From £26.77 for an OLED-with-frame assembly; the digitiser is included as part of the screen.
