Touch not working after a screen replacement?
If your touchscreen stopped working, works only in parts, or touches by itself after a screen replacement, the cause is usually the part used or how it was fitted. Most of these problems can be corrected.

Signs you may notice
- Touch dead in parts of the screen
- Phone touches by itself (ghost touch)
- Touch works only after pressing hard
- Fingerprint sensor stopped working after the replacement
Safe checks to try first
- Remove any new screen protector and case.
- Restart the phone.
- Clean the screen and dry your hands; moisture causes false touches.
- Check whether the problem happens while charging only (a poor charger can cause ghost touch).
Stop and bring it in if…
- The screen is lifting at the edges
- Lines or patches appear on the display
- The phone gets warm near the screen
What usually causes it
One symptom can have several causes. These are the most common ones.
Low-quality replacement screen
Some cheap screens have poor touch layers.
Connector not seated
The touch or display connector wasn't fully pressed in.
Pinched flex cable
A cable damaged during reassembly.
Fingerprint needs recalibration
In-display sensors must be set up again after a new screen.
What our technicians do
We check the connector and cable first, test with a known-good screen, and recalibrate in-display fingerprint sensors where needed. If the fitted screen is faulty, we explain the options for a better-quality part.
