Symptoms
- No visible crack but touch does nothing
- Display may still show images normally
- Happened immediately after a drop
- May work briefly then stop again
Likely causes
- CommonLoosened display connector from impact shockThe force of a drop can jar a cable loose even without breaking the glass.
- CommonCracked digitizer layer under intact glassThe touch sensor can crack separately from the visible top glass.
- PossibleInternal component shifted and is pressing on the display boardA hard impact can move internal parts enough to interfere with the screen circuit.
What to do
- Force restart the phone to rule out a temporary crash triggered by the impact.
- Gently tap around the edges (without pressing hard) to see if touch flickers back briefly, which would suggest a loose connector.
- Avoid squeezing or flexing the phone further.
- Connect to a computer to attempt a data backup if the phone is recognized.
- Note the exact moment and severity of the drop for the technician.
- Get a diagnostic at a repair shop rather than guessing, since the fix (reseating a cable vs. replacing a digitizer) varies.
