Symptoms
- Apps open by themselves
- Cursor jumps or types on its own
- Screen scrolls or swipes without you touching it
- Worse while charging or in certain corners
Likely causes
- CommonCheap or bubbled screen protectorAir gaps or poor adhesion can register as false touches.
- CommonCharging cable or charger interferenceA damaged cable or uncertified charger can introduce electrical noise that the screen misreads as touch.
- CommonMoisture or dirt on the screen or in the charging portLiquid conducts and can trigger the capacitive sensor.
- PossibleCracked digitizer from a dropPhysical damage to the touch layer can cause random false signals.
- Less commonSoftware bug after an updateOccasionally a firmware glitch causes erratic touch until it's patched or the phone is restarted.
What to do
- Unplug the phone and see if the ghost touches stop; if so, the cable or charger is the likely cause.
- Remove the screen protector and case, clean the screen with a dry microfiber cloth, and retest.
- Dry the charging port and screen edges fully if the phone was near water or humidity.
- Restart the phone to clear any temporary software glitch.
- Try a different, certified charging cable and wall adapter.
- Check for a pending software update and install it.
- If ghost touches persist with nothing plugged in and a clean bare screen, suspect digitizer damage, especially after a drop.
