Symptoms
- Random colored specks or noise covering part or all of the screen
- Pattern may shift when you move or flex the phone
- Touch may still work underneath the noise
- Often follows a drop or appears with age
Likely causes
- CommonFailing display panelInternal damage to the screen's driver circuitry can produce random noise patterns.
- CommonLoose or damaged display connectorA poor connection can cause the display to receive corrupted signal data.
- PossiblePhysical impact damageA drop can damage the display panel's internal circuitry even without cracking the glass.
What to do
- Restart the phone to see if the noise clears, since a corrupted display buffer can occasionally reset.
- Gently press near the edges of the screen to see if the pattern changes, which suggests a loose connector.
- Avoid pressing directly on the noisy area.
- Back up your data promptly since this usually indicates the display will continue to degrade.
- Note if the noise appeared after a drop, a repair, or gradually over time.
