An unresponsive touch screen can be caused by anything from a simple software glitch to a faulty screen protector. Before heading to a repair shop, try these fixes.
Perform a Force Restart
Often, a system process freezes the UI. A force restart cuts power to the CPU for a second and clears the temporary memory.
Clean the Screen Thoroughly
Oil, moisture, or dirt on the screen can interfere with the capacitive touch sensors. Use a microfiber cloth and a tiny bit of distilled water.
Remove Screen Protector & Case
Sometimes the case is putting too much pressure on the edges of the screen, or a cracked screen protector is blocking the sensors.
Disconnect Charging Accessories
A faulty charger or cable can cause "Ghost Touch" or make the screen unresponsive due to improper grounding and electrical interference.
Enter Recovery Mode (Last Resort)
If the screen is still unresponsive, connect it to a computer to see if the hardware is detected. This helps confirm if it's a software or hardware failure.
