1. The screen is not sensitive due to the unclean screen.

Dirt or water stains on the screen can create loops on the screen and affect the touchscreen effect.

Solution: Use a clean dust-free cloth to wipe the dirt and water stains on the phone.

Second, the mobile phone has a film.

If the film is too thick and there are air bubbles, the touch screen may not be sensitive.

Solution: Remove the film and then use it for observation, and you can replace it with a new one.

3. When charging, the screen is not sensitive.

When using the mobile phone while charging, there may be situations such as unstable voltage, static electricity on the mobile phone, etc., resulting in less sensitive operation.

Solution: Use the original charger to charge the phone; Or try to change to a grounded socket while charging. Also, try not to use your phone while charging.

Fourth, the screen fails due to insufficient running memory.

Solution: Call up the background running software, and speed up the background cleaning with one click; Restart your phone.

5. Temporary screen failure caused by static electricity in the mobile phone.

When the mobile phone is taken out of the pocket or bag, no matter how much you swipe the screen, it does not respond, because the mobile phone rubs against objects in a dry environment, which causes static electricity on the screen, resulting in temporary touch failure.

Solution: Wipe the screen with a drisome damp cloth several times to remove static electricity, and wash your hands and dry them before operating the phone.
