1、 External reasons

① Charger data cable

When charging with a non original charger data cable, the voltage is unstable, which can cause the screen to malfunction and jump. It is recommended to disconnect and replace the charger data cable.

② Screen protector film

Poor quality tempered film may affect the touch effect. It is recommended to tear off the film and check if the sensitivity is restored.

③ Water or dirt on hands

You can try wiping the screen of your phone with a tissue to remove any oil stains that may cause touch drift.

④ There is static electricity present

Static electricity on mobile phones can also be uncontrollable. In this case, you can lock the screen and charge the phone for ten minutes to solve the problem.

2、 System reasons

① Software issues

Determine whether it is a certain software or all software fixed area touch failure. If a single software is not sensitive in that area, it may be due to software issues. If all software has the same location touch failure, it is a screen problem and needs to be repaired.

② Too many backend software

Opening the software in the background is likely to cause the mobile phone to get too laggy, and the screen is not sensitive. Try to close the background running software.

③ System issues

If there are many applications installed on the mobile system and the phone configuration is not high, it is easy to cause insufficient phone resources, so this phenomenon may also occur. It is recommended that you try to restore the factory settings or flash the phone.

④ Crash or false crash

It can be resolved by turning off the screen or restarting the phone.

3、 Screen related reasons

Touch failure caused by the screen itself: such as dropping the phone, loosening the LCD screen cable after liquid ingress, and corrosion of the touch IC. These hardware damages can cause the screen to drift and touch failure.

How about it, have you learned how to judge?

It should be noted that the hardware failure of the screen itself involves the repair of internal parts of the phone, which cannot be repaired by an individual. It is necessary to seek professional maintenance personnel for repair and replacement. Do not disassemble or repair it yourself to avoid losses.
