What should I do if the touch screen of my mobile phone fails?

I suggest you clean up the screen of your mobile phone first. Static electricity on the mobile phone screen may cause the touch screen to fail. At this time, you just need to gently wipe the whole screen with your hands.

Press the lock button several times.

Many times, the failure of mobile phone touch screen is due to slow response caused by software conflict or incompatibility, so it is possible to recover by pressing the lock button several times.

Shutdown restart

For more serious cases, you can turn it off and wait for a few minutes before turning it on.

Removing and reloading cards

Or take out the memory card and phone card of your mobile phone and try again in a few minutes.
