What s the deal with the occasional Android phone screen failure?

The screen of the current touch screen mobile phone is divided into two parts in terms of physical structure, one is responsible for the LCD screen of the screen display, and the other is the touch control module responsible for feedback of touch information. Judging from your situation, there should be nothing wrong with the LCD screen itself, but the touch module may be faulty. There are two possible faults, one is that the touch module itself has a hardware problem and needs to be replaced; Another possibility is that the cable between your phone's touch module and the LCD screen is loose.

What to do if the touch screen of the mobile phone fails.

This kind of fault is more difficult to troubleshoot personally, it is recommended that you find a more regular mobile phone repair point for inspection. If the cable is loose, it can be solved by re-inserting it after disassembly, even if the touch module is broken, it will not be too expensive to replace one. But if the maintenance point is alarmist, saying that the entire LCD screen needs to be replaced, then you have to be careful, it may replace your good LCD screen with a second-hand one, you must be careful.
