The touch screen stops working after the screen turns off, how to fix it?

Question

Android

I have a Chinese Umi super after replacing the display with a touch screen. The touch screen works fine. But until the moment the screen turns off, whether it's a button or a light sensor during a phone call. After that, the touch screen stops working at all. Although the phone does not hang up and continues to work normally, it receives calls, the network is working. Hard buttons also work. How to fix?

Answer 1

Enable touch display and see if it shows it after releasing the lock. You can try to reflash the phone, as an option.
If possible, it would be nice to throw another module. And if they did not change it themselves, but in the service, then under warranty.
