Galaxy A11

[Edgurr]

So I got this A11 phone in July, and my screen does not sleep, not even when I use the power button the screen just locks and the USB connector always flickers, the screen only turns off when I charge it

I have the same problem with my S20 ultra

This has begun with mine just today, have you been able to find the solution?
