1 After screen replacement iPhone screen randomly stops responding
After a screen replacement, the iPhone works fine for a while and then the digitizer just randomly stops functioning. However to my knowledge it can’t be a hardware issue since it is fixed temporarily by restarting the phone.
What kind of screen did you buy and where from? I would also recommend checking the LCD/ Digitizer connector on the board to make sure it's fully connected.

I agree with Ronan, I would also recommend you clean the connections with a qtip and alcohol. Make sure you disconnect the battery first.

@ronan0s I have no idea, it was just a screen that we had in stock. I will try your suggestion if the issue persists
