Black screen if I press the power key

[piterconlai]

Hi everyone .

I am having a problem after installing any ROM

In detail, the screen remains black if I press the power key and it seems to flash

I have to restart the phone to see the screen again

This problem does not appear when I install Stock ROM 9.0.6

Can you please help me ?

Install an application that can call the power off function programmatically, such as Button Savior.
This will get you closer to knowing the cause of the problem.

Installare un'applicazione in grado di chiamare la funzione di spegnimento a livello di codice, ad esempio Button Savior .
Questo ti avvicinerà alla conoscenza della causa del problema.

Hi, I installed the app, now what should I do?

Launch the application and grant it permissions. A small icon will appear on the side edge. Touch it. A mini menu will expand. Touch and hold the Power icon for a long moment. If you get a call to the system menu to turn off the phone without blanking the screen, then you have a hardware problem with the Power button, which perhaps responds to pressing the button several times instead of once.

Hello,
Could you perhaps have an idea to this issue please ?
