Screen light setting Galaxy A30

[FredNava]

I have some question 

My phone is Samsang Galaxy A30, I found some error , during a call some times screen light will not light up after it take out from ear

Is this a fault or can I control this in user setting. Please help me 

Thanks - Fredrick Navaratne

If you lock the screen manually during the call then you have to unlock it manually. Other then that no setting needed. It might be a bug.

thanks for reply but it happen in the regular way

Then it mag be issues with proximity sensor or it's calibration

don't block the proximity sensor placed above the notch during calls

run an auto device check in this app
auto check available in get help

or run LCD/hardware test use the code *#0*# in dial keypad

click sensor and there you'll see working of sensors available in your device
