I have a Huawei P20 Lite
usually (as with most phones) when I have an incoming call the phone rings and a screen appears showing the number with the red reject button and green accept button.
Overnight this had disappeared. When I had an incoming call this morning, the phone rand and vibrated but the screen was blank. I put in my pin and went to the home screen, there was still no option to accept the call.
Does anybody know if this is a setting issue ? I have re started the phone a couple of times and turned it off for 30 mins but nothing has changed.
