https://www.theregister.co.uk/2018/06/18/pixel_2_call_display_narcolepsy/ > Some Pixel 2 owners are still waiting for a fix for dead screens six months after the issue was first reported. > The display turns off during a phone call and – like Rip Van Winkle – can't be woken up. The bug began to manifest itself with the 8.1 Oreo update last last year – see here and here. Google support advised some owners to remove the screen protector and clean the proximity sensor, but this didn't do the trick.
