Nexus 4 screen regularly blacks out when make a call
The screen on my Nexus 4 regularly blacks out when I make a phone call. This has got worse since I had the screen replaced recently. I can hear the call but I cannot then use the screen to switch to speaker and worst of all I cannot disconnect the call. If I keep intermittently pressing the on/off button the screen will flash intermittently and if I keep hitting where the disconnect bar is I can after a while hit it just at the right time and I get my screen back. Nightmare! Is there a remedy to this fault?
