Hey fellow Lumia owners, wondering if anyone else is experiencing the same problem as me. Just recently my phone starts freezing up whenever I make or take a phone call. As soon as I answer or hit call, the screen goes black and won't do anything. The call always works but the phone doesn't recover until the call is ended. This means I can't use speaker phone or even hang up a call, the other person always has to. As soon as the call is disconnected everything is back to normal... Kind of a weird problem, anyone got any advice?
Cheers

Had a similar issue where if I answered a call using Bluetooth, it would freeze and require. A reboot...

On my 900, a situation similar to yours would would happen randomly...

Make sure the proximity sensor is not covered.

Sounds like your proximity sensor has gone bad. Not sure there's a software fix for that.

Aha faulty proximity sensor does make sense cause ya that's what turns the screen on and off during the call. I'll have to take it in grrrr
