Lumia 930 & technical preview

[EvEr34]

I have this ongoing issue with screen freezing up and not being able to hang up a call. I've hard reset and it's ok for a couple days but the issue comes back. Any ideas?

Just a technical preview. It'll probably be fixed with the new build (supposedly coming out in a few days) but it might not be too. If it becomes too much you could always revert back to Windows Phone 8.1.
