I've been using my new Lumia 928 for a week now and there's an issue that has driven me mad for the past days.
The phone touch interface stops responding properly with no apparent reason. I cant isolate the issue on a particular app, it just happens randomly.
The phone itself seems to keep running (if it happens when a call comes in, the phone keeps ringing but I cant answer it). The only solution I found so far is to reset the device (power + vol down).
The phone is new and I have only downloaded a handful of apps (the basics like Viber, Whatsapp, etc.)
I have googled around but found no answer so far. Has anyone had this issue? Is this a Windows Phone 8 known issue? right now I'm running the latest version (OS version: 8.0.10211.204, Firm revision: 1532.5957.1318.3021)
