Last night I decided to reset my 930 as since updating to update 1 when I go from an app and press the windows key the start screen flashes up but with a stutter/skip. Reset my 930 but i then as to sign in and it tells me that I have no connection even though I had just tuned in the WiFi. I reset about 5 times and still the same each time so was unable to use any back up, then to my surprise I still have the stutter from the start screen. Has anyone else encountered these problems please or have any in site as to what it maybe?
