I've tried quite a few things and cannot figure out why when I try to use flipboard on my gn3 it freezes up; and won't let me use it. Most of the time, but not all the time, when I try to read an article it will go to a black screen; and my whole phone will practically freeze up. However I can drag the notification bar down and go into settings, then hit the home button and it's fine or It will eventually say flipboard stopped unexpectedly can anyone tell me why this is happening? Is this a known problem?
