Finally setup the new iPhone 7 yesterday. Set it up as new, no restore. While playing with it, though I can't remember what I was doing, iOS crashed (i.e. black screen, spinning wheel, back to lock screen). This morning it happened again. What preceded it though was that I had just unlocked the phone and I couldn't open any folders whatsoever. It was very strange. I was on the verge of rebooting it when it crashed. Anyone else experience this?
