My iPhone 5 froze in Safari while I was responding to another post on here. It was lagging horribly while I was typing. Then it froze and the last letter I typed was stuck popped up and kept flashing gray and the signal, time, and battery indicators kept disappearing at the same time. I had to hard restart. Tried to get some screenshots but they were just black. Running 7.1 with Verizon. It's also frozen in calls. Resetting network settings seemed to fix it. Anyone else have this happen? I know there's another post with an iPhone 4, but it's not running 7.1.
