My wife texted me late this afternoon to tell me my youngest daughters phone was crashing. I came home and spent the last hour and a half working on it. I finally was able to do a restore and reload her stuff from iCloud. It’s charging now but seems to be working. We just bought that phone last August. If this doesn’t do the trick then I’ll have to take her to the store tomorrow to see what they’ll do since it’s still under warranty.
