Question: iOS 11 system freeze
iPhone 7 128 gig ram, 56% full
System will freeze and not be responsive except for a phone off reboot. I have tried doing a backup restore and a wipe/restore and it has not helped at all.
Local Apple Store has NO idea and they don't have any true diagnostics for the iPhone 7 to find out what is going wrong.
iPhone 7, iOS 11.1
