IPhone 6 screen freeze
I got a refurbished replacement from apple after my original phone died. I've noticed the display will lag or even freeze for a second or stay frozen until I press the off button. ive noticed it mostly happens when my case is on but it's the same case used on my other phone before the replacement. I tried to update the phone to resolve the problem but it did not help. is this happening with anyone else?
iPhone 6, iOS 9.3.5
