This morning when trying to use my Iphone 5s, the following happened. Pushed the home screen to wake of the phone to unlock, when I tried to swipe right nothing happened for a bit, and then home screen came up but all the icons were so huge you only saw like maybe 1/8 of the screen and couldn't move them around to access all of them. Finally as a last resort I did a hard reset,by pushing and holding both home and power buttuns. When I powered the phone back up, all seemed ok. What say you, is this a hardware issue, or an IOS 9.3 issue? Hope it was a one time experience. Phone is out of warranty.
