Hey guys, I have a 5s which seems to have a weird stutter effect when the parallex is on. It's particularly noticeable when you unlock the phone and go to the home screen, the icons and background lags/stutters briefly. I have an iPad mini and iPhone 5 and haven't seen this issue on those devices. Anyone else seen this? I'm wondering if it's worth returning the phone for, it may be an accelerometer hardware issue or could be software.
