Sleep/wake button not working, but screenshot and power off functions still work
I just recently updated my ipad 2 64gb wifi to ios 9.2.1 and when it powered on i noticed the top sleep/wake button would not turn off the screen. After some research i turned on the assistive touch and even when i try to lock the screen from that it wont lock. I have also tried to return to ios 8 but was unsuccessful.
need help tired of wait for the 2 min lock.
iPad 2, iOS 9.2.1
