the new 30 second timer works correctly. It will dim after 20 seconds and lock at 30. However the 1 or 2 minute does not, time is actually cut in half. I always have had 1 minute auto-lock but since updated to iOS 9 I noticed the screen shut off rather quickly than normal. I used the clock on the home screen to verify and the 1 minute auto-lock, locks after 30 seconds. The 2 minute locks at 1 minute. I did not try any other time after that. Does anyone else have this issue?
