Hello, has anyone else had issues where there iPhone 5s is at maximum brightness and suddenly it will noticeably drop to a lower one? I know the first reaction is the auto brightness option. But I always have that off. Always. I've never used it nor liked it very much. Nontheless it's happened quite a few times, and it's particularly painful during the day at times. I'll even adjust the brightness bar back to low and back to high again but it never hits the brightness it was noticeably at to begin with. Anyways, has anyone ever had this problem before? Thanks!
