Well, i was using my recently purchased Ipad 4 (Aug 3rd). And, like I always do, i open up Spotify, turn on some radio and browse some Reddit on AlienBlue. Sometimes if I don't like a song being played I use the 4 finger swipe to access Spotify quickly, and change it. but for some reason when i went to go and swipe it locked up for a quick second, and went to the Apple logo for maybe 4 seconds, Then returned to my homescreen, but the screen was a lot darker then i remember setting it, I go and check my brightness and it's at the halfway mark, so like 45 - 50% brightness. i tap the brightness toggle and it reverts back to the actual brightness it was set at previously. I went to check my usage since i was trying to get some good battery life out of it and for some reason, it's just showing a " - " on both on/standby parts. even though i was at about 11 hours on each thing. Sorry if this is hard to read, but it's my first time owning an ipad and I just want to make sure I don't have to return it, i mean I'm still in the 14 day return / exchange window so I could do an exchange for a fresh unit.
