Is there a screen or way to see more detailed information about the charging of the S3? I've been having issues with my phone not charging. I've done a factory reset and bought 2 more OEM batteries with no help. I can plug the OEM wall charger into the phone and the phone states its charging. It actually looses charge some of the time. It's also sits motionless on a table and I hear the charging sound sound 3 or 4 times right in a row. The lock screen cycles between showing the phone is idle and then charging each time the phone sounds off. I suspect that the charging circuit in the phone is not working correctly. I'm wondering if there might be a debug or developer screen that will show if the phone is actually charging or not. As mentioned above, a lot of times the charging lightning bolt shows up on the battery and the lock screen states the phone is charging but it's actually loosing charge while the phone is idle (other times it's sitting idle and actually gains a charge). I'm thinking I'd have a tough time showing Tmobile or Samsung that the phone is defective... especially without giving up the phone for several days.
