1. If I move the headset plug slightly, it will think I have unplugged it entirely, thus triggering the pause of a video if one is playing. I haven't tested this since I've rooted, though I don't think it makes a difference.
2. When using earbuds (well, at least just this one pair, the only pair I could ever find) one of the earbuds (I forget which one. Again, haven't tested it since root, and don't think it woukd be different) made this rattling noise when certain frequency (I believe so. Kinda like speakers that can't process certain sound so they vibrate) sounds played (deep, I think). I think this may just have been a problem with the headphones.
On a side note another thing with my Nook is that I didn't back it up originally when I rooted it with CWM an CM10.1. I still had my personal files after setting up the root, though. Also when it boots up it looks like this https://www.youtube.com/watch?v=GSXxrvE1Ex0&t=5m40s (no, I don't speak... whatever that language is). Could any of this have contributed to this issue?
