Well, I have a possible issue that is probably not going to be remedied.
About a month ago (before I bought the awesome Diztronic TPU case) I got up early one morning for work and fumbled around and dropped my GNEX on my hardwood floors. Thankfully it didn't break but the back cover and battery flew out.
Ever since then I think my screen rotation has actually been even worse. It often flips upside down when I'm holding it vertically in one had at a slight angle for normal reading. Generally it corrects itself after 2-3 seconds, but it is annoying.
I swear this happened after I dropped the phone, but I can't be 100% positive that is the case. It generally did have a slow auto rotate to begin with, but I don't remember it getting it's bearings just flat out wrong. These are two different issues and is why I don't feel I'm being paranoid.
Is this a possible thing to damage from dropping? Is it the accelerometer that is messed up?
