4.1 didn't fix anything for me. Worthless.
Downgrading to 4.0.2. Hope this stupid battery drain + proximity sensor is really fixed in the next update whenever that comes!
EDIT: This is BS!! I never knew you CAN'T downgrade firmwares officially! Gives me some warning message saying device is not eligible for this build! So does that mean we're locked in 4.1?!?
