I have just had my phone for 2 days and before I could turn off the accelerometer I noticed an issue .....when I was in the settings menus I accidentally tilted the phone sideways and it went into landscape mode so I titled it back and everything was fine then after that I had titled it again on accident and when I tired correcting it , it would not go back to portrait mode I was still able to scroll in landscape but the only way I could fix it was to go bak to the homescreen and go bak into settings then it would just happen again......also when charging the phone it would lag when I would unlock it ( I'm using the slide your finger passcode to unlock)
