Hello Everyone, I just got this phone and need some help. 1. How do you get the G- calibration to actually work, its on a level surface and it wont stay in the middle? Also, 2. how do you get the screen to turn when you turn your phone. Sometimes it does not turn and sometimes it takes 5-10 seconds. 3. Another thing, how do you set the phone tot turn off at night and back on without an app? if I need a app, which one is the best? thanks.
