Okay, when I first got my phone, it was working perfectly. It's been a few weeks and fairly recently, my phone has decided that it will not go into landscape mode (for anything). Now, I have already made sure that the auto rotate function is selected, I have reset the phone, taken out the battery many times, I have restarted the phone, and etc... When I go into to the phone to re-calibrate it, every single time I try it says "calibration aborted" ... which I'm sure is why my phone won't rotate anymore. It would make complete sense. And YES the phone was laying flat on its back with the camera touching the flat surface... that is NOT the problem. I've pretty much had the same apps since before the problem started so what in the world could be wrong!?? Why won't my phone calibrate anymore? My other question is, if I can't fix it, and I really don't wanna have to order another phone and start over, is there an app or something that I can use to re-calibrate my phone instead of using the g-sensor so it will work?? I'm desperate. Thanks so much for any help!
