Motion detector, auto-rotate failed on my new LG Spectrum 2

view story

http://forums.androidcentral.com – So FedEx delivered my new Spectrum 2 from Verizon yesterday and I had to return it today. :( Overnight, as it was charging, the accelerometer just stopped working. And yes, all the "turn auto-rotate on" options were set correctly. It also strangely forgot the settings for my wi-fi adapter which it was linked to all night. Don't know if the two had anything to do with one another. When I went in to recalibrate the motion sensor (by lying the phone down flat, etc.) it gave me an error and said "try again." The only thing I did was leave the phone plugged in all nigh (HowTos)
