So even without the phone case, my phone is still turning on and off by itself, constantly throught out the day. Also, it has made a weird noise when it cut off while my music was playing. it sounded like a horn. At home, i have to always connect to my wifi, even though my settings are connect automatically. Then, when I go to work i put my phone in airplane mode to save battery without turning it off, but then the time changes on its own, and the date changes to a few days back. I liked the droid when i first bought it, but i will be getting a different phone if this keeps up!
