Phone was charging in car, then the screen was black with yellow caution triangle. At the top of the screen, a DOS prompt appeared with FACTORY RESET IN RED. The FIRST time I didn't see what it was doing, I panicked and hit the home key and back key to stop it and it erased all my information and it did a factory reset. I was on the phone for 2 hours with VZ Tech who had no idea what happened and had not heard of it occurring. The SECOND time I had someone take a picture of the screen and there were 3 options. Safe mode, normal mode and factory reset. The volume changes the selection and it comes up with the option to factory reset, to confirm your selection you press the HOME key, hit it again on accident. This is very upsetting for this phone is not even a month old and I've talked to people and this shouldn't be happening.
