Does anyone know what the small switch is left of the battery, not the soft reset. BTW need ROM's had the phone working for a day and it crashed inside display kicked out. Any assistance would be appreciated.

On device, if you happen to close the flip too hard or subject it to a minor shock, the device will reset or lock up.

The solution to this was inserting a little piece of paper to help keep pressure on the switch at all times.
