A day or two ago, my BLU Dash L2 began restarting itself several times a day. Each time it comes back on, the time displayed is an hour later than the actual time. I have to reboot the phone again to fix this error. Then, when I tried to contact someone, the phone froze up for a while and would not unlock. Why is this happening, and how can it be fixed? Could it be part of the wireless update I recently downloaded?
