For the past several days, my phone has been getting an inaccurate time, slowing down over the course of the day. I found that rebooting brought it back, but it continued to drift over the next day, losing about 6 minutes in 24 hours. I just went to the date and time settings, unclicked automatic, then clicked automatic again. It picked up the correct time, indicating that the tower has it right. Any thoughts about how to repair this?
