I have a problem with my phone eating up my battery. I took it to att and they did a factory reset on my phone. I just with I only had the battery problem now. Since they did the reset, I have contacts in my phone that I haven't seen in 6 years. And some on them, I don't know at all. I delete them and they come right back. All of my contacts are in all different places in the list. They are no longer listed by last names first. this, I can live with. It is all of the people in my contact list that I have a problem with.
