The Finesse is very buggy. I had this problem and tried everything including a reset and software flash. Ultimately, it started working again on its own one day. The problem has recently begun again and has now been slow/frozen for a few weeks. Several other people that I know that have the phone have had the same issue. I cannot believe Samsung would turn out such a piece of garbage. I will ship it back for warranty service, sell it, and avoid Samsung and Metopcs going forward.
