Wifes bone stock Razr, 6 months old and have had nothing but problems with it. Super slow most of the time (not a ram or low memory issue) and now it just randomly looses all service. I can be sitting on my couch and it will go out completely then come back on whenever it feels like it. Is this a known problem with a simple solution or should I just warranty it out? I have already tried a factory reset with no improvement.
