Relock and flash stock if you haven't already. Take your phone in, describe the problems you've had calmly and concisely, emphasize the repetition of these problems and the inconvenience it has caused you to come in over and over. Tell them you've already hard reset the phone and confirmed it could not be software issues (They'll probably still look at it but whatever). Tell them you want out of this device and into another, mention seeing something about TP's being replaces with other models. They will look it up in the portal and find a service announcement allowing them to replace it with a list of phones. Consider your choices, order a TP2, rejoice that you only have to have your TP for 3-5 days and then go pick up your new baby. Lather, rinse, repeat.

EDIT: By relock and flash stock, I meant flash stock and relock. Just for clarification.
