Yeah, I have tried a number of different case off/reboot/case on etc combinations. It is actually at a point where I have to keep a small piece of paper in the case blocking the contacts because the phone will freak out and no matter what I do it thinks the case is always closed and the only thing that works is the edge screen. Factory reset the phone, problem persists. Have not thought about wiping cache, is that even an option on a non rooted phone? I would love to go back, but without rooting the phone is that even a possibility? Can't root/run custom firmware since the phone is used for work.
