Welcome to Android Central! Does this persist after a reboot? Try booting into Safe Mode, which disables all 3rd party apps. https://support.t-mobile.com/docs/DOC-11124. If the problem persists in Safe Mode, then there might be something wrong with the firmware, and you may have to do a factory reset.
