Welcome to Android Central! Does this persist after a reboot? Try booting into Safe Mode, which disables all 3rd party apps. If the problem goes away in Safe Mode, then something you installed is causing problems. You may have to uninstall apps one by one until the problem goes away. https://support.t-mobile.com/docs/DOC-11474
