Help is here! Let's ensure your device is back working as expected! Are you using any 3rd party messaging or keyboard applications? If so, first try resetting the application http://vz.to/12kxQl1. If that doesn't work, please uninstall the application http://vz.to/16zNhGg and retest.
You can also test the device to see if an application is the culprit by testing it while powered up in Safe Mode http://vz.to/11Z3Lmz. This will help determine if the problem is application related. If it persists while in Safe Mode, I recommend Hard Resetting the device http://vz.to/12q1uBa. Just ensure you back up your data prior to resetting. Keep me posted with the results of your testing. Thanks!
