Open system settings > applications > Next Launcher > clear cache. See if that helps. If not, then it's possibly related to a recently installed update. In that case, I would suggest taking a look through the Play Store reviews to see if anyone else is having similar issues and see if the Developer may have a fix pending.Anyone have any problems adding system widgets to your screen with Next launcher? Everytime I open the system widget option the whole phone freezes and I usually have to restart the phone. This just started happening a few days ago.
