Good Lock is an incredible official app by Samsung for customizing Samsung devices. It consists of modules which edit and change many things in the UI such as task changer, notification panel, lockscreen, split screen and more. Unfortunately it is only available in a few countries. Even if you install them manually, most of them does not appear in your app drawer. That is where NiceLock comes into play, by acting as a launcher for all of your modules, allows you to access them.
