NiceLock helps you manage Samsung Good Lock modules in unsupported regions
Good Lock is one of the less-talked-about customization apps that is available for many Samsung flagship devices. While the name of the app implies a connection with locks creens, Good Lock is far more than a lock screen replacement. Unfortunately, Good Lock and all of its modules are available in only a few regions like Korea, USA, Singapore, Australia, and Canada, and a simple APK sideload does not work for other regions as the main Good Lock app will likely throw a network error. XDA Senior Member xantrk developed the NiceLock app to overcome this limitation.
NiceLock is an alternative to the Good Lock app for the regions in which it is not available officially. The app acts as a launcher for modules, so you do still need to download the modules from alternative mirrors. But this app lets you launch them without any further hassles, which is a big plus for anyone looking to customize their recent Samsung flagship device.
