Unfortunately, Good Lock only works in specific areas of the world, namely the United States, South Korea, Singapore, Australia, the U.K., and Canada. If you live outside of those areas, Samsung Good Lock is unavailable to you.
However, there is now a third-party, unofficial workaround to this problem: an app called Nice Lock which works all around the globe and supports the same official modules as Good Lock.
To use Nice Lock, you simply download the app from the Google Play Store and then search online for the Good Lock modules you’d like to install. You can search for modules from sources like APKMirror, SamMobile, or the XDA forum thread where the developer announced the app.
To be clear, when you download the Nice Lock app from the Play Store there won’t be any modules included. You’ll need to download them separately.
As of now, Nice Lock supports several languages — including English, Italian, Spanish, and Portuguese — and the developer promises to update the app each time a new module from Samsung drops.
Nice Lock comes in two versions: a free app with ads or a paid app with no ads. The paid app costs $4.00 at the moment. Check out each app using the buttons below!
