This is the third update of the update after the original release back in 2016 when it supported Marshmallow devices. It was later updated in 2018 to support Oreo, and finally, the 2019 update brings the long-awaited support for One UI. Follow the tutorial below to learn to install Good Lock and all of its add-ons on your Samsung phone.

Good Lock is a customization app for Samsung phones. It is a software application based on add-ons. It has no functionality by itself, but it is the main program that controls the additional add-ons or plugins, which are the ones that actually customize the user interface of the phone. This app is very popular, especially since Samsung is not the greatest company when it comes to software design. Before you download the app, let’s see what kind of add-ons you can install, and what is their functionality.
