Samsung's Good Lock is a software suite that lets you unlock the full customization potential of your Galaxy phone. Basically, Good Lock contains a series of modules designed to tweak every facet of the user interface, including the lock screen, notification panel, overview menu, and much more. Need a vertically scrolling app drawer? You can set that up with Good Lock.
Samsung overhauled Good Lock two years ago, and the service has continued to pick up new features. The suite now has 20 modules in total, and you can choose what modules to install based on your needs and willingness to tinker with One UI. So let's get started with Good Lock, and see the extensive customisation that is possible on your Galaxy phone.
I remember in the past, even on Google phones, having to root the phone to obtain this type of access to customisations. So it is quite welcome that an OEM provides out of a "secondary box" themselves. Essentially you need to install the Good Lock app from the Galaxy Store, and can then choose which modules to install and activate.
For some reason (and no-one seems to know why) the Good Lock app is not available (or active) in every region. So if that is the case for you, you can alternatively install the Fine Lock app from the Google Play Store. It is a bit more indirect with regard to the modules, but it firstly does take you directly to the correct download page on APKMirror, and secondly it does provide the same integrated experience as the Good Lock app itself.
