New to One UI? Discover almost endless potential to make it yours.
Reading time: 3 minutes
New Galaxy phone users who have just switched from iOS to One UI for the first time may have noticed some surface-level similarities between the two platforms. But one thing Samsung's One UI excels at is customization, and today, we'll tell you how to maximize that potential.
You may have seen a glimpse of how flexible One UI can be when we explored navigation methods and the app drawer not long ago. Since then, you may have even customized your Galaxy phone in a way that feels familiar and more iOS-like. You want more? In that case, you need to know about One UI's secret weapon: Good Lock.
One UI is the only Android skin that can be extensively customized through Good Lock. The latter is a Samsung app suite that supports a variety of plugins, also known as modules, each expanding the range of customization options for different facets of One UI.
Good Lock plugins can be downloaded from the Good Lock app's main screen and include:
With Good Lock installed on your Galaxy phone, you can go beyond the default One UI customization options and truly personalize your experience in ways that you can't do with any other phones powered by Android, iOS, or anything in between.
For an even closer look at what Good Lock can do, you should check out our YouTube channel, where we have a series dedicated to the best and most useful Good Lock modules. Our Good Lock video playlist is embedded below.
If you want to give Good Lock a try, you can download the app from the Galaxy Store or Google Play. Once installed, you can launch the app and choose which modules you want to use on your Samsung device.
