Whether you have a Galaxy S21, Galaxy Note 20 or Galaxy Z Fold 3, the best Samsung phones all offer bags of power, superb cameras and features aplenty. But you can make them better still — and all it takes is one app.
The app in question is called Good Lock, and it doesn't get the attention it deserves. That's probably because it's only available for Galaxy devices, and only direct from the Galaxy Store, meaning plenty of people aren't aware of how useful it is.
That's a massive shame, because in my opinion Good Lock should be a day-one install for any Galaxy owner. So what is it? And why is it so special? Allow me to explain.
What is Good Lock?
Good Lock is an app made by Samsung which allows you to completely customize your Galaxy phone or tablet experience, letting you mess about with and change all manners of things. For instance, you can use it for everything from altering the appearance of your task launcher to replacing the icons on your navigation bar.
In short, Good Lock is like having your very own custom ROM for your Galaxy device — except one that doesn't void your warranty.
Good Lock is available to download, for free, from the Galaxy Store and works on most Samsung devices. Download Good Lock here (opens in new tab) and give it a try — and read on to find out what it can do.

Once you've installed and opened the app, you'll notice the names of several plugins. To install a plugin, tap the blue download icon next to it. But before you do that, check out what each of the plugins does, to see which ones you want to try out.
