How To Use Good Lock On Your Samsung Device

Good Lock

The main benefit of Android is its customization and the millions of apps to do it. While Google’s stock Android experience is considered the epitome of perfect software, manufacturers like Samsung and Huawei have their own skin atop Android which is not in a good taste for many people. Well, that has changed. Samsung has improved its lackluster TouchWiz UI and replaced it with the more user-friendly (and size friendly) One UI. Although the software is near-perfect, Samsung enables its users to further customize their Galaxy devices with an app called Good Lock, which lets you change different aspects of your phone like the status bar, lock screen, etc.

The app is divided into two sections with 14 different apps to customize your Galaxy device. Once you download Good Lock, you can choose which app to download. Keep in mind, the app supports devices with Android 9 Pie and above. If your Samsung phone is on Android 9, dive into this tutorial.

Download the Good Lock app from the Galaxy Store or sideload the apk file from this link.
