GO Locker is one of the most powerful tools for customizing your Android device. It allows you to completely alter the look of your device by changing its background and theme. It also offers an effective lock screen that works on most devices and versions of the Android OS.

Please don't stop the music

To use GO Locker you will first need to have the GO Launcher EX installed - although you won't actually need to be using the launcher’s other features.

Opening Go Locker you are presented with a default theme, but this is heavily customizable. You can set your theme’s look and backgrounds, as well as deciding what information, alerts, and links can be accessed from your lock screen. It also features a music player that links to Spotify, Google Music, and other music apps without the need to unlock your phone.

Want it your way?

To help you with the personalization of your phone, GO Locker enables you to download dozens of different, free and paid themes to match your mood. Each has its own custom background, method of unlocking, and advanced options - letting you make your phone look however you want.

Outside of its themes and appearance, GO Locker's general options are quite limited. You can set the default background for any screen, choose between numeric or pattern unlock (and set the code), and also select the sound various actions make. The usefulness of all this will be dependent your current device.

Perfect for older devices

If your default Android OS options are not meeting your needs, then the GO Locker is the perfect app for you. However, many of its features now come as standard on newer devices.
