Minimum Requirements

The Master Developer apps require devices with Android OS version 6.x (Marshmallow) or later and run on just about every modern Android device. If your device does not support this minimum OS version, you will not be able to use our applications. You can check your current version in your device's settings.

What Does It Cost?

Master Developer applications are 100% free to download and use.

Why do the apps need access to my phone's storage?

In order to use and apply the wallpapers on your phone, they need to be temporarily saved somewhere on your device. Granting storage permission to Master Developer apps simply provides a secure place for those images to be processed and set by your system.

Why am I having trouble updating the apps?

Most of the time, updates happen automatically in the background via the Google Play Store. However, while we work hard to support most device versions, it is not always possible to maintain compatibility with older phones past a certain age.

If our apps no longer support your device, we sincerely apologize and hope that if you upgrade to a newer device in the future, you'll choose to install Master Developer apps again!

The app can't connect to the internet, what do I do?

First, check your network connection, as our apps require an active internet connection to load content. If your connection is fine but the problem persists, our servers might be undergoing temporary maintenance. We appreciate your patience and ask that you please try again later.

Why is the content loading so slowly?

Because we provide high-resolution, premium-quality wallpapers, the file sizes can be quite large. A stable and fast Wi-Fi or mobile data connection is highly recommended for the best experience.

Questions and problems when setting wallpapers

Due to the massive variety of Android brands (Samsung, Xiaomi, Motorola, etc.) and specific launcher configurations used by thousands of our users worldwide, we cannot provide personalized support for configuring individual devices.

If you are having trouble replacing your default wallpaper (e.g., on a newer Galaxy device), we recommend a quick Google search or using the official guide:
