Substratum Themes

When Android was originally introduced, there were not much customization options apart from installing launchers and changing wallpapers. As time went by, Android evolved. The Android ecosystem grew big in size and so did the amazing Android community.

While some OEMs provide an option to change themes on Android devices out of the box, most do not. That is exactly where Substratum comes in to play. It is a stand-alone application which you can download from the Google Play Store to theme your device.

What is a Substratum Theme?

When CyanogenMod was around, we had CM Theme Engine (based T-Mobile Theme Chooser) which was doing a pretty great job. But then again, to use CM Theme Engine, you had to flash a custom ROM. There was always a void left in the Android theming space. And Substratum did a very good job filling that void. Today, we are bringing you the best substratum themes for Android devices.

Before going ahead to download the Substartum Themes, you should have the latest Substratum app installed on your device:
