community-developed theming, catered for the community, by the community.

What is Substratum?


Substratum is an application, downloadable from the Play Store, that utilizes all of Sony's Overlay Manager Service (OMS), found on the official AOSP code review. This is similar to Layers in terms of stability and customization as it runs off an upgraded version of the Resource Runtime Overlay system, with the added benefit of running up-to-date Sony code on a customized ROM.

Features of Substratum


Simple & Lightweight

Never again will you need to worry about having themes being mutated in the background without you knowing!

Enthusiast Friendly

Always wanted to have your favorite theme in red? Background in black? As long as the themer adds support for it, anything is definitely possible!

Rootless at Heart

Afraid of the scary monsters we call Android malware? We are now running rootless as a base, enriching the user experience with a trusted, sandboxed experience!

Runtime Theming

Unlike our previous implementation of Layers, our theming system now swaps overlays on-the-fly! No longer will you have to reboot to switch a color, or a theme. Everything happens immediately!

Runs off AOSP-approved code

Want to enjoy the best of AOSP stock? We do too. We did not want a theming system that would bog down over time, so Substratum will only run on user-demand, never in the background without knowing!

Backed by a wonderful community

Our contributors, themers and developers are always happy to help with issues regarding bugs, theming or even understanding code!
