How to Apply Substratum OMS Themes on your Android

Applying the Substratum OMS themes on your Android is pretty easy. For now lets know what Substratum is. Substratum is an theme engine app, downloadable from the Play Store. This app utilizes all of Sony’s Overlay Manager Service (OMS), found on the official AOSP code review. Use Substratum OMS Themes to personalize your android phone. This is similar to Layers in terms of stability and customization as it runs off an upgraded version of the Resource Runtime Overlay system.

The added benefit of running up-to-date Sony code on a customized ROM. Layers as you know was deprecated in favor of Substratum Theme Engine. Thank the Substratum Development Community for developing this amazing theme engine. Learn how to install Substratum OMS themes on your android device.

Substratum is better than layers because:

  • Not needed to soft reboot after applying theme
  • Applying fonts without need of reboot
  • Apply System sounds from a theme, such as lock/unlock/effect_tick sounds, to make your unlock sounds match your theme
  • Does not use the vendor/overlays partition/folder anymore, to limit down possible security vulnerabilities and reflashing vendors constantly
  • Active and consistent development based on upstream Sony code, as well as team code. Relying on the old system meant bringing up legacy code to newer versions of Android even when we know the RRO2 system is being superseded already
