Android Oreo 8.0 was launched last month. Among many exciting features such as picture in picture mode, auto fill for apps, notification badges and others, Oreo also brings support for Sony’s Overlay Manager Service (OMS), and Substratum themes which support OMS framework can work on Android Oreo without root. This enables us to have custom themes on Android Oreo powered devices without the need of root access.
However, to install Substratum themes without root on stock Android Oreo, you need to install/setup Andromeda add-on on your device first. It’s a lengthy process but is fairly easier to perform. If you haven’t installed rootless Substratum on your Android device yet, check out our step-by-step guide to d so at the link below:

While there are many Substratum themes on the Google Play Store, you have to look for Substratum themes with support for OMS. If a theme’s description on Play Store mentions only “Legacy” or “RRO” support, not OMS, then it won’t work on Oreo with rootless Substratum. And you need to avoid those themes. But to save your time, we have pretty done the job for you. Below are the best 10 Substratum themes which support OMS framework.
