About this app

This supports Android Oreo without root, using Andromeda! If you have root, everything should work out of the box except on Samsung!

Take over control of the finest aspects of the system UI and personalise your Android experience without limits with the official Substratum theme engine, free to use and powered by the constantly growing, community-driven collection of beautiful overlays.

Google is preventing stock OMS users from utilising custom overlays. To help us bring back rootless theming support to Android, please star the following issue in Google’s Issue Tracker:

Theme engine support:
• Stock Oreo (OMS): Compatible with rooted and unrooted devices, in the case of the latter the Andromeda plugin is needed for Substratum to function correctly:

Detailed guide:

Having external, third party theme clients installed may cause issues with Substratum, including unforeseen bootloops, crashes, and more. Customer support will refuse to provide assistance to users running such applications, including Swift Installer.

So it has always been one of my favorite apps - even if flawed and difficult at times, but right now all of a sudden, im getting a notification that the app has a trojan dropper in it. I'm going to assume & hope it's a false positive -but ESET is usually the only antivirus that doesnt do l tend to do that. Then again, it happened out of nowhere.... So idk. What's up with that?

Since the latest update, my phone has been doing some wonky stuff. A few apps stopped working all together. First, let me be clear. The only thing I use this app for is to skin the navbar at the bottom on Android 7.1.1 Shamu. No themed apps, etc. Yet, right after the 1007 update, Weather Underground wouldn't connect and pull the weather. It would simply say "check back later." And Soundcloud wouldn't play any tracks. It gave off an error as well. I'm also having issues uninstalling and reinstalling apps, downloading them from the Play Store and other various weird glitches. Substratum is the only thing that has changed on my system. Still, I love this app. I'm going to try some things to see if they fix the issue.

Verification failed. That's all it says now. I've been using this app and enjoying the themes for months now. I tried force stopping and clearing the cache. It didn't work. I can't uninstall Substratum and Andromeda because l have layers installed. I know if I uninstall those apps, my phone will become extremely slow and be completely unusable. I know this because I made that mistake when I first got this app. You need to implement a way that can uninstall the layers even if verification has failed. Now I need to figure out a way to get this working again at the risk of my device.

Uninstall and reinstall both Substratum and Andromeda, then wipe Substratum cache and data in your device settings, apps, Substratum, storage. And yes you can uninstall and reinstall them, 1000's of users have done exactly that with no problem. If you still need assistance, read the app description - Char
