NEWS! Apparently Play Store 8.3.72 will only be themed if you use English as device language. We don't know why but are investigating it.


Instructions and important information:

ATTENTION! If an app is crashing you need to reinstall the overlay for that app and reboot. Why? An overlay from the theme is applied on top of the app. When you update an app from Play Store the overlay won't be on top anymore. When you reinstall the overlay you will make sure it gets applied on top again.

APPLY THEME WITH THIS APP (Substratum theme engine app): https://goo.gl/BgncEN

SAMSUNG THEME NOTICE: The Samsung theme add-on (paid) is required for Samsung users. You'll be noticed about it when you launch the Substratum app on your Samsung device. You MUST remove all overlays before doing an OTA firmware upgrade or you might be forced to hard reset your device.

ANDROMEDA THEME NOTICE: The black Andromeda theme needs a separate paid addon to work. You'll be noticed about it when you launch the Substratum app on your Andromeda theme supported device. The Andromeda theme engine makes it possible to apply the theme on a rootless Oreo device.

ANDROID 8 / OREO THEME NOTICE You must reboot your device after installing or updating overlays on Android Oreo! This is required for the system to update the apps. Also don’t apply all overlays at once as it might cause issues. Apply 5 at a time.

ONEPLUS THEME NOTICE: You need root for the OnePlus theme ( OxygenOS theme ) to work.
