Boost your stock rooted ROM with this pitch black theme for the Substratum theme engine. It fully supports Android 7.0 and 7.1/Google Pixel/OxygenOS 4/LineageOS/Samsung S8/OMS + it works without TBO Theme ready gapps!Please read the description below before using the theme.

Root or not root?:Some ROMs requires root, but some don't. We can't list all ROMs here as the list will be too long. You need to look this up yourself.

Marshmallow support dropped?We had to drop support for Android 6.0 due to recent updates in the Substratum theme engine.

NOTICE FOR NEXUS & PIXEL USERS:After updating to the April firmware version you might experience issues applying the theme. In some cases it takes a very long time installing the overlays or applying the overlays have no effect. A common fix is to re-flash the vendor.img in fastboot. If the issue persist try the following: clear Substratum app data and reboot, before trying again.

Important information

Installing / updating theme:The theme is stable to use on ROMs with support for Substratum. The Substratum app on legacy devices is not yet perfectly stable though, and if you run in to problems when installing or updating the theme please try to fix this by clearing Substratum data, followed by a reboot. Don't forget to grant all prompted permissions when opening the Substratum app the first time. If it's still not fixed please contact me by email or Telegram for personal assistance.Any issue related to installation or updating is a Substratum app legacy issue, and not a theme issue, so I would appreciate if you don't tell me about it in the review system but instead reach out to me personally.

Easy fix for app issues:If an app stops working as it should after you update it from the Play Store, please reapply the overlay + reboot

IMPORTANT:Beta versions of apps are NOT expected to work and NOT supported. Please do NOT report issues when using betas; if they work it's good, but if they don't priority is and will be always given to stable versions


You need the substratum theme engine app to apply the theme!

The notification colors are partially set within the frameworks and it's not possible to theme the frameworks in all Android versions. This is why the notifications are white on some ROMs. You can read more about this in the FAQs.
