Though, I'll hate to see the theme not being available for users while waiting for it to be available again, so here comes this thread. Please have respect and don't request my other themes. Swift for Samsung users can use this theme too.
Instructions and important information:
APPLY THEME WITH THIS APP (Substratum theme engine app): https://goo.gl/BgncEN
SAMSUNG 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.
ANDROMEDA NOTICE: The 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 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 NOTICE: You need root
APP ISSUES? Reapply the theme for that app and reboot.
WHAT IS NEEDED? for this dark Substratum theme to work? You need the Substratum theme app! And your ROM must support Substratum. You need to look this up yourself. ROOT might be needed for your specific ROM. An addon is needed for Samsung, which is paid, and the Andromeda addon, also paid, is needed for the Andromeda theme engine.
Swift Dark, ROM for all devices (see above for details)
ROM OS Version: 2.3.x Gingerbread
