[Substratum] Sai's Oreo Theme

You will be required to install the Substratum Theme Engine and have root access OR the Andromeda add-on, if you want to apply this theme:

https://play.google.com/store/apps/details?id=projekt.substratum

For rootless theming with Substratum, you will have to purchase the Andromeda add-on pack:

https://play.google.com/store/apps/details?id=projekt.andromeda

A bare-bones Black theme for Android Oreo that focuses on nothing more than theming the system. The theme is best used with STOCK or AOSP based ROMs. It will definitely work on any Android Oreo system, but it will not theme it as perfectly as on vanilla Oreo. For other apps, I recommend using my Fresh Theme (https://play.google.com/store/apps/details?id=baka.sai.theme) which is also available for free!

If you see un-themed/partially themed notifications even after installing the theme, please manually reboot the device (recommended) OR clear all your notifications.

System components themed as of now:
• Android system (also themes the Settings app)
• Files (com.android.documentsui)
• Package installer (com.google.android.packageinstaller)
• Settings (com.android.settings)
• System UI (com.android.systemui)
• maybe more...

Known Issues (as of 2018/01/10):
• [No fixes possible for now] WhatsApp, Uber black/dark notification header texts when using dark notification options

I found out about this theme from the XDA Developer Forums' tutorial on how to install a Dark Theme on Android Oreo without Root. The one theme for Substratum out of a handful of both paid and free themes that I could get to work for Oreo 8.1 with the Nova Launcher app installed. The dark transparent theme looks beautiful on my phone. Highly recommended, especially if you are not using the Stock Launcher.

only 1 issue is that , mobile network section in network & internet settings is not themed properly , the text on that page is black that means black text on black bg which makes it impossible to see whats written over there......

Installed on pixel 3 XL and got immediate boot loop! And a warning about my data being encrypted in TWRP? I've used quite a few other themes and haven't had this issue

Doesn't work on my Asus Zenfone Max pro M1. Tried rebooting clearing cache data everything but to no use.

Works perfect, Wish it had a Deeper/normal Green color option, kyoshi is bleached green, and Uranium is a weird neon-esk shade of green.

Tas. R. May 25, 2018     

I love the theme overall. But in some apps the icon label dissapears. I have moto z play. So please try to fix this problem

Kha. Apr 8, 2018     

can't seem to get notifications to get themed properly (white on white text) even after reboot and clearing EDIT: apparently i didn't have everything set to transparent. problem solved!

Cam. B. Apr 20, 2018     

Great theme overall. One small problem for me personally - I can't read the titles of emails that come into gmail. The font color of the text makes it completely unreadable on either the black or the dark backgrounds which are what I'm wanting to use. Any ideas to try?

Noa. M. Mar 25, 2018     

Open source and enginuity win again. Thank you Sai, your theme bested many of the paid dark themes. Keep up the great work!

Pra. May 24, 2018     

Really great theme but there's a problem with the notifications i get. I selwcted the dark notification option and all i recieve is a black bar whenever i get a notification and i cant really see the text inside. Please fix!
