Mate 20 Pro, Substratum and Andromeda - Black Theme

[2reign0]

Has anyone successfully used Substratum and Andromeda to get an all back UI like on Samsung?

I'm pretty sure Andromeda only works with Android Oreo. The only way to use Substratum on Android Pie is likely by rooting your phone.

You can actually get an all black UI with themes available on Huawei Themes (which is available in the Play Store). There are themes like Deep Black that you can download from XDA that also darken the notification shade but those themes didn't work right for me on all app notifications which is probably why the themes on Huawei Themes and other similar apps usually leave notifications unthemed.
