Actually, Substratum theme engine does work on this ROM. I Flashed it, then installed Substratum, then the dark theme I use and it's working just perfectly fine.
Nice maybe I'll try. I only assumed without trying.
You still need the Andromeda add on for Samsung right?
Kinda funny to pay 4$ (Andromeda plus theme)just to apply black theme but maybe I will.

The U model S8s are real temperamental on CSCs. I have not tried this but I did notice a comment for not working on verizon, And I run Xfinity mobile which runs on verizons towers.But has a setup method of its own....As it activates partially on my home router.
I have noticed in past that a lot of these issues can be solved by flashing your respective carriers CSCs

Quick update
Big plus for standby battery life standby!
Was draining usually about 15% during night with radio on and about 4% flight mode
Tonight I drained 1% with WiFi and cell on!! ?

Camera send a little blurrier compared to stock too my eye
Haven't really played with it that much yet though and installed modded versions
Also lack of sleep card same is a bit annoying

For some reason smart switch would not restore my SMS on this ROM and obviously Samsung cloud is not on here

Will try later if I get a chance to play with getting some Sammy all back like camera

Yeah, but it looks so good! I purchased the theme almost 2 years ago, to use with my Nexus 6P. Luckily, it's a popular theme and still supported with weekly, or more, updates.

I agree it is very nice... What theme is it? Haven't used substratum for years..
I hate all the white they use now... Always choose black theme.

Yeah I bought them.... Got the black one tho.
You really have to verify on a PC to install theme every time you restart??

Yeah.....It's a pain in the butt!

You have to start the desktop verion of Andromeda, which automatically opens Substratum on your phone. If it doesn't, or you close out, you can open it manually.

Then you apply your theme (Build and Enable, I believe it what it's called). Then you have to restart your phone and start the process over again. This time, you have to go in, check-mark them, and "Enable" them. Then, it's a good idea to restart one more time.

It sounds tedious, but I can literally do this in less than 3 or 4 minutes. Building the themes takes longer than the restarting and starting Andromeda on your PC. It's also quicker than it was in Nougat, where you had to "Install" each individual overlay, then restart your phone. The Oreo version also seems a little more stable, with less errors.

But yes, you have to connect your phone to a PC (or Mac) to get the process to work.

If you decide you don't want an app themed, because you don't like it or it's crashing, you just (start the process again) and disable the overlay, no need to restart....But I do, for good measure.

This is the best ROMs I've used for battery life. Simple phenomenal. Has anyone here gotten bxactions to work, though?

I tried bxactions but no option to remap bixby button..
Use all in one gestures as mentioned in OP
Give permissions and add the button that you want to be map and choose the action you want to change to.
I changed to no action
Good luck.

Thanks man, it's too bad bxactions isn't working atm. I'm settling with AIO Gestures, and it works, but not as good as BX. Oh well, you win some you lose some!

Same thing happens if I open play store and when I open Google app it says Stopped working. I tried all the given steps removing cache updating apps manually. But not able to succeed. Please, can anyone help me with this?

I'll just try not to reboot unless I'm home....lol
That white background is no good. Glad some kind of themes work on this rom at least.
This rom is standby drain king!
About 50% less screen off drain than stock crb9 in my testing

Main thing to remember is that you don't lose overlays when you reboot so the PC is only needed if you want to make a change

    I was running into weird problems with this new Odin. I have a Mac running windows 10. I tried flashing this and did every step by the instructions. It did exactly everything except wouldn't start. Then it but would flash some screen and reboot to upload mode generic one. I had to close out Odin every time I flashed something because sometimes I would get an error in Odin. The first time I flashed and the few after with no luck it didn't give an error and flashed the second to last time it errored. So I reflashed, closed out everytime time and it worked. But was having trouble texting. So I flashed my carrier CSC with the user data file. The user data completely wipes the phone so no data from anything is deep in there or anywhere. You need your home CSC. My WiFi calling and most the problems listed don't even exist on mine. I am on t mobile on a branded sprint phone sim unlocked. Sprint s8 are the worst s8's. Sprint has their own bullshit. Verizon is usually the easiest because they are the ones most other carriers base their off of. Example is every rooted method uses the Verizon build.

    thanks for the insight! I found a different way now though...

    I just went through the setup process with that stupid popup every three seconds and eventually used this method to get rid of the service:
    https://www.xda-developers.com/uninstall-carrier-oem-bloatware-without-root-access/

    it works very well now for me :)

    Quite unclear, so this rom does not trip knox, it's just that knox is unavailable? So if I flash the stock rom it will work again?

    This doesn't trip Knox flag but all Knox and a LOT of Sammy stuff is gone so you can't use Knox based stuff like BKDisabler. When you flash stock again it's all normal.
