Hi, on Galaxy S8 will work?
[Samsung Galaxy S9 & S9+ Cross Device Development] Giocarro:
How much disabled HWC affects performance?

Is this ROM as smooth as Pixel (which is VERY smooth) or is it on par with Samsung' One UI ?

I guess I'd unlock my device and take the custom ROM way only if I'm sure to reach a smoother experience; One UI is very nice, but I still see some little stuttering here and there; nothing major, but nonetheless there's room for improvement.
[Samsung Galaxy S9 & S9+ Cross Device Development] EddoWagt:
I'm in the same boat as you, One UI is pretty good and having warranty, untripped Knox and ota available is worth keeping over a non perfect rom imo
[Samsung Galaxy S9 & S9+ Cross Device Development] dimitrispas22:
If you want more battery it's worth it to do all that stuff and if you a fan of stock pixel then it's ??

I will try tomorrow to get my gear S3 after a backup from my current ROM

yeet

just posted an update

19.02.2019

Increased vibration strength

Added walrus's smooth hax (which might be snake oil)

Added vendor version check at boot

Synced kernel sauce with CSB3 (which is now mandatory)

Added fingerprint override in order to pass CTS/safetynet.

Can someone suggest which version magisk because i use 18.1 and it says installed on TWRP screen but when you open /magisk app it says not installed.

Sometimes you need to flash magisk twice. Idk why, don't ask me. But i use the latest 18.1

Hello fellas,

how's camera quality with this ROM? I read OP saying it's comparable to stock, do you share this opinion?

I've never flashed anything on my S9 before and would prefer Pixel Experience a lot to One UI, so I would like to know if camera quality is decent enough to make the switch to AOSP. Also, which camera app are you using?

Thanks a lot, I would really appreciate your replies. :good:

PS I'm really grateful for having Rainbow Dash and all the other devs working on ROMs for our device. Thank you!

I will definitely make a donation should I install this ROM, it's tempting! :o
[Samsung Galaxy S9 & S9+ Cross Device Development] akumaburn:
Seems during the google setup, shortly after updated gboard it goes into a lockscreen loop where it locks the screen and flashes black and lock screen over and over.

This is on the current version with Magisk 18.0 and the latest endurance kernel.

EDIT: I tried flashing the endurance kernel again but this time with _underclock on as I noticed there were signs of overheating before, and now it seems to be working better.

Do not expect Perfect camera from this rom

the quality is like iphone 6s-7 i can not describe it differently due the fact than stock camera is crispier and sharper.... in low light flash doesn't work with the gcam apparently

you can read the FAQ its better than other oreo roms plus super slow motion and some samsung stuff doesnt work

ps the AOD is not bright enough when you outside or in a good light rom

Rainbow_Dash, I think you need to be more clear about this rom being S9(+) only. It being in the S9/S9+ cross development thread and having [S9/S9+] in the title doesn't seem to cut it... I think the first line of the first post needs to be 'S9 AND S9+ ONLY' or something like that xD

I have issues with my s9 plus in this rom every time I playing with the volume scale the volume Geo's down and I here a little sound from the call speaker and I can't hear that way music until I reboot
[Samsung Galaxy S9 & S9+ Cross Device Development] dimitrispas22:
Thanks for your time spending by making this Rom!

i don't have words to say! mostly stable, butter smooth most of the time!, great battery life , the ambient music thats working i was waiting for ages for this since i was OG Pixel XL user

there are a some stuff that doesn't work like noise cancellation , in the messenger photos which are taken doesn't appear and sometimes when watching videos on Facebook sound goes off

speakers are little bit crappy especially when there is a bass i fell the one of them is little bit of or something like that(you can fix it by tuning them with viper4android but still they are not that great

AOD brightness is very low especially when its sunny ...

Battery is very good in my usage compared to stock, the speed is fantastic most of the time it feels more fluid than the stock due the fast animations and launching times which are ?,fingerprint speed is faster in this rom for whatever reason (Rather than stock, or its my imagination??? )bixby button is google assistant which is faster and more responsive that bixby (which is terrible at the moment) and so on!!!

i would like to see call screening works on this Rom, i tried pixify but doesnt work (answering the call just normal rather than in call screening mode) and then the sound freaks out until restart :P

aod auto brightness or to be able to make it little bit brighter , for the camera i cant say a lot i understand that is because of the apks available right now are not that optimized etc

and really i appreciate your work! you are awesome ! (if you can tell me how you learn building custom Roms etc i will be happy because i want to try to build my first custom rom and i dont know which of tuttorials are worth checking! )

and again thanks for your time spent fixing and building all that stuff for our devices ? (sorry for the summary ????)
[Samsung Galaxy S9 & S9+ Cross Device Development] hcan5524:
Hey Dimitri i had a question about the rom i liked everyhing but he battery drain was too crazy it feels like i lose every minute 1 percent even by standby any sugestion to improve the battery life. I dont want back to samsung stock its not so consistent and smooth like pixel ui or IOS.

Thanks in forward
[Samsung Galaxy S9 & S9+ Cross Device Development] dimitrispas22:
check about for apps which are running in the background , learn to have brightness that's comfortable but not too bright, use greenify to force close unwanted apps

don't expect 6hrs of sot time especially if you have the s9 not the plus .... i am getting from 2:30 to 4 hrs max deppents on the usage the brightest and stuff like that....

from 7 the morning until 2 the afternoon i am going from 100 to 50-60% most of the time (in my case i bought the 10000mah battery bank with fast charge (samsung brand)

how old is your device?
[Samsung Galaxy S9 & S9+ Cross Device Development] hcan5524:
Thanks Dimitri for the insides and Tipps.

I boutht it in October it was my first android phone aka Samsung. For the normal user everything fine for the price there are better phones out there.

I tested the rom for 3 day performance unbearable so fast and smooth no lags I liked it so much.

I will try some other Roms 4 hours is a little bit less for me.

Is there any Rom that is like pixel Rom with more battery life ?

Do you know how the pixel 3 XL battery life is because the price of the pixel dropped a lot. I think you meationed that you had a pixel.
[Samsung Galaxy S9 & S9+ Cross Device Development] OcainD:
How SOT on this rom?

what kernel should i install with this rom? thanks for the hard work m8
[Samsung Galaxy S9 & S9+ Cross Device Development] LavaSnake54:
Always use endurance kernel
[Samsung Galaxy S9 & S9+ Cross Device Development] dimitrispas22:
sot 3:30 to 4 (little bit better than stock ) if you own a plus model expect better sot
[Samsung Galaxy S9 & S9+ Cross Device Development] OcainD:
I just got one question, i am kinda noob and i hadnt installed custom roms since i left my galaxy s4, 4 years ago.

what does it means that i should be in CSB3 based vendor? should i flash the CSB3 file that you left in the thread after installing this rom? thanks
[Samsung Galaxy S9 & S9+ Cross Device Development] saoocheen:
hi i really love this rom because it's simple and fast, thanks for sharing it

everything like aod and fingerprint works but for some reason youtube and spotify won't work,

i'm using csb3 fw and vendor and followed all the steps, anyone else having this issue and fixed it please help
[Samsung Galaxy S9 & S9+ Cross Device Development] LavaSnake54:
Do you have any kind of adblocking?
[Samsung Galaxy S9 & S9+ Cross Device Development] OcainD:
I installed the rom yesterday and everything is working fine, battery is almost as stock, and is way smoother.

The only thing that doesnt work good is the camera, in the first hours it worked right but then it says that "camera keeps failing" and it doesnt start

Btw camera in third pary apps like WhatsApp or instagram works very well. But not in the stock app or google camera

How can i fix this? I really like the rom but this is my only problem

Should i install endurance kernel or flash something? Help
[Samsung Galaxy S9 & S9+ Cross Device Development] fayeharuna:
I have the same issues
[Samsung Galaxy S9 & S9+ Cross Device Development] dimitrispas22:
install magisk and install audio compatibility patch
[Samsung Galaxy S9 & S9+ Cross Device Development] MetalPhoenix45:
[/COLOR]

Hey I was wondering the same thing. But I figured it out, download the CSB3 vendor image from OP then download fw from

https://mega.nz/#F!wFFQUYbI!GZvNOBSn1wVn8U9mQDzBiw!kIMEBKoZ

Then flash the zip and for the vendor image you have to go to where you stored it on twrp then press Install Image on the bottom right and select the vendor.img then Select Vendor Image.

Daily use

Is this ROM now good enough for daily use? ?

Does Google pay, pokemon go, banking apps etc work with or without(preferably) Magisk?
[Samsung Galaxy S9 & S9+ Cross Device Development] LavaSnake54:
I am sure for the most part it's perfectly stable for daily use. There are only a few drawbacks like the known bugs and (rom related) there are no customisations in this rom. Also, you will lose some useful samsung features like dolby atmos and the camera app. So yeah if you're okay with all of that this will suite you perfectly.

Talking about SafteyNet it passes even without magisk now. So you can use any if those apps you listed (not sure about google pay though.)
[Samsung Galaxy S9 & S9+ Cross Device Development] jafro77:
It would be great with bundled LED control and working Gcam for it to be a daily driver, otherwise very good ROM.

Yes it did for me, the videos were not playing in YouTube because of the audio issue. Try it, see if you're having any luck.
[Samsung Galaxy S9 & S9+ Cross Device Development] Aquajd:
Hi all, I am having endless trouble with this rom on my Samsung Galaxy s9+ that seems to be worsening the longer the rom is installed. I have installed from soldier - but reverted to stock after an initial wipe so it shouldnt have made a difference - whilst a list of grievances here it is an amazing ROM and hopefully further development will see these bugs resolved. They are as follows:

1. YouTube and videos do not play unless routinely deleting the app, clearing the device cache and reinstalling the app. And then for a limited time

2 TWRP app can only be found by searching for it in the Google search bar - it does not appear in the app list, recently used list or even the settings>apps list.

3. Developer options have to be searched in the settings app - it is not visible in the menu list at all.

4 about this phone reveals only basic information with no options - software versions, security patches etc are all missing. I have my SIM slot details and thats it. software versions etc cannot even be accessed with the search function.

5. Data refuses to work on both wifi and data intermittently and frustratingly - clearing device davlik cache fails to produce anything reliable - the device data starts working when its good and ready. In the quick menu - mobile data turns off and on randomly and is often greyed out.

6. Logcat appears to be a feed with audio issues listed only. Can provide a copy of the feed if required

7. Using third party apps I have accessed the OS version listed as BIG CHUNGUS listed in the image below. Based on urban dictionary definitions of this term it seems a point to bring to your attention.

[IMG="BIG CHUNGUS operating system"]https://ibb.co/HHtz4MH[/IMG]

"https://ibb.co/HHtz4MH"

8. Brightness cant always be adjusted remaining at the highest levels - irrespective of whether adaptive brightness is on or off- this resolves by restarting into recovery and clearing the device cache and restarting. It will then suddenly blare back to the full brightness without a yet known trigger.

9. SD card is never detected and annoying notification remains fixed.

10. Notifications for WhatsApp and messages arrive but cannot be accessed from the notification and are missing from the app itself. Tests to this regard in whatsapp have found that even when messages arrive they will subsequently disappear.

11. Images sent on any app fail to send or be received - images taken by the camera often disappear completely.

12. Navigation started out as smooth and efficient- now lags, freezes and apps systematically no longer work (either fail to launch or fail to connect to data) this is deteriorating the longer I use it

13. Battery efficiency is poor and device overheats

Shame as this was my favourite rom and a clear winner when installed. Happy to provide logcat logs or any further information to assist development.

[Samsung Galaxy S9 & S9+ Cross Device Development] Anchor87:
Yes, first flash the vendor image and then flash the ROM.
[Samsung Galaxy S9 & S9+ Cross Device Development] Vmb265:
Well....

1. Use audio compatibility module for magisk. Seems to fix the problem always

2. Idk

3. It's now in the settings> system menu. Changed since pie

4. That's not true. I'm writing this on the same rom and I can very well find those stuff

5. Data on both wifi and lte is only supported by Samsung's software. It's not a aosp thing

6. Same magisk module sold fix audio problems

7. That's a [MENTION=6185853]Rainbow_Dash[/MENTION] thing. And the os version isn't big chungus.

8. That's too not a bug for anyone else. Make sure your on the right firmware and vendor

9. Newer endurance kernels and the ROM itself have fixed the issue. I think your on some older versions

10. Idk. Maybe wind down from digital well-being or DND service is on

11. Again. That's something in your side

12. HWC fix plox [MENTION=6185853]Rainbow_Dash[/MENTION]

13. I would have again [MENTION=6758949]Ed A[/MENTION]lex but he'll go mad at me ^^

Just wait patiently. Devs will fix the bugs sooner or later

Can I I stall this if I'm on CSD2 firmware.
[Samsung Galaxy S9 & S9+ Cross Device Development] Cecillatour:
Many thanks to the dev for this ROM!I tested the dev’s LOS16, his semiGSI Pixel Experience and phhusson’s GSI. In my experience this is currently the best AOSP ROM for S9+ although phhussons’s GSI has better battery life (which does not mean that PE is not good).

I am running in with the Endurance kernel and didn’t experience any issues the other users were mentioning. It was my daily driver for a couple of weeks.

There are few quirks of course but nothing substantial. For example, general screen casting doesn’t work but it works within apps. Gcam shoots overexposed photos but I suspect this is a kernel and not ROM issue. Snapcam, which comes with the ROM, as well as OpenCamera work very well.

I would therefore like to encourage the dev to keep maintaining this ROM. For me the ROM is snappy enough even without HWC. I compared it with my friend’s S9+ running StockROM and PE was faster.

I would be grateful even if the dev would just keep updating the security patches. This is currently the only issue that could eventually prompt me to change the ROM.
