Pixel Experience ROM for the Galaxy S9+ and the Galaxy S9

What is this?
Pixel Experience is an AOSP based ROM, with Google apps included and all Pixel goodies (launcher, wallpapers, icons, fonts, bootanimation)
Our mission is to offer the maximum possible stability and security, along with essential features for the proper functioning of the device
Based on Android 9.0
This it not a GSI. It is built on actual device trees

What's working/not working?

First up:
-HWC is disabled
-The signalbar always shows 0, altho calling and data have no issue and should work as intended.

Obviously Samsung's own features such as Samsung Pay, KNOX, Theme Center, Game Launcher, etc. won't be ported to LineageOS Pixel Experience. We may have our own implementation to similar functions, though.
Iris sensor does not work because AOSP upstream does not support that yet.
IMS services (VoLTE, VoWiFi, etc). Samsung has their own proprietary implementation. It is not really possible to easily port that to LineageOS PixelExperience.

Make sure TWRP has been installed and functional.
Make sure you are on the CSB3 based vendor and fw
Download the latest build linked below
Reboot to recovery
Wipe system, data and cache from the wipe menu
Flash the rom zip(and gapps). DONT flash gapps. they are already included in the rom.
(optionally) flash magisk
Reboot and enjoy :victory:

Providing feedback:
You are more than welcome to provide any kind of feedback here.
(limited only to feature requests; it's called "pixel experience" for a reason and it should stay that way)
You can also msg me anytime on telegram @ Rainbow_Alex_Dash

Telegram group?


Increased vibration strength
Fixed sdcard issues some people were having
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.


Q: Videos aren't playing on youtube
A: Make sure you don't have any kind of adblock installed

Q: I'm on a dualsim variant and (a) sim isn't detected.
A: Try reinserting your sim and rebooting. This wierdly nuff only happens on some* dualsim variants and no one has sent me a logcat yet.

Q: My mobile data (3G/4G) is not working/only 3g shows
A: Go into mobile network settings and select/create an apn, also select 4G as the preferred network type.

Q: How does this compare to GSIS?
A: Much better all around. Faster,smoother etc. I don't think there's any reasons to use pie gsis anymore.

Q: How good is the camera?
A: Actually,(by my standards), pretty good. Almost comparable to stock. Ofc the aosp cam doesn't have the fancy filtering, features and stuff but by far not bad. Alot better than 8.1 roms anyway.

Q: Safetynet doesn't pass?
A: Yeah, i guess that's a thing. Go into magisk and download some module called props hide or something. Don't forget to run it from terminal. It should work from there

Q: The rom isn't booting/camera doesn't work
A: Flash/make sure you have the CSB3 vendor and fw, and try again. This has been tested. It's prolly something on ur end.

Q: The rom is in a bootloop/google apps keep crashing
A: You did read the instructions and NOT flash any gapps riighhttt?? smh, wipe /system,/data and /cache and start over

Q: I have another bug; How can i tell it to you while slightly increasing my changes of it ever getting fixed.
A: You can tell me what's going on either here or on telegram WITH A LOGCAT attached(required);if rom isn't booting at all attach /proc/last_kmsg.

Q: I don't know what/how to logcat. Is it really necessary?
A: Logcat or gtfo

Q: How can i support you?
A: Awwww thanks; On most of my posts on the left side there's a "donate to me" paypal button;. Send the seal some fish. Seriously. The seal realllyyyyy loves fish. You can do that,donations are more than welcome, or if you don't have any $ to spare you can also post here about how awesome i am (this surprisingly helps very much)

Jesec for the initial trees
The pixel experience team for creating the rom we so do enjoy

Thanks for the Rom! Working good :)

Some things I noticed:

-SD card isn't working. Always says tap to fix
-some animations could be smoother but it's because of the HWC

Great first impression so far.

Thanks again!

Just a quick update:
Mah boi @Eamo5 is cooking up endurance kernel for this, and he claims w it it's much smoother. Idk, i guess we'll wait and see.

Also i've build a couple other roms and will be opening threads shortly
Beta release of Endurance is available in the telegram group. An XDA release will be coming shortly

what about the battery on daily usage?
i am wondering if its better than the stock which i am getting only 2 to 2:40 screen on time
(and the last question does ambient music work or not?)
(i still did not root or tripped the knox but i am coming from th OG Pixel and i missed stock android and i dont know if it worth it)

You prolly have the dualsim variant. Can you try removing the simcard tray and rebooting
Every reboot yes dualsim. I have to removing sim tray and no signal is shown never and mobile data not working at all.

Please can you fix that. I love it because EdXposed work with it.

Some bug report:
1. Gboard sound and vibration disappear every time after restart or vibration mode on/off.
2. Settings menu randomly change its theme form white to black. Killing in recents helps.
3. All system vibrations are f.... You know that :)

Everything else is pretty smooth though :)
