Finally got around to installing on my S9+. Everything I've tried so far is working great. I'm on BRJ3 and was too lazy/didn't want to downgrade so I flashed the Endurance Kernel over it and haven't had any issues (yet).

Thanks very much for all your work!!!!!

Don't know if possible but can you get HDR working with YouTube and what not
Great rom though

Install Youtube Vanced, it can force HDR on devices ( in this case a rom ) which don't support it.

EDIT
And HDR is working fine in YouTube, are you sure you opened a HDR10 video?

    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

    Semi-GSI? what's that?
    a semi-gsi (at least by my own definition) is a gsi built from source, with heavy patches intended for a specific device that wouldn't make the gsi necessarily as universal as a gsi should be. so in terms: don't flash this on other devices.

    How does this differ from any other gsis out there/what are the features?
    Well this includes a number of fixes including:
    Dual speakers are working.
    Ui lag is no more (at least 99.99%).
    Aod is working/enabled.
    Auto brightness is kinda working.
    MTP is working
    Other performance fixes and improvments.

    What's working/not working?

    First up:
    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.

    2ndly the semi-gsi has a few quirks of it's own. Nothing major or worth noting but you should check the "anything else i should know?" part in the FAQ. hence why HWC is broken


    Instructions:
    Make sure TWRP has been installed and functional.
    Download the latest build image and kernel linked below
    Reboot to recovery
    Wipe system, data and cache from the wipe menu
    Select flash image in twrp, lower right side on the install menu
    Flash the rom image as system (and gapps). DONT flash gapps. they are already included in the rom.
    Flash the kernel image corresponding to your model as boot
    Reboot and enjoy :victory:

    Downloads:
    Galaxy S9/S9+ Exynos semi-gsi image link: (G965F/FD/S/N): V3

    Kernel image link(important to use this. read more in FAQ):
    S9 Exynos: V3

    S9+ Exynos: V3

    Note 9 Exynos: V2.3

    Telegram group?
    I usually like to hang around here . It isn't mine but hey.

    Video Review:
    YOUTUBE

    Troubleshooting/FAQ:


    Q:Can i use any other kernels with this gsi?
    A:Nah, not really. I built this kernel specifically to work with this gsi and it includes a few major fixes (for example mtp won't work,major ui lag, no dual speakers etc if you switch to another kernel. But again. If you want to use other kernels, they should* boot. Endurance kernel even has my dual speaker patch and i confirm as working. But again expect bugs.

    Q: Is there anything else i should know?
    A: Ehhhhhhh, not really. I mean there are some stuff i'm really not proud of,for example to "fix" the ui lag i had to set the minimum gpu frequency to 455; this shouldn't create any issues(perhaps some battery drainage when screen is on) but afaik it doesn't impact sleep or anything else.

    Q: My mobile data (3G/4G) is not working
    A: Go into network settings and select/create an apn

    Q:Would this be preferred over a device specific rom?
    A: Overall nah. The reason i didn't set on building device specific los16.....well actually i did and failed. But this is a pretty good placeholder until someone more skilled than me takes over and creates pie device trees.

    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 BRI4 vendor, the linked kernel and try again.

    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; You can use 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)



    Credits:
    The lineageos team; device maintainers who did a wonderful job at creating device trees
    The pixel experience team for creating the rom we so do enjoy
    Many good people from the telegram group (linked above) that helped me create this project and spamming for etas
    And most importantly thanx to iqblal_sareem best creationner ev3r.

    Oke, so I did say that I wanted to ditch this ROM
    Buuuttttt apparently Max from highonandroid (whom I'm a very big fan of) made a video review of the ROM YOUTUBE.

    So goddamit now I can't pull a fast one anymore and gotta continue working.
    Good news is that I might have a lead on why the pe source stopped building for me, and will tackle a fix next thing in the morning.

    New pe update eta son; dis rom isn't ded yet
    15
    Roses are red
    This rom is discontinued
    But fear not, another one will continue
    Pe sauces are broken
    My parrot has spoken
    Many fixes will arrive soon
    Jack-server is a baboon
    Ui lag has been fully* fixed
    This time hasn't been jinxed
    Gpu freqs are running normal
    Dual speaker won't be so abnormal
    October patch will be invited
    Perhaps more roms will come in bunch.
    For me it's bedtime
