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
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?
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
Make sure TWRP has been installed and functional.

Initial release Boi
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: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?
