[Samsung Galaxy S9 & S9+ Cross Device Development] Rainbow_Dash:

LineageOS is a free, community built, aftermarket firmware distribution of Android 9.0 (Pie), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Troubleshooting/FAQ:

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 CSB8 vendor and fw, and try again. This has been tested. It's prolly something on ur end.

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)
