Why It dont have the google discover when I swipe right from main home screen? Could you add this into this rom?

Or any trick for that?

Thanks for your hardworking 👍
[Samsung Galaxy S9 & S9+ Cross Device Development] josip-k:
New builds are up :)
[Samsung Galaxy S9 & S9+ Cross Device Development] ilvipero:
Hello guys, I just created an account here in XDA as I wanted to reply and possibly help out.

Thank you so much @DeHuMaNiZeD for this great ROM. I have a few Samsung devices that are no longer supported by official LineageOS, and your ROM allowed me to enjoy Android12. 🤩🥳

So far everything runs well, and I really enjoy encryption out of the box. The only issue I am confirming is with sound quality with Bluetooth. Tested on a couple of BT devices paired to a Samsung Galaxy S9+. Same phone with other ROMs such as /e/OS or ArrowOS did not have this problem.

Cabled Music, Video, Calls: No issue

BT Music: Briefly stops and resumes. Happens between 30 and 90 seconds of continuous playback.

BT Video: Briefly stops and resumes, or mutes audio for a few seconds as video continues. With video happens all the time, and after failing and resuming for a couple of minutes, it sometimes disconnects BT device.

BT VoIP Calls: very similar to BT Video.

The issue is hard to describe. It sounds like if BT does not have enough bandwidth and starts dropping packets to keep up. And with heavier video or video calls, this happens much faster.

I am not an android developer but I do have a couple of spare devices compatible with this ROM. If there is anything I can do to help with testing, feel free to reach out.
[Samsung Galaxy S9 & S9+ Cross Device Development] josip-k:
I am aware of the issue, it will get fixed in the next release.
[Samsung Galaxy S9 & S9+ Cross Device Development] 0xdeadf00:
I have some problems with this build coming from the previous build of this ROM:

* OTA wasn't supported. Had to sideload via adb

* previous GApps weren't compatible (wrong android version!?). Tried with MindTheGApps 12.1 (not 12.0) which somewhat worked but some apps now claim play services are missing!?

Anyone had any luck using the new build with some GApps?

Also, I cannot revert to previous build due to "SPL downgrade" not allowed? Is there a workaround for going back to the previous version?

Thanks for your work.
[Samsung Galaxy S9 & S9+ Cross Device Development] AlexBurnout77:
Thanks so much!
[Samsung Galaxy S9 & S9+ Cross Device Development] Razuuu:
Wasn't supported because 19.0 -> 19.1
[Samsung Galaxy S9 & S9+ Cross Device Development] ilvipero:
Upgraded from: lineage-19.1-20220402-UNOFFICIAL-star2lte

to: lineage-19.1-20220412-UNOFFICIAL-star2lte

And now Bluetooth audio seem to be excellent, Thank you!

No issues found so far with this build.

Quick note. I was not able to do OTA upgrade from 20220402 to 20220412. I had to adb sideload. no problem with that, I just thought to mention it.
[Samsung Galaxy S9 & S9+ Cross Device Development] josip-k:
Thanks, i will look into OTA.
[Samsung Galaxy S9 & S9+ Cross Device Development] Fouer:
Wow, never had I hoped that there would be a A12 Los for our old s9 :) The last build had been working flawlessly so far for me, tho I second that OTA update did not work.

Thanks man, really appreciate the effort, I've sent a small btc donation as a token of gratitude.

P.S. Is there a way to enable double tap to wake-up the phone(show the lock screen)?
[Samsung Galaxy S9 & S9+ Cross Device Development] RJBPrime:
Bug Report (may be hardware related, maybe source related) Bluetooth doesn't seem to work for me in most if not all Android 12 roms I've tried, including this one. I go to turn it on, it stays stuck on turning on bt, then when you navigate away from either QS or in settings > connections > bt, then go back to it, it has turned off again. Tried with and without Magisk 24.3 installed as a zip immediately after installing rom, still happens.

Tried this rom (2022-04-12) with Lineage Recovery, and Project Elixer (v1.5) DerpFest 2022-04-15,, and ArrowsOS (both Vanilla with at first go NikGapps and the FlameGapps, and GAPPS) version 2022-03-17 with TWRP recovery. All were data wiped, then wiped system, vender, cache, dalvik, data, and internal between installs. It seems to work under official Android 10 firmware, if that helps. Haven't tried under Android 11.

Using an Australian S9 Starlte

EDIT: Beginning to think it's a bt hardware issue, as I don't usually use bt under stock, due to only having one other device to connect to, being a laptop, and it being slower than molasses to transfer files via bt.
[Samsung Galaxy S9 & S9+ Cross Device Development] utkuilmaz:
Hey I am kinda new to stock lineage, is there a way I can install microg? I already setup my device and forgot microg haha
[Samsung Galaxy S9 & S9+ Cross Device Development] ilfugiuliopascal:
Are bluetooth headsets working fine during phone calls? Apparently the unofficial LineageOS 18 ROM, based on Android 11, had some issues in this regard: The sound on the other side of the line was not very clean (microphone issue). The problem seems to have been solved in ArrowOS 12, which is based on Android 12. Since this ROM is also based on Android 12, I was wondering whether the problem has been solved here as well, or whether the fix is something specific to ArrowOS.
[Samsung Galaxy S9 & S9+ Cross Device Development] betonoias:
This is android 12.1 and maybe you should read the changelog too
[Samsung Galaxy S9 & S9+ Cross Device Development] ilfugiuliopascal:
I should have said Android >= 12, sorry.

In the changelog it is not specified if the problems solved on 2022-04-12 were concerning the speaker or the microphone. Since there were other bluetooth issues before, I felt the urge of asking explicitly here. On LineageOS >= 17 and < 18 the changelog says that the bluetooth is working fine, meaning that the bluetooth speaker is working fine, when the microphone during calls is actually not.
[Samsung Galaxy S9 & S9+ Cross Device Development] AlexBurnout77:
Hello! Has anyone succesfully installed Magisk? I can't get it installed. Please help!
[Samsung Galaxy S9 & S9+ Cross Device Development] teamacc:
It's pretty easy, just rename the .apk from https://github.com/topjohnwu/Magisk/releases to .zip and adb sideload it from recovery, just like installing lineageos.
[Samsung Galaxy S9 & S9+ Cross Device Development] vindeliker:
Thank you for this rom! I was on stock rom and installed this image two days ago. I like it very much.

But I have no NFC now. I can switch it on and off, NFC checker says it's available but, there's no reaction on any rfid pin or ID card. Anyone else? Thanks!
[Samsung Galaxy S9 & S9+ Cross Device Development] Razuuu:
This ROM does not support microG signature spoofing
[Samsung Galaxy S9 & S9+ Cross Device Development] niquedegraaff:
I installed it on my (Dutch) Galaxy S9 and it works ok, but there are some sound issues I think:

- Try screenrecorder from the top menu, choose with system sound and mic, and you'll notice that the mic volume is extremely low, you can barely hear yourself when you play back the recorded video.

- Playback of music has no low frequencies in the bottom speaker, the speaker is capable of producing lower sounds.
[Samsung Galaxy S9 & S9+ Cross Device Development] AlexBurnout77:
Nice troll, kid.

Hi! I'm trying to upgrade from LOS 18.1. Has anyone found a good solution for app data backups? I tried Neo Backup, but ended up wasting four hours because the app messed up.
[Samsung Galaxy S9 & S9+ Cross Device Development] teamacc:
It is literally in the docs on how to install, although now listed as "deprecated".

https://topjohnwu.github.io/Magisk/install.html scroll to the bottom.

Edit: this was supposed to be a quote of @AlexBurnout77

Mod edit: @teamacc I've inserted the quote for you. - Regards Oswald Boelcke
[Samsung Galaxy S9 & S9+ Cross Device Development] AlexBurnout77:
Hi. You're right. Sorry for being ignorant.
[Samsung Galaxy S9 & S9+ Cross Device Development] 9rowfin:
Hi there,

I just upgraded to 20220412 from 20220219 - Now I have no access to the internet via WiFi or LTE (SIM)?

I have obviously entered my home WiFi password, and it shows that it's connected, and have also enabled mobile data on LTE..

Is there something obvious I have done wrong when installing 20220412 via adb? Like I said, I had no issue with 20220219 - I only installed the updated ROM as it was available, and the fingerprint sensor stopped working (this now works again, but no internet!)

Thank you :)

******EDIT****** ALL IS GOOD - I tried using "Seedvault" in the attempt to not have to re-download everything,

and every app (besides FairEmail) would not allow an internet connection without reinstalling. Seems I am now good to go :cool:
[Samsung Galaxy S9 & S9+ Cross Device Development] lorenzomacdonald:
Can we use desktop mode in this rom with samsung dex dock?

When building yourself, it is possible to enable signature spoofing. microG works perfectly after building with SIGNATURE_SPOOFING set to "restricted".
[Samsung Galaxy S9 & S9+ Cross Device Development] Snoddy:
Is mobile data working on the ROM currently? Either LTE or 3G?
[Samsung Galaxy S9 & S9+ Cross Device Development] scarymoviesg:
Hi everyone. I am having problem setting up Work Profile via Intelligent Hub. It says "Failed to get token for google account". It is rooted with Magisk and I did not have this problem when it was running LIneageOS 18. Any help would be appreciated. Thank you, guys.
[Samsung Galaxy S9 & S9+ Cross Device Development] friscoboi:
I feel slow. Have been looking for that "Lineage Recovery" for S9 for over an hour now. There is no link. No luck searching the web.

How to get the "Lineage Recovery"?
[Samsung Galaxy S9 & S9+ Cross Device Development] teamacc:
Check the "Builds" link in the OP, choose your device, and pick (for example) lineage-19.1-20220412-recovery-starlte.img (in case of sgs9)
[Samsung Galaxy S9 & S9+ Cross Device Development] kot7k:
Hi,

Has been some time since latest update, will you continue updating it?.

Also, is there any reason that prevents you from applying to be official lineage? it would be very nice for many users that are holding back just for being unnoficial.
[Samsung Galaxy S9 & S9+ Cross Device Development] Jamesatmaisonverre:
An excellent ROM, works perfectly. Thank you. Mind the gaps would not flash because it could not mount the partition but I was able to use nikigapps instead. Great work, thanks.
[Samsung Galaxy S9 & S9+ Cross Device Development] logz56k:
This rom looks amazing! I have one question though. Does NFC and Tap to pay work??
[Samsung Galaxy S9 & S9+ Cross Device Development] logz56k:
Hey all. I am having trouble flashing this rom with the Lineage OS Recovery. Every time i try it comes up saying "Failed to update ODM Image". Please can someone help me out. Thanks.

[Samsung Galaxy S9 & S9+ Cross Device Development] s7droid:
@DeHuMaNiZeD is this rom EOL?
[Samsung Galaxy S9 & S9+ Cross Device Development] Vinz404:
Is this compatible with G965N (star2lteks)?
[Samsung Galaxy S9 & S9+ Cross Device Development] Daniel23420:
Will you post an Android 12 version for s9 Snapdragon 845? That would be amazing! Kind regards, Daniel.
[Samsung Galaxy S9 & S9+ Cross Device Development] icantintorecovery:
the recovery image for galaxy s9 is wrong or corrupted because neither odin nor heimdall let me flash it, 7zip gives a wrong file error and doesn't compress it, please fix it

Edit: thanks now it works
[Samsung Galaxy S9 & S9+ Cross Device Development] TheHDR:
I apologize if this has been answered or asked before, but is there a way to re-enable the feature that lets you hard press the screen to go home?
[Samsung Galaxy S9 & S9+ Cross Device Development] kentatsu2:
Hello, its been a while since the last update. I guess you won't be updating this build anymore?
[Samsung Galaxy S9 & S9+ Cross Device Development] Racinghart91:
Does dual sim work with any aosp rom ?
[Samsung Galaxy S9 & S9+ Cross Device Development] Cecillatour:
Yes. It worked for me with Pixel Experience and Arrow OS on Android 11 and 12. It worked also on Lineage OS 18, on Android 11. I did not test Lineage OS 19.
[Samsung Galaxy S9 & S9+ Cross Device Development] Racinghart91:
Thanks man! I am going to try this one.

Is it good for daily use ? I want to flash this on my work phone.
[Samsung Galaxy S9 & S9+ Cross Device Development] Im1Random:
Everything working fine so far. But I have 2 questions.

1. Is the Image still being maintained? There wasn't an update since 3 months now.

2. Why so hostile against TWRP? Using it for years now on my Galaxy S9 and never had any issues. In comparison to the LineageOS recovery which has nearly no features and for absolutely everything you require a pc... Like why connect to a pc and sideload it via adb if you could just flash files on the go from a usb drive?!
[Samsung Galaxy S9 & S9+ Cross Device Development] zozuka:
Does dual SIM dual VoLTE work?
[Samsung Galaxy S9 & S9+ Cross Device Development] l4jos:
Im using this rom too. It works well. The only thing I worry about is the heat when browsing alot (chromium/firefox/any browser).

@Im1Random devices without external SD require a storage media to install from, hence the ability to sideload on PC.

You don't need LineageOS recovery to use this ROM. I was able to update the system last time when I used this ROM alongside TRWP.
[Samsung Galaxy S9 & S9+ Cross Device Development] zozuka:
Do you use it with 2 SIMs? Does VoLTE work on both SIMs? Do you mean you updated the factory ROM (Android 10) to LineageOS with TWRP? If so, could you please copy here the procedure you followed. Thanks a lot.
[Samsung Galaxy S9 & S9+ Cross Device Development] l4jos:
I use only 1 SIM. VoLTE works anyway. Install SAMSUNG_USB_Driver_for_Mobile_Phones. Reboot. On stock ROM (samsung's android 10) you must enable developer options and enable OEM unlock, and reboot into download mode. Connect USB while in Download mode. Launch Odin on your PC, browse/download TRWP .tar into "AP" and uncheck auto reboot. Click start. If you notice the green box in Odin "PASS", immediately reboot into recovery by holding volume up + power + sidebutton until you get in TRWP. If you noticed default Android recovery, repeat the whole process one more time.
[Samsung Galaxy S9 & S9+ Cross Device Development] abhic7:
ok I am confused by this part

*****

Flash lineage recovery

Only the provided lineage recovery will be supported,

using TWRP might result in a possible data loss!!

If using Odin rename the lineage recovery image for your model to recovery.img and add it to a .tar archive using e.g 7zip.

If using Heimdall use: heimdall flash --RECOVERY recovery.img --no-reboot

*****

I have renamed the file to recovery.img

then i use 7zip to compress and transfom to .tar

use the file in AP in Odin

press start

Oden crashes ...wtf

Has anyone solved this ?
[Samsung Galaxy S9 & S9+ Cross Device Development] zozuka:
Thanks. In the beginning of this thread TWRP was discouraged to be used due to possible issues (see the previous post). Has this risk been eliminated? Do you have it on S9+ dual SIM phone (G965F)?
[Samsung Galaxy S9 & S9+ Cross Device Development] zozuka:
Could someone please confirm that this image supports dual SIMs?
[Samsung Galaxy S9 & S9+ Cross Device Development] Redmanha:
Yes, it supports dual-sim (on my SM-G965F). I tried it with T-Mobile Germany and O2 Germany.
[Samsung Galaxy S9 & S9+ Cross Device Development] zozuka:
Thank you. Did you find this image better than the stock ROM? Was there any functionality on the S9+ that was not working?
[Samsung Galaxy S9 & S9+ Cross Device Development] Redmanha:
I didn't encounter any props - all worked good for me. You can get GooglePay working with Magisk/Zygisk/Hideprops to work too. The only thing (that is for all custom roms on most devices) is Widevine - it's only L3 and i didn't get it to be on L1. This is the only one what is not working.
[Samsung Galaxy S9 & S9+ Cross Device Development] zozuka:
Thanks. I think I'll give it a try and say good bye to the stock ROM with all the bloatwares eating the battery. Have you used TWRP for installing or the method with lineage recovery described by Dehumanized in the beginning of this thread?
[Samsung Galaxy S9 & S9+ Cross Device Development] Redmanha:
I used the recovery from OP / lineage-recovery, worked pretty good...
[Samsung Galaxy S9 & S9+ Cross Device Development] l4jos:
This happened to me as well, not sure anymore what exactly solved it. Try (re)install samsung drivers and another odin package, like this two worked last time. Please quote or like if this helped you, so it helps other developers.

SAMSUNG_USB_Driver_for_Mobile_Phones

Odin3 v3.14.1_3B_PatcheD
[Samsung Galaxy S9 & S9+ Cross Device Development] l4jos:
s9+ star2lte

It's not eliminated whatsoever, I think it depends on more factors.
[Samsung Galaxy S9 & S9+ Cross Device Development] Racinghart91:
Yo,

You say VoLTE works but it doesnt work on any AOSP rom on this device right ???

Its the only thing stopping me from installing this.
[Samsung Galaxy S9 & S9+ Cross Device Development] shakma66:
Hello, even though I anticipate I'll get heavily reprimanded for this but is anyone in here willing to provide a step by step breakdown of the instructions given by the OP for total beginners like me? I haven't ever done anything like this before. I own a Galaxy S9 (SM-G960F/DS)

I have so far far downloaded "lineage-19.1-20220412-UNOFFICIAL-starlte.zip" as well as "lineage-19.1-20220412-recovery-starlte.img" from the link given under "downloads: -builds" in the very first post of this thread.

Furthermore I have downloaded and installed "Samsung_USB_Driver_v1.5.60.0" as well as downloaded and unpacked "Odin3-v3.14.4".

But the first step in the 2nd post of this thread

"Installing LineageOS for the first time

1. Flash lineage recovery"

Is already not 100% clear to me.

I am assuming it does mean to take the file mentioned above "lineage-19.1-20220412-recovery-starlte.img" rename it to "recovery.img" to be taken then packed it into a ".tar" archive (I am using 7z for that) right?

Then I start up "Odin3_v3.14.4.exe" as an admin. But after that it is unclear to me as of what exactly to do.

I would be rly thankful if someone could at least provide me with a link which guides total newbs like me through this process.
[Samsung Galaxy S9 & S9+ Cross Device Development] Racinghart91:
Put your phone in download mode, connect to pc, open Odin, transfer the file to the phone, auto reboot off in options, flash.
[Samsung Galaxy S9 & S9+ Cross Device Development] l4jos:
@Racinghart91

It depends on more factors, this part is still under development

But Pixel experience is AOSP so I would give it a shot:)

[Samsung Galaxy S9 & S9+ Cross Device Development] ElPakoTech:
Hi, thanks for your works. I build from your sources and it works really well.

Recently, I updated lineage from your last updated sources but I lost my WiFi which is failing to start. Do I need to flush data/vendor from recovery as it seems that the WiFi driver change ?

Or does someone have WiFi issue too with the last build ?
[Samsung Galaxy S9 & S9+ Cross Device Development] murderbee:
I installed LineageOS last week on an S9. Worked perfectly. Thank you for providing this software and documentation!

Today I received an update notification, downloaded the update, tapped "install", "preliminary something" progress bar filled, then I got an "install error". Do I have to manually sideload the update or should it work with the built-in updater?
[Samsung Galaxy S9 & S9+ Cross Device Development] Neurotical:
I also encountered a failure of WiFi to enable after compiling the latest version of this rom. The WiFi toggle does not stay on and WiFi doesn't work.
[Samsung Galaxy S9 & S9+ Cross Device Development] BlueStarZero:
I'm having this exact same issue with my S9+. Any advice? What should we do?

Also, has anyone been able to successfully install MinMicroG on this ROM?
[Samsung Galaxy S9 & S9+ Cross Device Development] josip-k:
To everyone that's doing self builds, your wifi is failing because you use the wrong kernel source which does not use the updated drivers. As for updater, i am not sure, but i did try updating manually from the release before and that part worked.

Thank you very much! Works like a charm.
[Samsung Galaxy S9 & S9+ Cross Device Development] Ferexio:
Hi, I wanna ask about NFC, because I would like install LineageOS 19, but for me NFC is very important, and I would like know that how chance is that NFC will be working because I am only paying using Google Pay. I would like know too how is about internet, phone speed and battery drain - how much draining power from battery. I need speed, and stable rom so I would like know your (forum members) opinion about this rom. If you want then please tell me this informations in private message. Thank you a lot!

Regards
[Samsung Galaxy S9 & S9+ Cross Device Development] l4jos:
@Ferexio NFC works, speed is best, battery last a bit shorter, but thats because Android 12.
