Just Updated (dirty flashed) the previous version to the New LTE Version one with TWRP 37_9, cleaned caches, too. LOS start hangs since about 45 min at that circle running from right to left. Seems like the update broke the System.

After my Battery ran out, the tablet only Sees and starts TWRP. But that will not neither start. What a pitty. Looks like a totally New restart from scratch with the latest Samsung original ROM.

Thank you for answering.
Any ideas if the fix will be patched to Android 13 or should i just downgrade to have it working? If so, best way to do so please?
I downgraded, Android version and patch-level are two different things anyway. If you have lower Android Version but newest patch level, then you are safe. This rom will do the job for everything.

@Awesometic first of all many thanks for your great work! I appreciate your hard work!

Don't know if this is already a known bug but I have issues with streaming calls (not only cellular) via bluetooth. It is only working via loudspeakers (calls only use one speaker too, is this correct?).

As soon as I want to call someone with a bluetooth headset I do not hear anything of the call. (Tested with several devices) - while streaming music to a BT box works flawlessly.

If this could be fixed it would be amazing. Would pay several coffees for that!

I installed lineage-18.1-20230510-UNOFFICIAL-gts3lwifi.zip with NikGapps-core-arm64-11-20230609-signed.zip without a reboot between them and it works.

Can also confirm that the microphone now works on Zoom calls, which is wonderful. The green bar and colour distortion is still there, but I can live with that. :)

EDIT: Minor formatting changes

Hello all,

I just uploaded the new LOS 18.1 ROMs that synced with the latest LineageOS source codes.

It doesn't include any specific fix by me, but it'd surely be more stable than the last one.

It will appear on your system updater since now we're using OTA updating supported ROM, so you can update it on your device right away. If you can't see it, please let me know.

And as always, I read all the comments and have been trying to fix the known issues. Just let me know by the comments or Telegram :)

Installed is from a stock ROM, nicely installed in the TWRP (thanks) and the ROM, however it seems the tablet doesnt' always wake up from sleep. The only thing that seems to resolve that is putting it back in bootloader mode and reflashing TWRP. Any tips?

    Successfully installed the 2023.9.19 OTA patch on my SM-820. Everything seems to work except for the known issue of the green bar in the video of zoom.

    Thanks for the update as always!

    ...Seems like installing magisk is not enough
    Magisk had to be flashed in TWRP as zip and installed separatly as apk as well when I used that ROM, before switching to 12L.
    After first start it patches the boot.img and after a reboot I had root.

    # LineageOS

    LineageOS is a free, community built, aftermarket firmware distribution of Android 11, 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.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

    # Known issues
    • Camera somewhat buggy
      • Sometimes the camera doesn't work after booting. You can fix that back by just rebooting
      • On webcam chat apps, there is a vertical green bar and the color is not properly displayed
    • OTG drives may show nothing even if it mounted
    • The side button on S-Pen is working but you must use the proper application that can handle the button event

    Hi all,

    Finally, I can take a picture with my Tab S3 :)

    But still, there are some annoying bugs about the picture resolution, a flashlight behavior, ... but yeah it is usable when I take something using slightly lower resolution without the flashlight.

    Also, for now, both the LOS camera app and Snap camera are not working well while Open Camera and Google Camera seem to be working well.

    For now, the major problem is that if I use a flashlight in the camera app at least once, the overall GUI animations slow down even I closed the camera app.

    So, when I publish the camera fixed version, at least I will fix this most bothering thing even though I can't fix it all for the camera.

    Hello all.

    I uploaded the new version, including fixing the power-off mode charging.
    I'm using the LPM binary that is from Samsung for the power-off mode charging. When you plug in the charging cable while the tablet turns off, you can see the original charging screen you might see in the stock firmware. :)

    And I tried to fix the Bluetooth inputs and the OTG drives issues but I couldn't. I can reproduce these problems but I cannot find how to fix them for now. But I can confirm that the wired input devices are working such as a keyboard and a Playstation 4 controller.

    Please check out the first post of this thread. :)

    Great news here. The next release will include the fully-working quad-speakers. :D
    And I also have implemented the audio rotation codes for the screen rotation.

    Actually, I already have used it for about 3 days, and I think it looks working flawlessly.
    And, for the alternatives of the Dolby Atmos, I have tested with the Dolby Digital Plus module with Magisk and I can say that it is awesome. :cool:

    The new release will be uploaded before this weekend. :)
