Thank you, can you tell me the Patch level of the roms?
I'm sorry but I have no idea. I built them on 12 September, using the latest LOS code and the latest code from @Awsometic's git repos on that date. I no longer have access to the source used in the build and, as I stated in my original post, I don't own one of these devices, so I cannot run the ROMs to find out.

Hi,
One short question. I install the Rom more than six month ago but since then i got no Update from the internal Lineage Updater. Did i something wrong?

I'm not sure but I guess this works only for official LOS ROMs.
I always on any device install manually to reduce errors/failures.
Then I can decide by myself if I update dirty or clean.

    # 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.

    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. :)

    Hello all.

    I uploaded the new versions of HavocOS and LineageOS.
    Now we have Feb. 2022 Android security patch.

    And I added, changed quite many things to improve stability and battery life, thermal management.
    While I was experimenting I committed many things to the device tree and the kernel.

    Consequently, it looks like better than before in terms of thermal at least. Now some units in the system manage the CPU frequency smartly, which means if the device's temperature gets so high then it reduces the CPU frequency a little bit to cool down the device.
    This sounds like it may affect the overall performance, but for me it works very well so far. Yeah, we need some more tests.

    And I think I fixed the hotspot working. But I don't have a sim card for a tablet device available so I need feedback from the real user. Please let me know the results. :)
