Nightmare started when I sent my tab to Samsung service center for cracked Screen replacement, the formatted it and reinstalled latest Android 9 stock OS (1.5 years back). Since then OEM unlocking option disappeared from Developer's option section.

Samsung repaired damaged screen and re-flashed Android 9 stock ROM. Since then OEM unlocking disappeared.
Before each try I waited for more than 7 days.
One more observation- When I set ANY previous date and try to check system update for FIRST TIME, there is an error message appears as device failed to register on server.
Now again I will try your method and update here. Hope this will work.

I've got a weird issue with Skype, the local self-picture looks fine but the one sent to the other person has colour issues (some sections of the picture are in B&W; white balance?), The audio & video settings in the app are missing. Those settings are also missing in Skype on my S8 which is running Lineage 19, but the sent video looks OK there. Anyone else have this issue/suggestions?

I notice the 19.1 ROM for the t820 now lists the camera as working (I'd used it earlier but had to bail out as the camera was not working at that point); can anyone confirm whether Skype works properly on there?

Thank you very much for the ROM Awesometic! Just flashed it and everything works great on T825 so far. I just have a quick question: "hardware encryption does not work", means that I should not try to encrypt the tablet, right? Will this feature be able to be added in the foreseeable future?

Right, that means we couldn't use disk encryption on Android settings.
It supports general encryption options in the lock screen settings.

Currently I don't have a plan to support that feature since there are many things that should be done with priority to that. :)

By the way, I updated the encryption setup for this device tree recently, so if you have a backup of the current state you may try the disk encryption. If it doesn't work, probably it will fall into boot loop then, you can restore the backup.

Thanks for the quick reply! That's exactly what I wanted to know: I am not aware of the difference between hardware encryption and general encryption, but that doesn't matter. I obviously meant the general encryption, which I have now tried, but indeed it ends in the boot loop. Should I just try again until it works, or is there no chance?

Oh no... sorry, I misunderstood again. Now I have it. I tried the disk encryption, it doesn't work as I said. But then what is the general encryption in the lock screen settings?

S Note is a Samsung dedicated application. I don't know if it can run on non-Samsung devices.

S-Pen is working on third-party note applications but you couldn't use its full functionality as much as the Samsung devices do.

Hi @Ilja Repin,
a few weeks ago I managed to fixed hardware encryption. Unfortunately I forgot to publish my changes after testing... So I have only my compiled version for now... 😅
It is based on the sources mentioned in the first post, my changes for device encryption and I disabled debugging by default (can be reenabled in settings).

Here is the link to my cloud: https://1drv.ms/u/s!AgBELbH5Ycnt0RKSPGXy2r0FXd_i?e=F4OVNL

Of course all credits go to @Awesometic who did a very good job with porting LineageOS!

    Yes. If you are on the latest build, you can dirty flash because the sources are nearly the same. 😉

    I hope you have the LTE version of our device? Otherwise this image would not work. I have not build it for the WIFI version up to now.

    # 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.

    9. Done.

    # Known issues
    • 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
    • Fast-charging won't work properly, it sometimes works but most of the time it won't
    • Sometimes turning on the flashlight via the quick panel doesn't work after using a camera app
    • Using a camera app may cause reducing the UI performance on a launcher app
    • The tablet rarely reboots with a GMS related error

    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. :)
