Hi, I've installed the ROM on my SM-T825 through TWRP, rebooted the tablet and everything was great.
Then I started configuring it and I got to the point where it asked me to set a protection.
I chose fingerprint + PIN and, when I clicked "confirm" after typing my PIN when it requested me to confirm it, the settings app crashed.
A message popped up saying "the Settings app doesn't work."
I clicked "close app", turned off the tablet and, when I tried to turn it on for the second time, it got stuck in a bootloop.

P.S.: I can't access recovery
 
....... , when I tried to turn it on for the second time, it got stuck in a bootloop.
P.S.: I can't access recovery
Download mode still accessible?
If yes it might be worth trying to just flash TWRP via Odin and, when rebooted to recovery, to make a clean flash (incl format data) from SD but this time with LOS19.1 which imo is much better anyway as being more stable.

I somehow managed to access recovery and reflashed the ROM.
Now everything's fine and the tablet is usable, but I still can't set a lockscreen.

I have a bug report concerning WiFi display/screen casting.

It worked fine in the version 20211219 in which you first fixed WiFi display (tested with a MS Wireless Display adapter). Unfortunately, something seems to have broken the functionality in the next version, since both the February and March versions cannot establish a connection anymore.
I just noticed recently because I hadn't needed the screen cast for a while, but with teaching starting again, I now had to revert to the December version.

I tried to grab a log of the connection breaking down, maybe this could be useful. I'll upload it later from the tablet itself. Would be great to get this working again!

Here's the log around the time I tried establishing a connection.

ps: What the hell?!?! I attached the log file four times on two different browsers, upload - save, and then they still don't show up in the post?

Big problem with the latest version: random reboots (without using it) until the tablet (825) is definitely dead! Sometimes running out of battery completely, sometimes not. To restart it, power supply inserted, power+vol-+home....... Any kernel-related issues?

Hello all,

I updated LineageOS and HavocOS and uploaded them to the forum.
In this update, besides the latest Android sources, I added some more fixes including the fingerprint recognition issue.

Please check the update changelogs, thanks. :)
Thanks for the update! My wifi tab s3 was having black screens after trying to unlock the screen from sleep on the previous version. Seems to be fixed now.

Thanks you so much.
I made an update via TWRP, straight flashed without any wipe.
Everything is working fine, before the update I had sometimes that black screen after fingerprint reading, now after a few days that failure is away.

    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?

    I meant a lock screen method like fingerprint, pattern, and pin. :)

    Anybody using this as a daily driver? Is it possible to run S notes with this ROM? Thanks in advance for answers.

    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!

    I got your answer already. Thanks again! (It's Yes I suppose.)
    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.

      • You will type `yes` to do that.
    7. Flash the images.
      • If you're going to install GApps or something, you have to install the LineageOS first.

    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
    • Unlocking the lock screen can make tablets not usable sometimes (black screen)

    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. :)
