No sorry, freezing is one of the most annoying bugs :)
I glanced at your logcat and yeah, that crashes by the GMS application runtime. It also says "Not allowed to start service Intent".
So, maybe you're right, I think it may be a application problem, which is related to the GApps.

Sorry for not helping you, but if you face a similar problem and it is quite weird, please let me know.
It has happened to me too, but it's very infrequent so I usually just force reboot and go on
 
Just changed to 18.1-20210901 2 clean installs, does not run well at all on my t820. freezing, crashing and very slow overall.
Do you have a link to 18.1-20210813-UNOFFICIAL-gts3lwifi. This version was nearly perfect for my device
Have you fully formated data with TWRP and gone in ADVANCED WIPE and checked everything except SD Card?

I have a T820 and working flawlessly.

Yep, just did it again for fun.... only way to get into twrp is to go download mode and flash it from odin. Button combo brings up recovery booting, set warranty bit:recovery then black screen stops responding. Can then access download mode and flash ap again.
 
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! and thank you for keep working on the issues 🙏🏻
 
..... the new version, including fixing the power-off mode charging.....
Just trying it out.
Thx very much for your work and time.
Powered off charging info and start are working.

User info: contrary to the version before only a clean (incl "Fornat Data") made it possible to install on my T825.
Data restore made all as it was before.

hey man, you're an absolute legend. thank you for donating your time and talent to this. it might be worth way more than you'd guess for some people, i know it is for me. I wish you everlasting health and happiness. since wishes don't mean much please keep your username and online identifiers consistent so those of us that can't reciprocate properly right now, be able to do so in the future.

anyways the new release is great, as usual, slight problem tho i can't get it to boot with magisk. everything seems okay besides that.
thank you again
cheers

For my T820 it worked fine without "Format Data". Charging works now exactly as it used to be with stock rom. September-Patch is included :)
@Awesometic : Thanks again for your great effort! For me everything is finally perfect, I am so happy with my tablet now :)
 
@Awesometic: Will you be able to fix the issues I've described concerning secondary non main/admin users?

I have a plan to fix them too but not for now, sorry. I didn't try to fix that issue yet. 😅
After fixing the more commonly faced issues like OTG drives don't show anything, I will try to fix that.

Thank you for saying encouraging words 😀
I'm using Magisk with my LOS. Any clues why it can't boot?

Having latest rom now for 2 days, lockscreen-freezing now occurs very often on my T820 (with prevous rom it was very rare). Just flashed rom and gapps. Anything what I can do about that? I know there were previous posts with freezing errors related to GMS application. I now have to force reboot with power+volume down really often.

First of all, I would like to appreciate Awesometic for the amazing work that he do on this ROM. Your professionalism and enthusiasm reflects in the countless hours that you put into the project to ensure it see the light of day. Your self-motivation, dedication and diligence are an inspiration.

I've installed this ROM today and it is running very nicely. I thought, this tablet won't see any ROM development and will be forgotten but you Awesometic is GOD sent to us all tab s3 owners. I wish you all the very best.
 
Hey Awesometic, really thanks a lot for the ROM!! It works flawlessly for me on my galaxy tab S3 LTE 😁 the battery is good, the performance of the tablet is A LOT better than the stock ROM and also it's awesome to not have all the bloatware installed!

The only thing that "ruins" a bit the experience and makes me want to go back to the stock is sound, the quad speakers work, but the sound is not really the best, it sounds like it's a phone speaker compared to the stock Samsung UI. I tuned it a bit through audioFx presets, but it lacks all the surround sound that you had with Dolby Atmos, the highs are tingly, there's no bass at all and the overall sound is not equalised well.

Would you be able to extract Dolby Atmos or its settings? That would make this ROM the BEST CHOICE, and better in every aspect. Anyway, other than that, this is already a way better experience than the stock. Congrats and thanks again!!

It's already the best choice, you can install Atmos with magisk

    Hello all.

    Thank you all for all the feedback and review. :)
    I was so busy for cleaning up my ordinary jobs first so I couldn't reply to your comments. Sorry.
    But I read all of the comments and now I can collect the major issues that can be found so far and now I started to think that the kernel should be upgraded.

    I'm not sure but the LineageOS guys can port the Samsung codes to the upstream Snapdragon kernels, so it should be not impossible for us.

    As always, I'm not sure I can but currently I'm trying to port them to the LineageOS kernel. This can be abandoned so please don't expect too much. ;)

    And, before that, I'm suffering from the "not waking up after fingerprint recognition" problem. It is so annoying... :cautious:

    Hello Forum,

    wanted to leave my feedback here.
    I have the T820 - so only WLAN - and the device currently runs well.
    - No GApps installed, only F-Droid and Aurora-Store.
    - All hardware buttons work
    - Camera works, just no 2160p video possible > I have the same problem with my Galaxy Note 8 as well
    - WLAN, Bluetooth and GPS work
    - Battery lasts several days
    - Brightness sensor, gyro sensors work fine
    - All speakers work
    - All LineageOS standard apps work without problems
    - SD card (32GB) is recognized without problems, speed is only very slow for data transfers
    - UI is a bit sluggish from time to time, after closing all apps it's ok again

    Up to here already respect for the work :)
    Hope there are also diligent updates.

    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.

    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. :)

    I installed it from the link in the first post with OpenGapps Nano (also from the first post), and so far so good.
    This is really much much faster than the "Tweaked" ROM! It feels like a new tablet.
    I don't use the camera, so for me it’s already very usable. I didn't notice any problem with audio. There is only sometimes a short popup appearing (a few milliseconds) and disappearing. Also, if you enable "Trust" it complains about SELinux and some stuff.
    Anyway I will keep this fast ROM, great work, thank you!

    EDIT: There is also a notification saying : "Serial console enabled. Performance is impacted. To disable, check bootloader" which i didn't understand the meaning...

    Thank you for enjoying this ROM. :)

    You're right, audio has a little problem yet. I have a plan to fix that, but it will be after trying to use the Samsung binaries to fix the quad-speakers. If using Samsung binaries doesn't work, then will try to fix various issues with the bottom speakers.

    And you can disable the alerts from Trust app by its settings.
    The "Serial console enabled. Performance is impacted" message probably is by a kernel or bootloader problem. I can't sure, but fixing this may be quite the last part of my LOS 18.1 project because it seems not affects the performance actually. If fixing this is pretty easy than I thought, I will fix that promptly.

    You are so good! Thanks so much.
    I do have 2 of the WiFi tablets and will test after my holiday.
    The original firmware is really crap and so slow, hope that this is faster.
    The only problem is I need it as daily driver, but will make a complete backup.
    Greetings from Bavaria

    Enjoy. :)
    I strongly agree that the stock ROM is quite slow than it supposed to be. Snapdragon 820 with 4GB RAM should not be slow like that. Even that is on Android 9. This is one of the strong reasons why I started the development for LineageOS 18.1.
    I really hope this ROM works like a charm on your tablets too.
    And I'll keep updating this ROM until it is really usable without any major issues.
