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 guys, first of all, this is the best custom rom ever for our tab s3. Many thanks to Awesometic and team !
    I'm trying to activate gestures navigation that i remember can be found at settings > system > gestures > system navigation. In this rom i do not see this option. Can the gestures be activated ? I could not figure out how ... Thanks in advance !!

    .... Can the gestures be activated ?....
    Probably not implemented.
    Mine is on Nova launcher prime and I'm using its gestures.

    Long time no see. :)

    I uploaded the new version that contains the November security patch and fixed arrow keys working on the keyboard inputs.
    Yeah, sorry for it isn't a big update, I know there're lots of bugs remaining. 😅

    Currently I have been investigating upgrading our kernel as I said before.

    I did start the Android kernel studying to know what CAF based kernel or AOSP based kernel means, and how the other people merge the latest tags from the official repositories to the vendor-providing kernel base.
    And now I think I'm managed to know the very small piece of that Android kernel world.

    First, I found that there is no problem with using the Bluetooth keyboard on the stock kernel for LOS, which hasn't any patch including the upstream Linux patches and/or any tunes.
    Yeah, this is interesting, it can be small evidence that the current kernel is somewhat broken at least for the Bluetooth.

    My first plan was to migrate Samsung codes to the LineageOS MSM8996 kernel. But after a few weeks, I realized that it isn't for humans. There are so many flags and tweaks they put in. Even some codes are not marked whether this code is from Samsung.

    So I changed my plan, to get CAF tags onto the top of the CTD1 kernel that is the latest kernel base of the T825 model. Fortunately, I could merge some modern CAF tags successfully. But in that progress the camera got broken. :unsure:

    Then, I tried to merge the AOSP tags for getting the proper upstream Android/Linux patches and security patches. I could merge until early 2020, that is also containing 3.18.140 upstream Linux patches. But I couldn't merge the latest patches like the one just published last month. It makes the tablet not boot.

    I think it is quite hard work on our tablet because Samsung puts various un-listed patches onto the top of the 3.18.115 kernel but they didn't apply the upstream Linux patches. So, for example, when I merge the 3.18.116 tag to the current 3.18.115 kernel, I couldn't accept all the incoming changes because some files in the current kernel base are much more modern files. o_O This makes me get frustrated.

    But it doesn't mean it is impossible. Some people out there are doing this job now so there will be something more I don't know yet about the Android kernel development. If someone has experience or knowledge of upgrading vendor kernel, please join our Telegram channel and let's discuss that.

    Hello all.

    I uploaded the new LineageOS ROMs that comes with the new kernel.

    Probably the first seen noticeable change is the Bluetooth keyboard is fixed now. 😀
    And there are lots of improvements on that. I wrote the detailed information to the first post of this thread but firstly, I copied that contents here.

    ## About the kernel

    ### Update on 2021. 12. 3


    Finally the first release including my custom kernel is published, as of December 3, 2021.
    Now all the later releases will have my kernel. :)

    This kernel is based on CTD1 firmware, and I have done the following jobs so far;
    • Merged android-linux-stable/msm-3.18, which is including up to Linux 3.14.140 patches
    • Merged LA.UM.7.6.r1-07800-89xx.0 CAF tag
    • Replaced the built-in WLAN driver into the CAF one from LA.UM.7.6.r1-07800-89xx.0 tag, which is the latest version
    • Disabled most of Samsung-specific flags including TIMA, KNOX, RESTRICT, ...
    • Enabled F2FS file system
    • Added AutoSMP CPU hotplug feature and enabled by default for better battery consumption
    • Added AdrenoBoost and enabled by default for better GPU performance
    • Added Anxiety I/O scheduler for better I/O performance
    • Enabled TCP Westwood congestion window control by default for better network stability
    • Set CONFIG_HZ to 300 which is recommended in Android devices and it improves overall interactivity and UX with no power cost
    • Now the S-Pen palm rejection is implemented in the kernel rather than the Android frameworks
    • Maybe more..?
    But we have still some limitations.
    • It still uses the legacy camera driver from CTD1 firmware so unfortunately there are the same bugs on the camera as before
    • The screen on/off using a flip cover is broken for an unknown reason. The system recognizes how the flip cover status changed but actually not working
    • Cannot upgrade to the next CAF tag because of some old blobs we have, I believe
    • Maybe more..?
    This is the first version of mine, so there might be some more upgrades on later.

    I think the most meaningful thing about this job is now we can edit the kernel on the full Linux kernel commits.

    Enjoy. 😀

    @Awesometic great news. Thx very much again.
    Just downloading.
    Any, to you known, disadvantages from f2fs to ext4?
    I've read that ext4 is more stable.
    What do you think?

    Yeah definitely, EXT4 is the most stable file system for Linux so even the modern Linux distributions use that as a default file system for the root partition.
    I think F2FS is also stable nowadays and it is enough to use on a mobile device. In fact, 3.18 kernel doesn't get the latest patches since 3 years ago but fortunately CAF and AOSP sometimes added some patches on that.
    Yeah, this depends on your choice. Between relatively unstable but faster one and the most stable but a little slower one :)

    @Awesometic so being lazy I've just wiped System and Caches then flashed your new LOS which worked.
    As I undervolt (thought might reduce freezes) my device I don't think it's sense full to switch to a faster fs.
    I will use it like before to test if (probably GMS caused) random freezes still appear.
    If they don't I still can switch to f2fs.

    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. :)
