For anyone other than literally only me wondering, lsposed coupled with gravitybox r can also enable the on screen navigation bar with no issues...
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] LedgendaryEpics:
Was this part of the new update?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] KL643:
Just installed this ROM (after several years of not flashing anything) on my S3 825 and besides some "hickups", its running smooth and fast. First I installed TWRP from the other topic and than the ROM and gapps. Only rebooting to TWRP doesn't work, I need to flash it again with Odin each time (must be doing something wrong here I guess..)

My 2nd hickup is Play Store certification (not certified). Anyone know how to bypass the easy way? TIA

Edit: I also get random restarts (after switching user) which results in boot loops)

Edit 2 : started from scratch, installed HavocOS ROM and all works fine now :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] kermit1502:
How do i configure the s Pen Button? There was a menu in Stock rom, when i pressed the Button...

Greetz Daniel
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Sorry mate, no chance as Samsung hides s-pen drivers from custom ROM developers.

Button doesn't/won't work other than on stock.

Nor does Notes and some other Samsung stuff.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] kermit1502:
Thx for the Info
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Yeah, sounds interesting. It is worth giving it a try with the new vendor + kernel implementation. 🤔
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Thanks for the report.

1. An installation error with a game? It should be fixed because it was handled by the kernel. If it is, if you can write a simple instruction to reproduce the problem then I will test on my side.

2. Hmm, then maybe OneNote hides the stylus pointer. We cannot control the pointer visible for an application.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Yeah, That option is now available from the last release.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
As far as I know, this could be hard to get certificated in this LineageOS (not mean the official one). But yeah, in HavocOS it is simply solved with Magisk hide. Seems they put something in the frameworks.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] KL643:
So that's the way to go for me now :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Siddhartha Valmont:
Thank you very much for the 2021-12-19 update @Awesometic !

Finally was able to reinstall games on my S3 !

You're the best !!!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] NullCode:
;P good luck
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MacStache:
Had to create an account just to thank you for this! Managed to breathe new life into this old tablet of mine. Everything works smooth and all the lag is gone.

I had some issues with OpenGApps in the beginning, as I got stuck into a "Checking Updates" -> "Getting Info" loop with the setup crashing all the time, but got past it by not connecting to a network at first and copying my account to the tablet from my phone. Then I had to update everything (Most importantly Android System WebView, which produced some errors at first) and after that it was smooth sailing. So no real errors from your work, really.

Everything I need works now. So thank you for your work!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Some options like checking updates will not work, it may keep trying to find the server and the packages. It should skip that step after some tries but sometimes it can be stuck because of unknown reasons. 😅

For me, I'm using NikGapps these days, and it hasn't some additional steps on the setup wizard. It allows me to test slightly faster and also works great.

Just for your information. 🙂
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] CosZ:
The battery life is very good, almost like when it was new. With the original software from samsung the battery lasted for 4 days with light usage and battery was continuously draining, now over night is only using 1%. AptX is working after the last update and can listen again to music with the headphones.

It is HavocOS better with encryption and selinux, at first install I did not read very carefully that encryption was not working and had to reinstall.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] roesja:
A very big thanks to you! My Samsung Galaxy Tab S3 was suffering from freezes / spontaneous reboots. Tried factory settings, clearing cache, recalibrating battery etc.. In the end I tried flashing this ROM and works now 2 days without freezes! (Not sure if it is the rom, or the complete reformat in TWRP, but just happy to have my tablet back!). The only issue I have encountered so far is that Keepass2Android does not recognize the fingerprint reader (Database settings - "No biometric hardware found"). This did work with the stock rom. The fingerprint sensor however _does_ work when unlocking the tablet itself.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
Are there detailed instructions on how to install this somewhere? I see some instructions on the first page, but they are pretty high level and assume that one knows how to unlock the bootloader, how to set up and use Odin, etc.. Is there something with more detail?

I consider myself to be pretty computer literate, but the fact remains that I've never installed a custom ROM before. I did root an android device once, but that was several years ago.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
As ROM threads implicate that TWRP is already installed (as otherwise you can't flash a custom ROM) you have to look there first.

For instance follow these instructions to flash an old version and update afterwards TWRP to latest version by @Awesometic or use this to go directly to latest version before carrying on to flash any ROM whichever suits you.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
Well, I started to try to install this, but ended up aborting fairly early in the process because I got spooked and really would rather avoid bricking my device.

After I typed "adb reboot bootloader", my device reboot rebooted to a screen where it said "Downloading…Do not turn off target".

Thinking that was normal, I proceeded to type "fastboot flashing unlock", but I just got a message saying "waiting for any device". I did some googling and saw a few different possible solutions. One thing I was going to try doing was updating my Android USB driver on my PC, but I couldn't find my device in device manager to update it. At that point, knowing I was nearing the point of no return, I just decided to reboot the device and give up for now.

We'll see whether I get the courage to come back to it at some point in the future.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sebmue:
Wow - this changes everything, at least for me. This tab feels like a new device now - perhaps not as fast as todays tablets, but finally without this "extra 3 seconds" it took for opening or reopening apps. Awesome. Great. Thank you - and happy new year!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
In that mode you can flash TWRP using Odin or Heimdall.

Where did you read this command for Samsungs?????
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
It wasn't a Samsung-specific site; it was a more generic site for Android devices in general. One site was at https://www.droidwin.com/unlock-bootloader-android-device/, but I recall other sites gave similar instructions. That said, none of them were samsung-specific. I'm guessing I can skip those steps then and proceed directly to Oden once I get to that screen?

If I do try again, does Oden directly upload all three images to the device (twrp-3.6.0_9-0-gts3lwifi.img.tar, lineage-18.1-20211219-UNOFFICIAL-gts3lwifi.zip, and open_gapps-arm64-11.0-stock-20211217.zip)? Or do I need to manually copy the files to a specific place on the device first?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
You didn't really read what I suggested to do in #315?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
Actually, I did, and in fact I read those instructions before I made my first post. Unfortunately, those instructions assume that I already know how to unlock the bootloader and use Odin, hense my initial post asking whether there are more detailed instructions somewhere.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
Well, I eventually got it installed, but then it got stuck during initial setup, but wasn't able to get through the initial setup.

When I booted up after installing both LineageOS and OpenGApps, I got the following

Getting your tablet ready...

Chose my network

Copy apps and data: Chose "Don't copy"

Just a sec...

Checking info...

Then I got a black screen.

After a while, I was able to get it back by pressing the power button, but then it just went back to "Checking Info", and then the black screen again.

Tried this with both "Stock" OpenGApps version and "Nano" version.

After struggling with this for a while, I gave up and re-installed the stock firmware (which was a bit of a challenge in itself).
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] xpil:
I think the mistake you have made was that you flashed the ROM and opengapps together. The way to go is to flash the ROM. Then boot the tablet. Then reboot to recovery and flash ngapps for Android and 11.Then reboot the tablet again and follow the instructions. If you want root then you reboot it in recovery again and flash it to magisk 23.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] xpil:
Sorry I wanted to say Nikgapps
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] MachineMasher:
You're right - I did flash LineageOS and then OpenGApps without rebooting in between.

Thanks very much for the suggestion. It may very well be that that will fix the issue, but I stressed myself out yesterday too much when I felt on the verge of bricking my tablet, and I don't think I am ready to do that to myself again just yet. Maybe I'll try it again at some point, but not right now. :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] xpil:
I asked and the havocos forum regarding viper4android. Has anybody successfully installed it with this ROM? I have installed it in my t825 but it doesn't seem to change the speakers sound at all. I tried changing all the parameters with no success.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] tripl3b:
Do I need an SD card to install or will it work with internal memory? My SD card slot doesnt work…
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
You can install a custom ROM using ADB sideload in TWRP. SD card is not necessary.

Turn on the ADB sideload mode in TWRP then enter `adb sideload rom_name.zip` command to flash.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] LedgendaryEpics:
my s pen works but i dont think the button does on this rom. Also, im the current build, virtually all browsers except firefox crashes and stalls so any fix to that or suggestions would be greatly appreciated.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
On my T825 Privacy browser and Vivaldi are the only ones I use and I have no probs with them.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] LedgendaryEpics:
yeah but brave, chrome, kiwi, opera, lite browser, etc are crashing, have jittered scrolling which affects the whole system after a period of time, only other browser i used is firofox/fennec, just need to know if im the only one and/or if there is a fix for it.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
@LedgendaryEpics just to please you I've installed brave.

Usage for 10' resulted in no probs.

Animations in settings turned off same in Nova Prime launcher.

Samsung and built-in browser no probs either.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
With my settings Brave Browser works without any problems.

Understood now?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] LedgendaryEpics:
the problems i listed was after I flashed the rom, i just need to know if it can be fixed
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] xpil:
First of all I would like to thank Awesometic for the excellent ROM. I have been using this ROM from the first day it was uploaded without any crashes. Everything works perfectly and I managed to pass safetynet test so my t825 is certified under magisk 23.

As a long term review now, I have to issues to report:

1) Every time I use OTG (with a flash drive) my WIFI does NOT function correctly, or does not function at all.

2) Quad speakers function all the time but it is my impression that the power coming out of them is less than 50% the original power, i.e. the power when the original ROM was installed.

Has anybody noticed similar issues, and if yes, does anybody know how to fixe them??
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] gareth16:
I would also like to thank Awesometic

Fantastic rom , I too am having the volume issue how do we go about boosting it , is there some way a non dev like my self could assist?

Thank you for the fantastic rom
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Was just about to test it but the stick wasn't correctly recognised.

Although just tested as usable in another device.

When trying to copy something onto it from the NAS using Total-Commander it just showed what's in the pic.

Properties rwx were the same as SD (770).

Format vFat might be the cause I thought so sitched to TWRP and formated as ext4.

Reboot - > system says problem with the stick (do I want to format?) so I did - > vFat.

Gave up but no WI-FI probs meanwhile.

Just another info: battery usage in deep-sleep (fmight-mode) turned on is brilliant ~0.1%/h.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] xpil:
I found the following in the internet to overcome the OTG problem and be able to use a stick right away. NOTE THOUGH that after this I had the problems with the WIFI that I mentioned in my previous message, only when having the stick plugged though, but I got used to it.... either WIFI or OTG....

So the procedure is the following:

use a terminal emulator and type su to become superuser ( you must be rooted to do this and I am via magisk).

While you are superuser type the command: sm set-force-adoptable true

Then press enter

That's it
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
@xpil thanks for the info.

As I use OTG perhaps twice a year I will not test this cmd.

Prefering trouble-free WiFi.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] xpil:
Sorry if I mislead you. If you used the approach I have mentioned, then wifi works perfectly as long as you do not use otg at the same time. So, in your case you will have problems with wifi ONLY the two times per year you use the OTG. The rest of the year WiFi will be trouble free.....
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Thanks.

Perhaps I misunderstood you.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Ruudvan10101:
Thank you so much

My tablet t820 was restarting randomly and now after flashing it's stable and so fast

I flashed without any gapps

I just have one problem that when I make a hotspot from my mobile the tablet connect but always giving me no internet

Is there a fix? Should I flash gapps?

Thank again

Edit 1: I flashed micro gapps => got stuck at boot animation

*fixed* Edit 2: wiped system cash data and then reflashed just the LineagesOS and then the wifi connected and was all good

Edit 3: the tablet speakers volume is low ... Airbuds and Bluetooth speakers are fine

*fixed* Edit 4: I noticed that I get so much better volume if I turned off the Audio FX

Edit 5: the tablet reboot whenever I use something that had to do with google play services
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sebvalmont:
After updating to 2021. 12. 19 I am having two problems:

1) my battery consumption is considerably higher.

2) i have to wipe dalvik cache everytime I want to use HBO Max

In addition, the camera is green/blue on Zoom. But it was happening since the previous versions.

I forgot to say that I wiped everything (including data) prior to installation and I flashed Gapps Nano.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Can't confirm that for T825.

As said before battery usage in deep-sleep (flight-mode turned on) is brilliant ~0.1%/h.

Using BitGapps ARM64.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sebvalmont:
My unit is T825.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:

[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] mich3lam:
I cannot thank you enough for this... I have been losing patience with this tablet and haven't been using it because it was getting slow and now it's all smooth and working again, thank you!

wanted to ask regarding the camera, I've read the first post and from what I understand it was recently fixed and the camera app is fine but is very weird on Zoom, also seen it's known issue, any idea for workaround?

Thank you again!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] LedgendaryEpics:
There used to be a gcam variant that worked for this device, I'll look into it
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] franzli:
Finally got around to trying this a week or two ago and I'm really impressed - Wifi Display seems to work stable, which is great!

Only thing I noticed concerning WiFi Display is that an app like Squid, which I use for presentations, doesn't seem to be able to use presenter mode, where the projected display just shows the drawing canvas (or pdf for that matter) without the drawing tools and Android status bar etc.

It shows the extra button in the UI showing that detects the possibility for screen share, but it remains on the default 1:1 screen share. On the Stock ROM this function worked, but it may also just be a general restriction of LOS. I think it should work well enough as it is, just mentioning this in case an easy fix comes to mind.

The only other drawback I found was that I couldn't get Netflix to run. Tried with Magisk (both an older version that still had Magisk Hide and the newer versions with zygote) and various types of Netflix apks and all of them give me this "couldn't connect to Netflix" error (sometimes with different error codes depending on the app version). If anyone's can share the steps for a workable setup that would be great! (Amazon Prime app is running fine by the way, but they probably check in different ways.)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Hello all.

I really appreciate you all for having interesting in this LineageOS and HavocOS.

And I'm sorry for the late reply these days.

I couldn't actively maintain it because I have been having busy days recently.

I know there are lots of major issues, as you all gave me feedback thankfully,

But I'd like to solve some things first.

Hopefully, what I'd like to resolve are

1. Merging AOSP kernel patches: This may resolve some unstable behavior

2. LineageOS 19: I can build LOS 19 image but it doesn't run at all. Maybe it needs some more patches from the LineageOS team.

While I'm working on these jobs I might solve some known issues too if lucky.

I'm watching this thread (the HavocOS thread too of course), and reading all your comments.

Thank you for the encouraging words and feedback.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
If anybody is thinking of testing Havoc I switched today and these are my findings.

To put it short : extremely easy to switch to Havoc as LOS Data can be restored if not even flashing dirty is possible.

THX @Awesometic
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] roesja:
Still using this rom as my daily driver! Excellent performance and battery usage! Thanks again!

At the moment I have encountered two issues:

1. The samsung keyboard cover seems to have the arrow keys rotated; not sure how to solve this

2. Fingerprint reader doesn't work in 3rd party apps (Like keepass2android); (Biometric hardware not detected)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Hello all.

I uploaded the new versions for LineageOS 18.1 and HavocOS 4.13.

Those two versions are synced with the latest Android sources respectively, and it comes with the Android security patch by Jan. 5, 2022.

I found another latest firmware of our Galaxy Tab S3 in Brazil variant. This is called T825UBU3CUF1, and it was released in July 2021. Unfortunately, this hasn't a driver update in Adreno and some other things but seems like it has some fixes for the bugs it has before. I applied the new blobs to my ROMs and on my side, it works just fine and there is no new bug for me.

This firmware is for T825 but my co-workers in the Telegram room confirmed it also works on T820. Thanks all for the test. :)

And I fixed the fingerprint working on a third-party app. I tested this feature with AppLocker from Playstore.

Also, I tuned a property value for the schedutil governor that is currently we are using. It reduces reactivity theoretically, but it is still smooth and usable.

For my usage, if you are using a Kernel Adiutor app then I recommend down-clock the big core to 2 GHz.

This presents us better battery and thermal but brings no bothering lag as before.

Enjoy, and sorry for not solving the other issues yet. :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] castoruser:
Hello @Awesometic ;

thanks for your great work on this tablet.

I tried to build myself and got always this error with the kernel by round about 41%:

Do you know what is the Problem?

I tried to find myself, but I didn`t find anything.

thanks for your support.

greets Castoruser
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] franzli:
Hi, I haven't tried building this myself yet, but did you check whether you have a programme called ld installed? According to the error message that seems to be missing.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] castoruser:
What is ld? I've searched and nothing found...

I have build in the past other builds e.g. castor or n1awifi no errors
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
There are several ways to fix that problem. My choice is to create a symlink for that lld file to trick the compiler.

Please refer to this patch: https://github.com/awesometic/andro...mmit/780bb8553ce2ab051bc721186fcb4a29809a8d38

Hi @Awesometic,

thank you very much for your work!! Great ROM!

I would love using it. But device encryption is really important to me. Do you see a way to activate it? Do you have an idea what's wrong?

I played a little bit with the fstab file. But up to now all changes ended with a boot loop. I thought that only the function to encrypt the device afterwards is broken. So I tried to enable encryption on first boot...
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Hello,

Sorry, in fact, the hardware encryption feature is not a priority thing for the current state.

So currently I don't know which part is wrong and which thing I have to do to fix the HW encryption feature.

Before fixing HW encryption, there are other major things like stability, hotspot, USB OTG, SELinux, and Android 12. 😅
