[ROM][UNOFFICIAL][11][EAS][SM-T820][SM-T825][2022-05-08] LineageOS 18.1 for Galaxy Tab S3

[xpil]

@xpil thanks for the info.
As I use OTG perhaps twice a year I will not test this cmd.
Prefering trouble-free WiFi.

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.....

Perhaps I misunderstood you.

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

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.

... 1) my battery consumption is considerably higher.........

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.

My unit is T825.

@sebvalmont forgot to say that I'm using Kernel Adiutor reducing big and little max frequency each one step lower.

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!

There used to be a gcam variant that worked for this device, I'll look into it

Hello.

I uploaded the new LineageOS 18.1 release with lots of improvements.

Now we're using the EAS kernel, so I changed the default CPU governor to schedutil.
And I fixed flip cover working, and fixed aptX/aptX HD codec on Bluetooth media playback, and also fixed WiFi display.

But there may be some existing issues still remain like the camera preview issue on Zoom app, supporting the PS4 controller, and so on.

Enjoy, and let me know if there's an issue.

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.)

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.

 

[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

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)

 

[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.

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%:

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.

 

[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

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

 

[castoruser]

I copied the two files inside the Folder......executed, but the same error....I have to check this later
