Probably the fact that it's a custom ROM.

Read in other threads that Netflix doesn't like that.

Same with some banking apps and more.

Download it from ApkMirror or similar site and ALLOW when it asks to when it asks for permission to install.

@Awesometic can you please solve the problem:

Two independent users of your ROM have noticed that the same MAC address MAC: 00-a0-c6-eb-5c-d8 is always displayed on five different Galaxy Tab S3 (SM-T820 + SM-T825).
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ronnz98:
I can confirm this. On my Galaxy Tab S3 (SM-T820 + SM-T825) both have MAC: 00-a0-c6-eb-5c-d8
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Bertybassett99:
couple of issues. If i click on the settings icon in the drop down menu, the screen blanks and the settings do not appear. i have to click on the settings icon.

And secondly wifi drops out after a while.. Speedtest reports the wifi is unstable.

Wifi works fine on other devices in the house. THe wifi issue is a pain in the arse

The other day I did a Zoom meeting and the camera didn't work at all (not talking about the green bar issue; the camera wasn't working at all).

I tried a few other apps as well and none of them are detecting the camera at all any more.

Can someone else who is using the 2023.11.15 update confirm that the camera is still working for you so that I know that the issue is on my end and not with the ROM?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] kubelas:
I rarely write anywhere in internet but would like to Thank you personally for shrinking hope regarding our beloved S3.... Thanks a lot mate and wish U all the best from me as much as from anonymous thousands of users who can now pick it up from the drawer and use it as it supposed to be from the start. Namaste Bro!🙌🙌🙌
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] cherepanov:
Great work!

Just flashed on SM-T825:

twrp-3.5.2_9-0-gts3llte

lineage-18.1-20210703-UNOFFICIAL-gts3llte

magisk-21.2

open_gapps-arm64-11.0-nano-20210513-TEST

Discovered so far:

initial setup is buggy, unable to import settings from cloud

S-Pen works

LTE works

don't work with BitGapps R28

Permanent notification: "Serial console enabled. Performance is impacted..." - never face this before

chrome is crashing on video playback
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] marcosmjpa:
Is the Opencamera working?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] cherepanov:
No. Camera not working, probably because of missing hardware config
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sebmue:
What great news! Just took my T820 out again just to realize again it is barely usable these days and makes nothing out of the Snapdragon 820.

Thank you for taking the effort and bringing a modern rom to this still unique (screen ratio!) SPen device. Was just wondering wether I finally give up and buy an iPad Pro (screen ratio...) 😅

Just bought you a coffee. Thanks for your support :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Thanks for the test results.

So the bugs you could find are,

- SD card no longer recognized after clean install from the image file of the SD card

- Playstore doesn't show the apps that already bought before

- Vivaldi browser is laggy and freezes quite often

I will add them to the to-do list. In fact, with the SD card and the Playstore thing, I couldn't face the same issue as you. :unsure: But anyway, those are now known issues.

I think I set the essential partitions as much as possible, even if all of them are not needed actually. And the date and time problem, I believe that it is not related to the partitions. Maybe data partition? But it is one of the really necessary parts. So I'm sorry, I couldn't face the same issue and don't know how to fix that date/time issue.

You can try formatting cache partitions using TWRP or flashing the ROM after erasing all of the partitions, e.g, system, cache, data, internal storage.

Yeah, I just needed to make sure, I'd say, for troubleshooting. :)

I want to use this tablet as a daily media player if I can. It has good speakers and a good display.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Many thanks and I glad it could help people who want to use this tablet again. :D

Thanks for the reports,

Come to think of it I didn't try the import settings from the cloud. Well, need to find out why.

That serial console message could be disabled later, I got some information about them but have not tried yet.

By the way, I really need to try out the BitGapps and Chrome. Those are the most noticeable common issues from the feedbacks. :unsure:

IMHO, I don't believe the ROM settings or the kernel affect the Chrome working but I have to see the logcat.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Thank you for the coffee. :D

True, this is the last flagship tablet that has a 4:3 screen ratio comes with supporting the stylus. It should not be abandoned.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sebmue:
Ok, some more impressions after some hours of use on a T820:

Much faster then even tweaked stock. Great.

Network works fine.

Sound works, no further testing

SPen is a mixed bag. It works, even with some palm rejection, but not constantly. Writing in OneNote or other apps does not work reliably with the palm on the screen. I know that this isnt a specific problem of this rom, but a Lineage thing. Front what I know there is a fix around - if I manage to provide more information, are you willing to implement it into the kernel/rom?

Thx so far!

Edit: this seems to be a quite easy SPen fix for someone already compiling :)

https://xdaforums.com/t/fix-enable-palm-rejection-for-spen-on-non-stock-roms.4042799/
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Thanks for the information.

The palm rejection, I think it is a really needed one with no doubts. I will look into this and this will be a quite high priority.

Because S-Pen is the key feature of our tablet along with the quad-speakers and the display.

Please understand, I cannot sure whether it will be implemented or not because I don't know how difficult it will be. 😅

But will give it a try.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sebmue:
Thank you for trying. I will try to help with possible hints and resources from the web where I can. It does never mean I expect you to do anything. I really appreciate you effort and the current state already makes it worth to at least create one mostly stable and working release IMHO. Good luck!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Stogie87:
Hi there.

Is there any chance, that we can get palm rejection into this rom? (That the device does not recognize your hand on the screen during writing with the spen)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sebmue:
Read the three posts before your question. In short: a chance there is :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] marcosmjpa:
Thank you very much for your effort!

I love this tablet. It is light, has an amoled screen, LTE and SPen and replaces a cell phone with advantages.

Its processor and memory is enough to run for a few more years if it weren't for SAMSUNG's policy not to optimize its older devices.

I will definitely buy you a coffee as soon as the last item important to me is working, which is the camera.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
It'd be great. I always say that the camera will be the last part to be fixed, but now I'm getting wanted to fix the camera a little bit. 😂

I can't say that it is for the coffee, but it is also true that fixing the quad-speakers is so difficult on this device.

A little bit more to say, I used a decompile tool to see how the SoundBooster libraries are called but it is really spaghetti-ed as expected.

After some more tries on the other parts including Palm rejection, I will look into the camera too.

By the way, I didn't expect that many people want its camera. 🤭
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Stogie87:
Actually palm rejection and speaker are the most important features of this device. We never had a custom rom with these features working, why i always had to stay on stock rom.

Thanks for your efforts. I hope you will made it. :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
By the link attached in the quoted post, I could implement the Palm rejection for S-Pen.

I have tested with the Sketchbook app, and there's no issue like canceling drawing when I touch the screen during drawing something with S-Pen.

Anyone who uses S-Pen on my LOS, please test the newly uploaded ROM, which is 210714, then let me know the results.

Thank you @sebmue for the informative thread. As you said, it wasn't that difficult to edit the sources because the basic structure is almost the same. :D

The things I found during the implementation;

- I got the hints from him so tried to edit other parts rather than Android frameworks but just realized that it seems like his method is the simplest and the most effective. 😅

- And it seems like the AOSP already has an implementation for rejecting the touch event while the stylus draws something. But it looks like it only works when the app has some proper permissions to make Android's Inputflinger accesses the app. So, if it is correct, I think this part makes the palm rejection looks like working but only sometimes.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sr.arenisca:
Wow, I just dusted this old tablet and I'm super pleased to find a "recent" ROM that is developed. Thank you for your work. Is there maybe a telegram channel for discussing ?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Good idea. I have made a group chat in Telegram and share its link to the original thread. Please check that. :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] sebmue:
Mate, this is great! Awesome result, tried it in Onenote and it works like it should. Thank you so much!

I would love to check out some Kernel tweaks - LOS makes the device much faster than stock, but I have the feeling it is much slower than it should be with the SOC and 4 gigs of RAM.

The One Plus 3 has a SD 820 as well and I guess it could provide some short paths for implementing OC etc. - what do you think?
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] peterl30:
Hi,

I have already installed Lineage OS 18.1 but with a built from 2022. Now I have a few questions:

Is it possible to upgrade by dirty flashing this image here via TRP? (SM-T820)

Or do I have to falsh with Odin or ADB (which will result in all my DATA gone?)

regards
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Probably nobody will give you a guarantee that it will work even if it would.

Of course you can make a backup via TWRP first, try dirty flashing and if it doesn't work you can restore the backup.

BUT I've tried that in the past (different device/OS) and restoring didn't work.

So 🤷‍♂️

No as TWRP is already installed and that's all you need to flash LOS.

@Awesometic Thanks again.

Made another fully clean install.

This time TWRP keeps recognising USB-OTG and my SD card every time I booted to recovery, but LOS doesn't like either of them.

Freshly put in SD gets formated to vFat while the one I tried it with is on exFat.

ROM is very snappy. Great experience.

Vivaldi Browser freezes again while LOS browser and Firefox have no probs.

Wifi made it only once to connect to WPA2+3.

After changing router to WPA+2 T825 always connects.

LTE works but I tested it only for a few minutes.

Will fully set it up and carry on testing then write again.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Glad it works. :)

The kernel tweaks, actually I have been thinking of that too.

I'm willing to tweak the kernel but I think this is not the time because there're so many things to be fixed yet.. 😅

Will look into the kernel, along with the LOS's OnePlus 3 kernel source.

If you have some idea or find something that looked like we can use it easily, let me know that then I will work for it.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Thanks for the review again.

Yes, it looks like something to do with the file system.

Weird thing is that the current kernel and the init scripts are all from the stock.

So maybe the problem is in the LineageOS parts.. Needs tweak.

By the short search, I found a patch for the WPA3 problem. Is the stock ROM also not support WPA3? If so, we can disable the WPA3 mode to prevent the problem. :unsure:
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] marcosmjpa:
I need the camera because I use this tablet as a cell phone and for work. For me it's perfect because of the size and 4:3 aspect ratio.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] LedgendaryEpics:
Is there a way you can modify the kernel to

Going on kernal tweaks, the last dev for 17.1 failed to enable the option to have on-screen soft navigation keys, and was wondering if in the future this could be enabled? Itd make this rom 10x better with that alone for me.

Also some bugs-

Charging and discharging while typing or tapping jitters the screen

Bluetooth doesnt seem to work for t820

Browsers and keyboard while snappy tends to freeze, apps in general freeze some more than others, but browsers are having a touch time with this rom

Battery life in the first build was beyond unbearable, but got exponentially better with the recent july 14th release but still has a way to go.

On reboots or restarts, lockscreen makes you unlock twice... Dont know if thats a setting i can disable or not.

Advanced restarts (recovery) work 50/50, sometimes it works for boots to twrp, and sometimes it hangs

These are the bugs and suggestions Ive found so far. Great rom keep it up
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
In the meantime:

Found out that the exFat SD card which is rejected by your LOS gets directly accepted on my T325 with as well LOS18.1 but kernel 3.4.113.

Another vFAT formatted SD card got accepted by your TWRP+LOS also.

I will give ext4 a try as well.

Another thing is that charging while turned off leeds to button combo being necessary to restart it.

WPA3 I've turned off in the router.

Vivaldi is a no-go as I said.

Netguard working fine.

Audio jack gets no signal.

ext4 wasn't recognized.

After around 1h surfing suddenly it went into bootlooping.

Took me some time to find a button combo to stop that.

Then I rebooted to TWRP, wiped Dalvik+cache, then it started normally again.

Could pull logs in TWRP but I guess they're useless.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
@Awesometic For checking the Vivaldi freeze I've installed its base=Chrome which freezes as well.

Edge chrashing as well. Same base also?

I wonder which logs would help.

Really appreciate your work.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Yeah if you can catch it, I need the logcat dump while the error occurs.

Because I need some clues for debugging the bugs, I couldn't reproduce all of them on my side. 😅

Some of the critical bugs may be from the un-completed device tree, which means while there are HALs for some components but those components not working actually, such as DRM, WFD, ...

Or, maybe from the unreliable kernel. Our kernel is based on the Pie, it has the patches from the mainline but the official support also ended in 2019.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
I think I did fix DRM :D

Yeah, it enables L1 widevine. I can play HDR, HD videos on Netflix, even though the apk file has to be downloaded from the Internet.

And fixing DRM may also fix the web-browser freezing issue. I got a logcat thanks to @bmwdroid, and I found the DRM-related messages on the log. Don't know, but for me, during about 10 mins web surfing using Vivaldi it has no lag, no freeze, and can play Youtube videos. but I still need you guys' help for confirming.

Please wait for the next release for a while. :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
@Awesometic fyi just noticed that battery usage is not displayed.

T825 tells me it has been fully loaded 34h ago and screen has been used for 1h23'.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] marcosmjpa:
I'm in the greatest anxiety for the camera problem to be solved!
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Dwightsch:
Hi again thank you very much for your timely response and sorry for mine being late.

I see that you've already implemented it. there was a post here on xda which mentioned that it was included in LOS source and since some commit they removed it. I tried to add it to the LOS 17 kernel here but it didn't function correctly.

My beef with the official rom is that GMS uses ridiculous amounts of resources, and there's a weird issue when you add Magisk, the SE audits freak out. the device has a relatively good display and speakers but all the rest is crap. the background usage issues are major and causes the device to overheat which causes it to throttle aggressively.

anyways one other thing I wanna mention is that I tried to compile the official kernel with the Force SE linux thing and some other Security flags disabled so I could change stuff up both in cpu freqs and governer and GMS and ... But for some reason it boot loops, I used the Anykernel thing to flash via twrp and with some effort I booted up and everything was broken, wifi lte and ...

anyways this is the most frustrating thing I've ever owned and I cant replace it :)

LMK if there's any testing, logs and etc you need. I have a t825 international
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Thanks for the report. There are still no changes after a few days?

Yeah. Now I think I should start fixing its camera.. I have tried a lot of work for fixing quad-speakers but so far no good. I can use the minimal amounts of vendor files for loading vendor audio HAL but it annoys me about the invalid sound card. But I don't know how to notify the specific sound card for the HAL. o_O Or, maybe recognizing a sound card isn't a culprit.. Don't know anyway.

It'd be really great if you tweak the kernel. And I know one more developer who is in its kernel development. I created a development channel on Telegram, if you are willing to join us please PM me. :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
After fixing DRM, I have tried fixing quad-speakers but I got stuck and have no idea how to fix it for now. So.. I think fixing quad-speakers should be the later job.

So, now I will try to fix the camera from now on, and as always I cannot say it will be fixed on the fly. Just will do my best but there's no guarantee. 😅

I will upload the new release within this week. The release will contain fixed DRM, fixed Bluetooth on WiFi variants, and so on.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Sorry, no usage noted.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
Okay, I will look into that issue. :)

Thanks for the test.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
For me it's not really necessary that you put work into that.

Just noticed by accident anyhow.

Shouldn't be relevant for the apps I use as I've never noticed anything special on none of my 7 devices I use regularly.

Please tell me if you want me to test anything else.
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] Awesometic:
I just have uploaded the new releases and updated the thread contents, changelogs, and the post about quad-speakers.

This new release has DRM supports come with Widevine L1, but also has a huge improvement on the audio side.

Please check the original post of this thread. :)
[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] bmwdroid:
Thx a lot. You're great.

Just made a dirty installation wiping only System+caches.

Bottom speakers 👌. I love it.

Vivaldi browser seems not to freeze any longer.

Battery usage displayed I'll check when fully loaded.

Will test more.

Edit: forgot to write that obviously I had to flash Bitgapps64+Magisk as well.

Battery usage still only shows display time but no apps and I don't care.

Vivaldi had no crashes at all (no other app either).

My daily driver on it.

Wi-Fi, LTE, BT connections stay strong.

GPS locking (sensors only) very fast.

Brilliant work @Awesometic.

Just hoping for camera now as I can live easily with only two speakers working.

App usage of battery not being displayed, I don't care.
