Hi, awesome build, great to have an updated for my T710 :) But...I have a problem with the fingerprint reader. I can register fine, and if I lock then immediately unlock it works, but if table is locked for more than about 10 seconds, fingerprint reader is no longer active.

I have run clean install twice, once about a month ago, and then again today.
[Galaxy Tab S2 Android Development] lpedia:
This has been a problem for quite a few generations of the OS. It seems that touching the reader doesn't activate the fp code after the device has gone into sleep mode. See, for example, https://xdaforums.com/t/rom-9-0-0_r...ded-rom-v6-7-unofficial.3979381/post-80607241.

It's unlikely to be fixed, because the fp code is proprietary and the source isn't public (and it won't be updated by Samsung).

Preventing the device from sleeping does keep the fp reader working, but at the expense of battery running time. :(
[Galaxy Tab S2 Android Development] bmwdroid:
fyi never tried to acitvate as I always thought fp doesn't work at all.

Today with latest build for T810 I registered 2 fingers to test.

Unlocking doesn't work at all and Keepass says no fp hardware found.

Don't need that feature anyhow.

Hi @ripee , I've just installed the latest 23/11 build for SM-T715:

- The Wi-Fi problem of the previous builds is solved, and now it's back to normal,

- The "back" and "multiwindow" buttons issues still persists

Other than that, build that working like a charm!
[Galaxy Tab S2 Android Development] ripee:
I have not been aware nor do I have any idea how to fix the back and multiwindow buttons. Are you not able to set their functions in the settings?

More importantly, does the mobile connection work?
[Galaxy Tab S2 Android Development] UbaldoColdagelli:
I'm not using mobile connection on my SM-T715 (I'm using it on an Iphone 8), so in this case I'm not able to give a feedback...

For the "back and multiwindow" issue I never touched the functions in Settings (that are the "default")...
[Galaxy Tab S2 Android Development] ripee:
So please go to the System section of the setting menu, then Buttons, and see if you can make any changes to the button settings that you wish to make. This works on my T810.

I have also made some changes to RIL on the LTE variants that are a bit different than what retiredtab made a few months ago. From what I can tell, I made all the necessary changes that other similar exynos sources have made to get RIL working on 18.1.
[Galaxy Tab S2 Android Development] UbaldoColdagelli:
1) I can make changes to the button settings. But the buttons are both not working, even with the changes made.

2) That's very strange for the RIL aspect on my SM-T715.

PS: I've just send a message from me on your Telegram...
[Galaxy Tab S2 Android Development] aj97:
Ah, no problem, thought it was just me as I didn't see it in the know issues and couldn't find a definitive answer in this thread (maybe need to search better!) Thanks,
[Galaxy Tab S2 Android Development] metterschling:
Hi, from which prior build did you get to the 18.1 build? Through (re)-stock or full wipe including data/sdcard wipe?

On my (encrypted) SM-T715 that is running the January 16.1 build, I am not able to boot any 17.1 or 18.1 build.

Today I did a nandroid backup, then factory reset and system wipe, then installed the 23/11 18.1 build. After boot to system, I can enter the encryption password, but then the tablet is stuck in boot animation. I waited at least 20 minutes before cancelling, then restored my 16.1 nandroid backup for now.

Do I need to format sdcard/remove encryption or is there anything else I'm missing? Any hint would be very appreciated!
[Galaxy Tab S2 Android Development] halloarno:
Hi, I am verry happy with the 18 Lineage builds for my smT810.

On the last two builds (23/11 and 27/11) I experience WiFi dropouts (a few minutes it's OK, then lose connection). If I recall correct on build 3/11 it was OK.

Any one else too? If not I will do a fresh install (not a dirty one).
[Galaxy Tab S2 Android Development] bmwdroid:
@halloarno fyi mine is still on 20211120 and has no wifi drops.

My router is on 2.4GHz only.

Didn't try the later ones but this version I've installed by only wiping system first.
[Galaxy Tab S2 Android Development] dcaffeine8d:
Just installed the lineage-18.1-20211127-UNOFFICIAL-gts210wifi.zip 2 days ago on my T810 and everything is working well. I was on AOSP v6.3 for almost a year but this A11 version seems to be stable. No issues yet. Battery doesn't drain. It was a fresh install and just restored all my apps using migrate-ng .
[Galaxy Tab S2 Android Development] halloarno:
Solved by wiping all settings for WiFi/bt/etc in settings/system menu. Totally not rom related.
[Galaxy Tab S2 Android Development] kebe:
Hi! Recently I dusted my T710 and flashed lineage-18.1-20211127. What can I see most of the things works fine. However i noted that after reboot WiFi from time to time isn't able to establish connection without toggling it. I'm talking about fresh install with full wipe etc.

Today also weird thing had happened. I've put tablet at my desk running YouTube then I locked screen.

In the morning tablet was in recovery mode saying that is not able to load system. I rebooted it and everything works fine.

However i have a question - does this build come with videwine blobs? What I read is AOSP including LineageOS should contains it by default. When I use app or check for DRM info everything freeze with loading spinner.

Second minor issue is that apps are not aware of fingerprint sensor. I wonder if it's related to some global system API's or app implementation?

Lastly i have problem with running chromium based browsers without freezing. I read that it's a global issue with LineageOS but it may be related to HW architecture?

Overall - great job of bringing to that devices fresh feel of LineageOS :) 🍻
[Galaxy Tab S2 Android Development] djcasl:
I tried a clean install on SM-T710 hangs on bootscreen. Eventually stops and goes back to TWRP. So can't use the latest build.

Update: Downloading new files via PC and will update TWRP to 3.6, will let you know the outcome.

I got a install screen from Android. I found the problem it was the GApps Package, I used an older version I saved from a previous install. So the GApps Nano and Micro packages from december 02 and 03 won't work for me with the latest image. Should the GApps package be older then the build?
[Galaxy Tab S2 Android Development] djcasl:
@kebe I saw you did a fresh install on T710 as well with the 20211127 image, how long did first boot take for you? I am currently at 15-20 minutes and still at the boot screen.

Nevermind, I found the problem. See update above.
[Galaxy Tab S2 Android Development] kebe:
It was instant ~ 5min max.
[Galaxy Tab S2 Android Development] djcasl:
Chrome browser hangs all the time and Netflix and Disney+ won't start properly. Can't even log in. I am going back to a previous build.

Update: I installed de 1119 build, it's restoring my apps, I installed Netflix and Disney+ from APK, both work.

I used nano gapps from 25112012 since that seemed to be a very populair one. That one works with this build.

This image still has the problem, when you power off and plug in a charger, you don't get a charging animation, but your tablet just boots.

Update2, WiFi is dropping in thuis build 1114 didn't have that issue.
[Galaxy Tab S2 Android Development] d4ri88:
same problem. T815 with clean install and latest built. GPS not working and Chrome hangs and stop working.
[Galaxy Tab S2 Android Development] pflyaz:
Firstly, a huge thank you to ripee for the work here. I have both a T710 and a T810, and being able to run latest Android software on both those devices is a very nice capability.

I have been following all the rules on Page 1 of this post - clean installs using TWRP each time, Pico Gapps and Magisk.

I can report the following:

1. the 20211123 builds are the most stable for both T710 and T810. All browsers and streaming functions seem to be working fine.

2. the 20211127 build for the T710 and the 20211130 and 20211202 builds for the T810 all exhibit the same bug(s). They install and run just fine, but streaming apps such as Peacock, Plex, Cox, and iPlayer don't work. They just hang at their logo/first screen.

3. to install Peacock, Disney+, and Netflix, one needs to clear out all storage from Play Store and Play Serivces after having set up Magisk. And then reboot the tablet. After the reboot, those Apps re-appear in Google Play and can then be installed. Sometimes it needs two reboots, but it does work. I found this at "Netflix for rooted?" on XDA.

4. TWRP 3.6.0_9-0 is working fine for me. (Thanks again ripee!)

5. I have not tried the 20211203 build yet. Since I have a pretty solid setup with 20211123 I will wait until I see some success reports on this post before upgrading again.

6. I have seen some WiFi instability on the 20211123 builds on both devices, but it's very intermittent. The symptom is the WiFi drops and just shows "Saved" for the connection that was previously working. Tapping the connection does nothing - it's as though the WiFI subsystem has frozen. Turning off WiFI and then turning it on again in Settings sometimes fixes the glitch; but otherwise a reboot is needed. However, yesterday and today with a strong signal in my study I was able to watch NFL on Fox on Plex and several hours of rugby on Peacock with zero problems on the T810, and the T810 is still working just fine with no WiFi or other glitches.

Hopefully this info helps both the developers and more casual end-users like myself.

Thanks again Ripee!
[Galaxy Tab S2 Android Development] djcasl:
@pflyaz I just install the APKs from APKmirror or other sites for Netflix and Disney+ this works on the 1119 build. Have't tried the 23 build yet. But if WiFi is the same there is no need for me.

Thank you for the huge info update and testing.

Ripee thank you for keeping our devices alive. Keep up the great work.
[Galaxy Tab S2 Android Development] kebe:
As I said before streaming issue seems to be DRM related. I have an issue with ebook software as well. I will try 27th build and newer GApps since it migth be a Google Services issue.

My WiFi setup include both 2,4Ghz and 5Ghz bands for same SSID. I'm wondering if that's the issue. I think i had no trouble with WiFi from my phone hotspot (only 5Ghz) so far. However the behaviour is the same as @pflyaz stated (with one difference - i just had to wait for some time and toggle it to get it work without need to reboot).
[Galaxy Tab S2 Android Development] Das-Phantom:
I also have the WiFi issue (last two builds/ 12/3). T-810
[Galaxy Tab S2 Android Development] abde1983114LILAH:
Thank you very much for this great work.

Please I have two issues with lineage os 18.1, I can't find camera. Also Google Chrome keep crushing. For information I installed gapps stock version

There is anyone face the same problem? Thank you
[Galaxy Tab S2 Android Development] bmwdroid:
Can find camera but broken.

Open camera doesn't work either.

Not using chrome. My browsers are working fine.
[Galaxy Tab S2 Android Development] djcasl:
SM-T710 test with the lineage-18.1-20211203-UNOFFICIAL-gts28wifi.zip build

I Installed this with open_gapps-arm-11.0-nano-20211201.zip via TWRP 3.6.0_9-0

Did a clean install as recommended.

In this build Disney+ and Netflix work when I install them from an APK, I haven't used the trick to get it form the playstore, this works for me so I just use this.

Chrome works, not the crashing I had on the 20211127 build, please note, I don't know if this is a build problem or a problem with certain Open Gapps packages. The folder for december 02 and 03 have been removed from their site so maybe they had issues.

Starting from the 1119 build I have a WiFi problem again, from what I am testing is I can connect fine and then it keeps working, however when I go near another one of my MESH points it won't reconnect until I toggle WiFi Off and On. This was solved in previous builds, now this bug has returned for me.

And finally, the charging animation when the device is off is still missing, so connecting a cable will boot the system.
[Galaxy Tab S2 Android Development] proscons7:
I have SM-T815N0 (gts210ltexx 1203) which shows no sim card detected.

Is there any hope to fix this?

Thanks for all your efforts.
[Galaxy Tab S2 Android Development] bmwdroid:
Have to correct myself.

After a todays reboot camera is suddenly working.
[Galaxy Tab S2 Android Development] draxcreative:
I am having the same problem with WIFI on my T-710. Can you please tell me where I can download image older than 1119.

Thanks
[Galaxy Tab S2 Android Development] djcasl:
The cleanup the old builds, so that's not possible. I thought I saved the 1114 build on my SD, but accidentaly deleted that as well... :( Maybe someone still has it.
[Galaxy Tab S2 Android Development] draxcreative:
Is someone can give us 1114 that would be amazing
[Galaxy Tab S2 Android Development] pflyaz:
I am able to confirm the comments from @kebe and @djcasl regarding the WiFi anomaly. I am still running 21011123 on my T710 and my T810 per my Dec 3 post. I have an ASUS AiMesh between two AX88U routers at either end of my home, and when I switch from one to the other the glitch usually occurs. I have seen similar glitches when moving around at my work office and my church which both have enterprise-class mesh networks across campus. On the T710 I believe I have always been able to recover WiFi by switching off WiFi, counting to 10, and then switching it on again. On the T810 that has rarely worked, and a reboot is usually needed to reestablish a WiFi connection. I hope this additional info helps the developers identify the issue here. I would also be happy to downrev to 1114 if that has solid WiFi and streaming working.
[Galaxy Tab S2 Android Development] Sappron:
I wonder if someone from the team is thinking something about android 12. If they are doing something about it, then it sounds amazing and great
[Galaxy Tab S2 Android Development] haircut313:
I have the 1114 build file
[Galaxy Tab S2 Android Development] djcasl:
@haircut313 thnx your a life(tab) saver. Will try to re-install this weekend.
[Galaxy Tab S2 Android Development] djcasl:
I saw there was an 1208 build available, so I did a dirty install over my 1203 build. Netflix and Disney+ not starting. So that's a no for me. I used tha 1207 nano gapps package maybe that was the problem. That one is about 100 MB smaller then my previous one. Gapps shouldn't mess up DRM right?
[Galaxy Tab S2 Android Development] manhart:
I installed lineage-18.1-20211208-UNOFFICIAL-gts210wifi.zip yesterday evening on my T810. The WiFi problem is still a challenge. Sometimes i get WiFi running with flight mode off/on, but not always.
[Galaxy Tab S2 Android Development] djcasl:
So I started with a clean install from 1114 build and Gapps package nano20211112 so it's older then the build and let Google play update the rest.

First thing I notice that during install my WiFi allready stays stable. With the later builds, I sometimes need to reboot before I can reconnect to my WiFi.

I installed Disney+ and Netflix from APK they work. So Now I start walking with the tablet. It disconnects from one MESH AP and connects to another and I my WiFi is off for about 3 seconds and then it's reconnected. No toggle needed. No I am waiting for the 78 other apps to be reinstalled.

But I think I will stick to this build for a while.
[Galaxy Tab S2 Android Development] Kyrat:
Hi, I don't know if it's normal or not but always when I record my screen with system audio, it doesn't save audio by youtube (in my case I use vanced)
[Galaxy Tab S2 Android Development] gege0202:
hi, someone have a link to go back to v 17.1 for t815 please?

my sim don't work on v18

thanks
[Galaxy Tab S2 Android Development] d4ri88:
only sim dont work? on my t815 GPS doesnt work and battery drain while standby around 3-4%/hour with wifi, bluetooth turned off.
[Galaxy Tab S2 Android Development] Surfer_II:
here you go ...

I also turned back to ripee´s last 17.1 build on T815 by clean flash since the 18.1 builds still have some bugs (SIM not working, etc. - see d4ri88´s post above)
[Galaxy Tab S2 Android Development] gege0202:
thank you, same troubles
[Galaxy Tab S2 Android Development] helipus:
I do experience the same wlan connection issues on my SM-T810 with following version:

lineage-18.1-20211121-UNOFFICIAL-gts210wifi

I would like to try build 20211114 which worked for @djcasl . Has anyone this build still available? Its not at the download location anymore. Or is this issue solved in one of the actual dezember builds?
[Galaxy Tab S2 Android Development] helipus:
I just tried build lineage-18.1-20211208-UNOFFICIAL-gts210wifi. here the wifi is not working again.

So can please some provide me with the build:

lineage-18.1-20211114-UNOFFICIAL-gts210wifi
[Galaxy Tab S2 Android Development] ZeyphurX:
I'm new to lineage os, coming from rr rom. how do I turn on gesture navigation?
[Galaxy Tab S2 Android Development] ZeyphurX:
update, solved with termux app
[Galaxy Tab S2 Android Development] helipus:
@halloarno solution worked for build lineage-18.1-20211208-UNOFFICIAL-gts210wifi only for 1 hour. Then the wifi connection was lost again.
[Galaxy Tab S2 Android Development] d4ri88:
thanks for attached rom, its running much more stable than the actual 18.1
[Galaxy Tab S2 Android Development] Surfer_II:
With the latest build 18.1-20211208, my T810 shows better Wifi connection with 2,4 GHz and much less stable connection with 5 GHz. Sometimes the connection gets lost in longer sleep mode phases, but reconnects easier in 2,4 GHz Wifi.

After reconnecting to 2,4 Wifi a manual switch to 5GHz is possible. However, once loosing Wifi connection in 5GHz, it gets tricky or impossible to reconnect to Wifi at all. It takes some seconds and a few tries until the tablet reconnects as if a required "Wifi service" requires certain time to reactivate.

What I also note: after flashing a 18.1 build / wipe cache/dalvik in TWRP and rebooting, the Wifi connection does not work despite Wifi is on. Only after deactivating & re-activation of Wifi it connects (if you are lucky).

@ helepius: Maybe you also try 2,4 GHz Wifi and see if this works better for you as well.
[Galaxy Tab S2 Android Development] helipus:
@Surfer_II : I need 2,4GHz and 5 GHz activated at my router and don't want to have different SSIDs for them. Having this in mind is it possible to decided on my tablet which network to use?
[Galaxy Tab S2 Android Development] bmwdroid:
Imo no
[Galaxy Tab S2 Android Development] Surfer_II:
Had the same situation here and have changed the SSID of the 2,4 GHz Wifi to make it visible/choosable.

Otherwise the tablet will preferably autoconnect to the 5 GHz Wifi if the SSID is identical.
[Galaxy Tab S2 Android Development] pflyaz:
Firstly, thank you @haircut313 for sharing the 1114 build for the T710. And thank you again @ripee for your sterling work here on this ROM.

Following @djcasl’s lead and successful report I did a clean install of the 20211114 build with nano20211112 Gapps and Magisk v23.0 on my T710, using TWRP 3.6.0 following exactly @ripee’s “FULL WIPE (with external microsd card)” instructions. I can confirm that my T710 now exhibits no WiFi issues and no streaming issues either. In fact it looks to be a very stable software version, and it makes the T710 into a super-modern tablet. I was able to use the PlayStore reset trick to reload all streaming apps and they all work just fine, although I know I could also have loaded via APKmirror.

I will keep running this 1114 build until there is resolution of the two regressions that were introduced after the 1114 build. Specifically:

1. On every build subsequent to 1114 there are two bugs I have found in the WiFi subsystem.

1a. Bug 1 manifests itself as a hang in networking which is triggered by the tablet switching router in a Mesh setup, and usually shows as an inability to recover without at minimum turning WiFi off and back on again, and sometimes needing a tablet reboot. On 1114 the Mesh router switchover is seamless without any noticeable interruption, even if there’s a stream running. The WiFi bug is very easy to reproduce now we have clarity on what triggers the bug: yesterday I carried by T710 running 20211114 and my T810 running 20211123 slowly from one end to the other of my house (which has ASUS AiMesh running on two AX88Us at either end of the house), and today I did the same around my office. On both as I walked the WiFi signal strength icon dropped to 75% and then when it hit 50% close to another router at exactly the same time the T710 switched router seamlessly and showed 100% whereas the T810 disconnected. I can only recover the T810 by a reboot – switching WiFi off and on doesn’t clear the fault on the T810.

1b. We have a secure BYOD network in our office for tablets etc. For connecting to the BYOD network from vanilla Android 11 devices a WiFi certificate is required to connect, since Google is now enforcing certificates for secure networks. I have the correct cert, etc. With 1123 I was never able to connect. With 1114 the connection worked fine first time when I connected today.

2. On every build subsequent to 1123, commercial streaming apps such as Peacock, Disney+, and Netflix do not work. The apps start and then freeze on their splash screen. On 1123 and earlier all those apps load and stream fine.

I hope those descriptions will help you developers figure out and fix the regressions and produce a fixed build in due course along with whatever improvements that were put in the post-1114 builds.

I do have one request: does anyone have the T810 equivalent ROM dated on or around 1114? On my T810 I’m running the 20211123 build which streams fine if the tablet stays in one place, but exhibits the WiFi bug whenever I move around my house! Thank you in advance!
[Galaxy Tab S2 Android Development] bmwdroid:
@pflyaz I can offer lineage-18.1-20211103-UNOFFICIAL-gts210wifi.

That's what's still on my T810 having no WiFi probs.
[Galaxy Tab S2 Android Development] pflyaz:
That would be great. Thank you!
[Galaxy Tab S2 Android Development] bmwdroid:
you've got a mail
[Galaxy Tab S2 Android Development] halloarno:
Maybe you can share here?
[Galaxy Tab S2 Android Development] bmwdroid:
only if dev allows me to.

But I can send you a 24h link if you wish.
[Galaxy Tab S2 Android Development] halloarno:
Confirm, WiFi problems returned. Still try to figure out, when and when not.
[Galaxy Tab S2 Android Development] helipus:
I would like to have this too. Please share or send me a PN
[Galaxy Tab S2 Android Development] halloarno:
That would be nice, yes please, thx.
[Galaxy Tab S2 Android Development] bmwdroid:
@helipus @halloarno you got mail
[Galaxy Tab S2 Android Development] pflyaz:
I can report to this forum that I have fully functional Tab S2s, both a T710 and a T810, running LineageOS 18.1. Thank you to @bmwdroid for the T810 20211103 ROM and @haircut313 for the T710 20211114 ROM. I have solid and fast WiFi, access to all the commercial streaming apps I subscribe to, and everything else I use the tablets for is working fine with no glitches.

Here’s what I did to get to this good state:

1. Used TWRP 3.6.0 and followed exactly @ripee’s “FULL WIPE (with external microsd card)” instructions

2. On T710, installed 20211114 build with nano20211112 Gapps and Magisk v23.0

3. On T810, installed 20211103 build with nano20211103 Gapps and Magisk v23.0

4. After all my Apps were restored by Google, I completed the Magisk install.

5. After the reboot, confirmed Google Play Services was hidden in MagiskHide.

6. Cleared cache and storage from Play Store and rebooted.

7. After waiting a few minutes, I was then able to install Peacock, Netflix, and others from the Play Store.

Hope that helps others. The Tab S2s are terrific tablets and now they have the latest Android software running and fully functional on them.
