I used version 3.2.3 from here: https://dl.twrp.me/gts28vewifi/

That was the latest version when I flashed it earlier this year. You'd probably be better off using the current version, but I can confirm that 3.2.3 worked well.

Thanks! I have an older version & flashing this ROM wouldn't work. Dumb question: can I flash a newer TWRP from within TWRP or do I need to use ODIN?

Odin for flashing twrp
[Galaxy Tab S2 Original Android Development] Dr. Drax:
You can absolutely upgrade TWRP from within TWRP. Once TWRP starts, it stays completely in RAM, so overwriting the recovery partition isn't a problem. From the TWRP's Install screen, select the button to install an image, and just select the appropriate .img file. Reboot into recovery, and you're done -- much faster than dealing with Odin, especially if you're already putting files on your SD card to flash.

I just re-verified this by upgrading to TWRP 3.3.1 from within TWRP 3.2.3.

BTW, yesterday I installed the 5/23 nightly on LineageOS and the 5/23 Open GApps ARM64 9.0 nano version. I've only used it for a day, but so far it seems solid. Some people have complained about battery drain, but I left it unplugged overnight (about 9 hours) and my battery only went down by 3%, so this version doesn't seem to have that problem.
[Galaxy Tab S2 Original Android Development] :
The most convenient option is to use the TWRP app. With it one can update TWRP directly from the OS. It's on Google Play.
[Galaxy Tab S2 Original Android Development] lmacmil:

Bug: drop-down lists in dialogs

Edit: This problem only happens with Expanded Desktop (or immersive mode by any other name) enabled.

LineageOS version: 16.0, 5/23/19 nightly

LineageOS Download url: https://download.lineageos.org/gts28vewifi

Gapps version: Open GApps nano, 5/23/19 build

Did you-- wipe: yes

restore with titanium backup: no

reboot after having the issue: yes

Are you using--

task killer: no

a non-stock kernel: no

other modifications: Magisk 19.2

Drop down lists in dialogs aren't appearing properly. I've included two sets of screenshots. The first two are with Display size (in the Display section of syste settings) set to Large, the second two have it set to Largest. You can see that the lists are offset and truncated. If I set Display Size to Default or smaller, the drop down lists don't appear at all.

Duo Echo/Reverb

Hello,

Whenever using LineageOS (latest build) with Duo, one or both sides of the connection experience extreme reverb (hearing their own voices). It's like noise-cancellation or echo-cancellation is not even enabled. I took one of the SM-T713 tables I have and reverted it to the latest, stock Samsung build, and there is no issue with reverb.

Not even sure how to go about troubleshooting this, but I would love to be able to use Duo within LineageOS.
[Galaxy Tab S2 Original Android Development] weinbers:
I have the same problem with Duo on Lineageos 16.
[Galaxy Tab S2 Original Android Development] deejayjaytay:
I've searched around, and either my searching skills are awful, or no one has said much of anything related to either this device or LineageOS. It has to be LineageOS, however, because I do not get the issue with the stock OS. Huge bummer.

I'm running the May 8th build and battery drain is very good. Anyone running a recent build with good battery life?
[Galaxy Tab S2 Original Android Development] openletter:
None.

I recently purchased the S2 so I could have a non-discontinued tablet with Lineage OS. When I got the new-to-me device, the first thing while still having the stock ROM that I did was see how long it could run a 1440p YouTube video, just to make sure the battery was acceptable. I used one of the test videos and it ran for just over 6 hours before hitting 5%.

I've been updating maybe every 3rd day or so, and have yet to go a day of light use without being annoyed that the battery is almost done. It is currently the worst performing LineageOS build I've ever experienced.

Current battery usage:

47%

Charged 16 hr ago

YouTube 15%

Used for 47 min

Firefox 4%

Used for 16 min

Amazon Kindle 2%

Used for 11 min

Google Play Store 1%

Google Play Service 1%

Edited to add:

In looking at my above post, I think it sounds more negative than I meant to communicate. Most of the battery drain issues get fixed over time, and daily builds at least superficially indicates the devs will eventually resolve the issue.
[Galaxy Tab S2 Original Android Development] lmacmil:
It's an established fact that LineageOS battery life much worse than stock. I use about .3%/hour at idle (typically with wifi off) and 20%/hour n use. My usage is mostly Chrome, some emails, and very little YouTube.
[Galaxy Tab S2 Original Android Development] openletter:
This is only my 4th tablet with LineageOS, but the battery life seems much worse than I experienced on previous devices, which I didn't even really notice if the battery drain was worse than stock.
[Galaxy Tab S2 Original Android Development] tensux:
battery life for me was much better in the older builds.

It used to seem to shut wifi off by itself. As when you were waking the tablet up you would notice the wifi connecting. Now when I wake the tablet up it is already connected and wifi is the showing the reason for most of the battery drain.

I posted about this earlier - see https://xdaforums.com/showpost.php?p=79611850&postcount=247 - but didn't realize the extent or the context of the problem.

When immersive mode is enabled (regardless of the method, but I used the built-in settings Expanded Desktop toggle), many apps develop UI issues. The drop-down box issue I provided screenshots for in the previous link are just one example. There are a bunch of (harder to screenshot) problems in a variety of apps where highlights upon tapping something are offset both horizontally and vertically from their proper position, or pop-up menus appear in the wrong place on the screen. Turning off immersive mode immediately fixes the behavior - no need to restart the app.

It has the feel like some subsystem or API has providing incorrect information about the screen size when immersive mode is enabled, and so it only affects certain display items. But that's pure speculation on my part.

Are there full installation instructions anywhere if coming from stock (or stock rooted)? I am on the January 2019 Nougat build currently with Magisk 19.3 and twrp_3.1.0-1_sm-t713_14417n. I reinstalled the Feb 2018 build (the only .tar I had archived) in Odin a while back to get rid of any remnants of XPosed or SuperSU and do some general cleanup. I accepted the update to January while I was still unmodified immediately after flashing factory. Clearly, the instructions in the OP are to update from existing LineageOS, but some of the recent posts have me about ready to try this version.

[Galaxy Tab S2 Original Android Development] sliding_billy:
I am at an impasse. Obviously, install went fine and the tablet took root. Set everything up. Rebooted a few times towards the end of setup, and the last time I rebooted it get to the lock screen, acepted my PIN and kept going back to the lock screen. I even heard notifications dinging after it was back in lock screen, so it was still processing boot apps. I'd still like to hear any thoughts, but I reinstalled from scratch (including wipes). I just got back to the "hi there" start screen.

*edit* I am not certain what I did that got me through to where I am now comfortable with some questions. I did 5 or 6 reinstalls after the one that started this issue. I was pretty convinced it was related to Magisk, so I tried different things with Magisk during different installs. None got me past a reboot after granting the first app root privileges. Everything seemed normal, but it wouldn't clear the lock screen (it was fine after Magisk was installed and rebooted, and even had no problem entering Magisk and setting it up and then rebooting. Finally, I broke down and installed addonsu. I installed it after LOS and Gaps with a sideload. It did NOT give me root privileges, so I went back to recovery and "installed" the .zip. Still no root, but nothing had failed yet, so I installed Magisk. I granted one app root privileges, and rebooted. No issues, but that still made no sense. I kept installing and rebooting when I thought it might fail again. The only other things different in this the final install install were NOT setting up a PIN during setup (I am still hesitant to set one up) and not turning on auto-rotation during post install setup.

On the plus side, I have everything set up and configured and it is screaming fast. I love this ROM. I just wish I knew what the hell solved my initial install issue.

Early returns: Idle battery life much better

I installed nightly 0803 and can report back that over the first night of ~12 hours, I lost 0% battery. I'll report back if this doesn't continue, but this is a MASSIVELY better result than I was getting when I tried LineageOS ~6 months ago. If this holds, it extends the life of the tablet by a significant amount. Great work, Luk1337 and Deltadroid!

Edit - it looks like actual battery use is about 0.3% per hour with Wifi on. I'm now testing with Wifi off to see if there is a difference. My next step may be Greenify or Naptime, to see if that number drops. On stock, it's 0.1% to 0.2% per hour.

Edit 2 - Still having unexplained high idle battery life, and I've dug into Battery Historian, Accubattery, GSAM, etc. I absolutely appreciate the work that goes into maintaining this ROM, but I'm running one more test, and then just going back to stock, which just released a new firmware version with the July 1 security update. The security update is primarily what I was after in the first place.
[Galaxy Tab S2 Original Android Development] Bad Liar:
I installed the latest update using Lineage Downloader yesterday as I tend to do every week or so. It seemed to go normally, and I flashed the update. The tablet booted into download mode rather than booting up the OS like normal.

I figured I had accidentally done something and just rebooted the device. It did it again, and again. I decided to boot into TWRP and see if I could boot into the OS from there, but it just brought me back to recovery.

In the end, I was able to flash the ROM, Gapps and everything else again, but it obviously shouldn't have been necessary.

I can't think of anything else that may have caused this.

Any chance that the nightly from August 7th caused the issue? Something to look into, I guess.

Update problem - question

Hi

I tried to install yesterday's update(09/08) using the lineage os updater, and the automated process doesn't work. I also tried to install the update manually (data --> lineage updates) but with no results ( i am getting the updater process ended with error: 7 ).

Previous day, the automated installation (08/08/2019) worked perfectly normal.

While trying to update manually, i get (except the updater process error 7) , the trust zone error. While searching, i found that this is due to outdated bootloader.

Any ideas ?

PS: last week, i had the exact same problem trying to update lineage on my poco f1. But i flashed latest firmware from xiaomi updater and i could get the installation of the new version lineage os.

Is it possible that's the case with Samsung? and if it is, where can i find the latest kernel version to install?

Or perhaps:

Should i install the permissive kernel ?
