My tablet (T810) is hanging from time to time completely (100% busy), and the restart is very difficult to handle (via download-menue).

When off it's also difficult to bring it to live.

Also still missing the charging animation when power-off and pressing power-button for a short time.

There's something wrong is the last builts, guess since September.
[Galaxy Tab S2 Android Development] Ekstr:
0914 T810 Clean flash, data & caches wiped.

Performance and snappiness have gone up, though I experience slowdowns when tablet has been on for a longer period. Also app switching starts to lag and finally hangs when about 6 or more apps are opened. In games audio starts to stutter and hang after that sometimes.

Also tablet is running hotter than before. Especially while running games (which run smoother now btw :))

See attached logs for more info, hope they can help :)

Need to do more testing, more info later...

Awesome battery life
[Galaxy Tab S2 Android Development] tripLr:
My 710 has better than stock battery life.

Niagara launcher

Pico gapps.

Super impressed.

Thanks to the devs, especially ana n for hammering out the code and blips for the note 4 exynos chipset.

Thanks [MENTION=4637718]ananjaser1211[/MENTION] for the ride

Changelog

Pie build 0918 for all variants

* LiveDisplay is fixed, courtesy of [MENTION=4637718]ananjaser1211[/MENTION]

* Synced with LineageOS sources.
[Galaxy Tab S2 Android Development] Ekstr:
Holy sh*t, 0918 build feels amazingly fast, responsive and very snappy. Didn't know my T810 was capable of being a powerhouse :cool:

Didn't experience issues so far, only app switching performance decreases with about 6 apps open. But this could be hardware limitations as it's an older model I guess :)

I attached Syslogs to this post for no specific reason other than maybe being useful to somebody. Happy to supply more logs if needed.
[Galaxy Tab S2 Android Development] dombo1970:
Any idea how to fix this difficulties-to-turn-the-device-on problem? :confused:

"Not turning it off at all" is not the solution, because I had several times a complete hanging of the system (even with the 0914 ROM), so a restart was necessary but difficult to make. :(

No change with the 0918 build so far (but also not mentioned in the changelog, I know).
[Galaxy Tab S2 Android Development] numbfall:
can confirm. 0918 build feels much snappier on T710.

GPS

Hi, ,the GPS is not working on my T715. Does anyone else have this problem?

Power On doesn't work properly, too.

Great job anyway! Hopefully they will be fixed... Thank you very much!
[Galaxy Tab S2 Android Development] DPit123:
Thank you [MENTION=6005084]ripee[/MENTION] for keep working on this ROM. I was able to find a work-around for the slowdown issue that I've encountered on my T710 by limitting running background processes. As reported by some people, my tablet had random slowdown issue when there were 6 or more apps opened.
[Galaxy Tab S2 Android Development] FranciX03:
I can confirm that the latest build available (1809) has gps running
[Galaxy Tab S2 Android Development] srvoleti:
Yes, I confirm the same issue on my T815 also.
[Galaxy Tab S2 Android Development] Davivigo:
Thank you, then I'll have to check the GPS antena...

Great job, anyway. It's great to see our S2 running Pie! :good::good::good:
[Galaxy Tab S2 Android Development] DuckLabs:
Thanks for the responses to my power issues, but I already had tried the Odin of the .tar firmware files and reflashed TWRP 3.3.1 image file through existing TWRP 3.3.1

Now after no more modifications nor upgrades it has fixed itself. Maybe it was an app that updated in background that fixed itself...

That's for the advice either way!
[Galaxy Tab S2 Android Development] m2thedeep:
I'm seeing the same exact thing. Today I took my tablet off the charger in the morning and at noon when I powered it on, the battery was down to 60%. It looks like the tablet is not powering down fully.

What do you think it was? Im still having this problem.
[Galaxy Tab S2 Android Development] chigo58:
At the risk of sounding like a dumb question.. can I just flash 16 over the latest 15?
[Galaxy Tab S2 Android Development] bmwdroid:
You can give it try but I would strongly recommend to do a clean flash.
[Galaxy Tab S2 Android Development] partofthething:
Also seeing hard hangs every once in a while, often when opening an app that accesses storage (like VLC). Also have a SM-T810 and have an absolutely clean flash of 2019-09-05 build (which is otherwise super awesome, btw). If it keeps happening I'll try to learn how to collect logs and add some useful information other than the fact that it's happening to me too.

0920 online, just flashing. What's new?
[Galaxy Tab S2 Android Development] mysa50:
Hello, just dirty flash 0918 build, smoother than previous one on t710, no major bugsr but live display still doesn't work for me.maybe a factory reset would help.

Anyway that's really great to run lineage 16 on my tablet.

Great works from devs
[Galaxy Tab S2 Android Development] Davivigo:
Build 0920

I´m trying the 0920 build on a clean flash. It looks great; the power-on bug seems to be fixed! I´ll test the GPS later, it was the another only problem that I´ve found on the 0918 build.

Very great job by the developers, my T715 would have been retired without this. :good::good::good:
[Galaxy Tab S2 Android Development] srvoleti:
Yes, only GPS is not working for me so far T815, auto brightness is slightly buggy and is brighter. Not a big problem! [MENTION=6005084]ripee[/MENTION] thank you again and again for extending support for this tab!
[Galaxy Tab S2 Android Development] Davivigo:
We can wait for GPs, no problem :cool:

Power-on issue has come back... The only way to turn on the device is through Download mode.

TWRP issue, maybe?
[Galaxy Tab S2 Android Development] m2thedeep:
I'm still on 0914 but what I found is that the power issue only occurs for me if I try to power on the device after it's been on the charger. If I close all apps and turn off the device (while not charging) , then turn it back on, all works as expected.

Right now my solution is to keep the device on while charging and then turn it off once I disconnect the charger.
[Galaxy Tab S2 Android Development] Davivigo:
Yes, I'm trying with 0920 and I've noticed that. The charger must be disconnected BEFORE turning on/off the device.

Maybe this information will help developers to fix it...

Tried latest build 20/09 on T815Y. Everything is working, including phone, camera, and GPS. Power is draining a bit. About once every one-two hours tablet starts slowing down then hangs completely, requiring reset through three-fingers switch to download mode.
[Galaxy Tab S2 Android Development] srvoleti:
Is GPS working for you? It's not working in my T815 with 20/09 build. Can you please reconfirm?
[Galaxy Tab S2 Android Development] alexeyp:
Yes, GPS is working for me.
[Galaxy Tab S2 Android Development] FranciX03:
With the latest version of the rom available, fingerprint recognition has improved slightly. Stability and fluidity is greatly increased instead

I think there are few things that make this rom perfectly like the previous Lineage 15 based on Oreo:

Unstable fingerprint recognition (even if facial recognition is very fast)

And the ignition after making it charged by off, which forces a forced restart

Anyway, congratulations to the developer that allows us to keep our devices with Android 9 Pie alive and fluid !!
[Galaxy Tab S2 Android Development] mtnez.david:
Testing last version as well, I agree with FranciX03, congratulations!!
[Galaxy Tab S2 Android Development] CuckooPenguin:
Hi all,

Started with fresh clean install ...and now working my way to reinstall apps and connectivity.

So far all seems to work, even netflix + magisk + props editor/fingerprint :)

Now found BT is not working, i find devices - but pairing and connecting fails.

Did full network settings reset - but do not manage to connect my echo dot for instance (worked fine in latest 15 image)

Anyone else having issues with bt ? Any tipps - otherwise i will start fresh again and test bt asap.

Otherwise image works great, gps, audio, video, youtube (*thumb up*).

Edit: BT works as expected, 0920 image fresh install.

Another sm-t810 here, great ROM really breathes new life into this tablet. Only odd thing is it doesn't want to power back on from a off state as some have mentioned. Got it on by holding power, down volume, and home.
[Galaxy Tab S2 Android Development] mxxt01:
Hello everyone,

I want to flash the last ROM on my SM-T810. Can anyone point me to the right TWRP 3.3. please?

I can not find the right one for my tab...

I'm searching the forum as I'm new here but can't find a higher version than 3.1.

I'm on stock ROM Android 7.0.

I flashed TWRP 3.1.0-1 but I end with ERROR 7.

Install matlog
[Galaxy Tab S2 Android Development] Davivigo:
At this time I have been working with 0920 version from sunday. It works nice on my T715, but if some bugs were fixed it would be closer to perfection:

-If the charger is connected the only way for turn it on is Power + vol- + home (unplug it before turning off)

-GPS don't get satellites

-Some hard hangs (using Chrome only, I guess)

WiFi, Bluetooth, and all of the other features works great!

I don't know about using Matlog but I'll try to get data. Maybe we could help to improve this amazing build :cool:

In order for the Netflix app to appear in the Play Store, you would first need to flash Magisk then possibly toggle Magisk Hide off and back on in its settings. I updated the latest build fingerprints in all 4 variants, so those will help pass SafetyNet that is a requirement of Netflix appearing in the Store.

Without Magisk, you're stuck sideloading the legacy version.
[Galaxy Tab S2 Android Development] mtnez.david:

Ok, There should probably be a bit of editing for the guide, with a few extra links. For idiots like me.

'gts210vewifi" - 2016 Model. Newer GPU and "arm64"

But according to the review information, the 2015 is able to process arm64.

Why does lineage require "arm" for it?

Maybe just the fingerprint unlock, sometimes works sometimes not...

Hi all,

Working with a clean build (0924 / T810) I am unable to play downloaded videos from Google Play Movies. I can stream all I want; however, as soon as I download the movie/TV show I am prompted with a black screen which helpfully says "There was an error." and no further context.

Deleting the download and going back to streaming works just fine.

Not sure if it's an edge case or just something I'm missing. Happy to provide logs or whatever is helpful to troubleshoot.

The last two builds (09/20 and 09/24) keystroke vibration and hardware key backlight stopped working here (T715). Vibration is working in TWRP, so hardware defect is unlikely. Anybody else seeing this?
[Galaxy Tab S2 Android Development] samus777:
Flashed the 0924 rom clean install for T815y and everything has been working great so thank you so much for bringing new life to my device.

I did find one bug where the fingerprint reader sometimes doesn't work on the lock screen. Once unlocked any app using the fingerprint reader works. Anyone else experiencing this issue too?
[Galaxy Tab S2 Android Development] numbfall:
Yeah. Fingerprint unlock only works 1/100 times.
[Galaxy Tab S2 Android Development] chlrbwls:
The only way i have been consistently get fingerprint working in my T710 is by ensuring that i use the lock button to lock the device. If the device ends up going to sleep then to lock from inactivity, the fingerprint scanner does not work. I have the folio case and i have the habit of closing it. But locking it manually ensures that the reader works on the next time it is awaken.
