Hi there,

I wanted to flash this ROM on my T815 device but I currently have stock Nougat on there. Just to check the installation process I need to go through to make sure I don't mess anything up:

1) Flash TWRP recovery from here - TWRP 3.1.0-1 - SM-T710/715/810/815 - update 13/3/2017. Using instruction from here.

2) Flash the ROM for the T815 using the same instruction (again from here).

3) Root using Magisk?

Just want to make sure I don't brick my device. It works perfectly on stock but I would like a nice update for it. It's been a very long time since I ran a custom ROM on an Android device (used to do it a lot) so just clarifying that I'm doing the correct thing.
[Galaxy Tab S2 Android Development] dombo1970:
You should use this TWRP.
[Galaxy Tab S2 Android Development] madindehead:
Thanks. Not sure why I didn't spot that one. Too many recovery threads kicking about. Other than that, my steps are correct?

Update: All installed properly. Thanks for the correct recovery link. Really nice ROM so far - thanks ripee.

Glad I'm not the only one. I had less problems with the 15.1 image. (after a bit of playing got the same kind of artefacts, but the game usually didn't crash after 1-3 races)

I've been messing around with some settings with hKtweaks and found the CSR 2 game more stable with:

cpu governours set to ondemand

GPU max freq to 800

GPU min freq to 350

GPU voltage +12.5 mV

GPU Highspeed Clock to 730

GPU Hispeed Load to 90%

I got some base settings and the tip for the tool from a fellow developer of [MENTION=6005084]ripee[/MENTION]. (couldn't find the name of anan1211 who's in our dev chat inhere)

Edit: I just switched back to 15.1, installed the same tool and noticed that the GPU Highspeed Clock there is only 420 instead of 677 in 16.0. Will need to test a bit more. Setting CPU to ondemand makes scaling up a tad less agressive, probably resulting in less heat. The strange effects I see in 16.0 almost from the start are the same on 15.1 after a while of playing (device heating up). In 16.0 there is a safety option where the GPU is tuned down when the device gets to hot...

Great job on keeping this device up to date. I'm currently experiencing a problem with the screen lock in settings, whenever I try to set a screen lock the settings app keeps crashing (build 20191016). That's the only thing that bugs me, still many thanks for your ongoing effort.
[Galaxy Tab S2 Android Development] Davivigo:
Build 20191016 working! Offline charging and power button bugs are solved. Very impressive job!

Only GPS and fingerprint from sleep mode bugs seems to persist on my T715. But at this moment I can work fine with it at a daily use. Very very smooth and stable.

Congratulations and thank you very much for your effort, our old devices will have a longer life :good::good::good:

[Galaxy Tab S2 Android Development] samus777:
Nup the previous builds for me have never had the latest security patch but since the 16 Oct build change log specifically stated it should be the latest security patch I thought I would ask.

Deep sleep is working fine, so battery life is very good. No issues.
[Galaxy Tab S2 Android Development] ripee:
Sounds like a ghost in the machine. Flashing stock then going back to Lineage would fix it but I'm not sure of any less drastic fix.
[Galaxy Tab S2 Android Development] jaquedeth:
All right I am completely flummoxed. Still having an issue with the phone audio coming out through the bottom speakers on my T715Y. I tried re-flashing the stock firmware and phone audio worked as normal. Then I clean flashed lineage-16.0-20191016-UNOFFICIAL-gts28ltexx and the call audio still comes out the bottom speakers. I can not imagine what could be wrong. If anyone has any ideas I would really appreciate it.

Kodi - Touch screen accuracy

I have installed the Build 1019 on my T810 and I must say that so far I am impressed - many thanks.

The one problem I am having is with Kodi. Touching the screen to select an option results in a different option being actioned. Does anyone have a working "skin""?

Thanks

Slow charging

Has anyone experienced slow charging with this build? Having moved from 15.1 lineage it seems very slow charging although i'm using the same original samsung charger
[Galaxy Tab S2 Android Development] Daemongelius:
Everything seem to be working(T715 2015) except for the calls, same issue as jaquedeth. (Full Wipe so no dirty installation)
[Galaxy Tab S2 Android Development] Davivigo:
Is GPS working on your device? Is one of the old bugs on any S2 developement. Still not working on my T715.
[Galaxy Tab S2 Android Development] dannychow:
I just moved from stock 7.0 to LOS16 (lineage-16.0-20191019-UNOFFICIAL-gts210ltexx) on my T815 device. I 'm so impressed on the smoothness and stability on the build! The LTE data, Wifi hotspot and VPN works well. The battery life is also good.

The problems I found so far:

1. Screen Cast doesn't work. It can't find any remote display.

2. GPS doesn't work. It can't get any signal.
[Galaxy Tab S2 Android Development] Daemongelius:
Yes the gps is working(tested with some apps without problems) but i just found unlocking with the fingerprint is a bit "janky" sometimes. So my problems are the calls and the fingerprints.
[Galaxy Tab S2 Android Development] happy44:
How to update?

:confused:I apologize for this question. :To "update" to 1018 - this means to install the new full image via TWPR, doing a backup via Titanium beforel

The "update" dialogue in Settings will not work, as this is a not an official Lineage custom rom.

Correct?

Why I am asking:

I do have another phone with "official Lineage" - it does update automatically.

So, maybe I am just missing the point?

Thx again
[Galaxy Tab S2 Android Development] paul c:
System update option is not available. Depending on what you are updating from - if it's a recent LOS16, your could just dirty flash:

Go to TWRP, run a full backup just in case, and install the latest zip on top.

Dirty flashes are fast and convenient, but they may introduce errors. Shouldn't, but it's a major variable if you begin to see errors you didn't have before.

So the recommended way is to do your TB, take a Nandroid backup in TWRP, clean everything then flash the new release and then restore TB.
[Galaxy Tab S2 Android Development] Davivigo:
Yes, fingerprint is another little bug, most of the times when the device is on sleep mode. The light of the buttons don't work toó.

Impressive work by developers anyway. Very stable and smooth ROM. Great battery life.
[Galaxy Tab S2 Android Development] Daemongelius:
My menu and back button have the light on my t715.... This is strange ahahah :D
[Galaxy Tab S2 Android Development] dannychow:
I just found a new build (1021) in the build folder. And I tried the lineage-16.0-20191021-UNOFFICIAL-gts210ltexx on my T815 device. I find that the GPS problem is fixed for T815!

The only problem to me so far is the screen casting.
[Galaxy Tab S2 Android Development] Daemongelius:
So i tried a bit the last release on the sm-t715

Casting > Ok

Wifi > No problem excepted one crash, needed to reboot the device

4g > Ok

Battery life > Seem to be the same as the original or better, need more time.

Camera > Sometime black screen so after a reboot everything back to normal

Sound > Ok

Calls > The sound is distorted(only with the calls), the speaker at the bottom are always on and i can't change to the upper one. Another thing is the person i call can here is own voice like a echo.

Fingerprint > Like i said some time doesn't work but no a real problem for me.

Button light > No problem at all

Overall > No crash on apps, seem to be reliable, Thanks Ripee and sorry for my bad english :)
[Galaxy Tab S2 Android Development] Davivigo:
Build 20191021 working last two days. The 1st flash buttons light didn't work, but it was solved with a reflash. GPS seems fixed too, it was one of the classic bugs on every build. It's working perfect now, the only bug is the fingerprint coming from idle, but it's not a worry. The battery life looks great, it only drops 1% in the night.

Better than stock ROM by far... :cool:

Thanks and congratulations to the developers! :good::good::good:
[Galaxy Tab S2 Android Development] dannychow:
Just tested the screen casting for this 1021 build on my T815. It works also!

Hi, I upgraded my T810 from 15.1 to 16.0 (1021) yesterday and it is fantastic! Thanks so much for all the hard work! I've been anxiously watching this thread for months waiting for a stable Pie version. So far, no problems at all, everything works.

Is there a way to see battery percentage all the time in the notification bar? (I know I can swipe down.)

Thanks!
[Galaxy Tab S2 Android Development] khaberz:
Settings -> System -> Status Bar -> Battery Percentage
[Galaxy Tab S2 Android Development] js-xda:
Just curious: Did you manage to upgrade with a dirty flash or did you do a clean install? Upgrading from 15.1 to 16.0 is also on my to do list for later this week.
[Galaxy Tab S2 Android Development] frizzo999:
I did a clean install after full TWRP, Titanium, and Nova Launcher backups. I flashed the ROM and Mini GApps, signed in and Google restored most of my apps and settings. Some apps were installed but did not have previous settings, so I restored their settings using Titanium. Any missing apps, I can restore apps + data using Titanium. Nova Launcher backup restored my Home screens perfectly.

In the end, it took longer to do the backups (which I'd have done before a dirty install anyway) than the clean install/set up, and I didn't want to worry about problems from a dirty install.

Today hardware button backlight started working automagically after being inactive for months/various LOS 16 builds...keypress vibration feedback only works when power is plugged in...Spooky,isn't it? ?

Fingerprint sensor unlock only works 1 out of 100 attempts, but reproducible while listening to music - at least this is explainable as reliable fingerprint sensor and deep sleep seem to be mutually exclusive.

BTW - with the T715, 20191021 build battery consumption has significantly improved, now getting around 0.5 to 1 days more lifetime than with previous builds.
[Galaxy Tab S2 Android Development] numbfall:
can anyone on T710 check if auto screen rotation is working? mines not working since the 1021 build. apps that force screen rotation work such as mx player but os level screen rotation sticks to either orientation and does not go back unless i use a video app to reorient it again by playing a video vertical for example.

Hi everyone,

I'm about to flash this ROM on my T715 device. I currently have stock Nougat on. Just to be sure about the installation process, kindly see if I got it all intact

1) TWRP recovery already flashed (used it awhile back in flashing viperfx) TWRP 3.1.0-1 - SM-T710/715/810/815

2) Next, Flash the ROM (and gapps - pico) for the T715 using the same instruction from OP (without ext sd and no home PC method)

Done?

Or do I need to (3) Root using Magisk? (Already have supersu from previous usage of twrp for viper fx)

Edit : Installed and running, great rom :good:
[Galaxy Tab S2 Android Development] mxxt01:
Don't forget to back up all data!

You can't go wrong if you follow the instructions in the OP.

And don't forget to wipe and format data.

Once you finish you can root or not, as you wish.

I'm pretty much a noob but I did it [emoji6], I had troubles only becase I flashed first wrong TWRP and second wrong Gapps... But got all sorted out with some help from kind users in this thread [emoji28]

[Galaxy Tab S2 Android Development] ripee:
If you use up the tablet's battery power until it shuts down, it may take a long time for it to charge up enough to be able to power on. Remember that, in order to fully turn on, it needs enough power to go through its boot process. Also, the initial power-up sends a small surge of power through the mainboard when it powers up, which uses up more power momentarily than the tablet needs to finish booting up, or for standby.
[Galaxy Tab S2 Android Development] camdadeye291:
No, it is definitely not that, I let it charge for some time before I try to turn it on. The screen seems to activate but there is nothing displayed on the screen and it won't turn on if I hold the power button. Also, normally one may press/tap the power button to display the battery charge level but it does not show anything. Have you tested this? Perhaps you have the same issue. Just try turning your tablet off and charging it. Thanks for the quick reply. I have been using your ROMS for some time now, I am really grateful for your work, thank you.

* Synced with LineageOS sources.
[Galaxy Tab S2 Android Development] js-xda:
Running initially on LineageOS 15.1 July build and now 16.0 191101 build on my SM-T710, I observe in wifi networks with mesh (AVM Fritz OS 7) or at least multiple access points with same SSID (hotel, unknown hardware and settings) some issues:

several seconds and sometimes multiple attempts until initial connection

loss of connection - probably when swapping between access points (especially noticeable / annoying when using VPN)

Anyone else observing similar behavior? I found the below changelog entry but couldn't figure which "wifi issues" were referred to.

At the same time, I don't observe this behavior on two other devices running LineageOS 16.0.

Does this bug appear when you try turning the tablet on while it is still plugged into the charger, or after you unplug the charger?
[Galaxy Tab S2 Android Development] camdadeye291:
It seems that it is unrelated to turning it on. The error occurs when I plug it into the charger when it is switched off. After connecting the tablet to the charger the charging screen is displayed, the screen with the battery icon, and then the screen goes blank. The battery icon comes up for a moment, then the screen goes blank (The device is charging though, I know because when I turn it on it will have gained battery). After this the device will not turn on unless the 3 button combo is performed. I am sorry but I do not know a better way to describe it. Have you tried it yourself [MENTION=6005084]ripee[/MENTION]? I have an SM-T810. I had been upgrading for some time and thought that maybe a clean install would fix the issue but it did not.
