Q2. Any chances of having L15 nightly for T713 anytime soon?
[Galaxy Tab S2 Original Android Development] LuK1337:
As soon as L15 source gets bit less ghetto and I finish up the SELinux.
[Galaxy Tab S2 Original Android Development] tensux:
i know this is talked about in other places..but i am getting system error 7 when trying to install this rom, i am using the custom recovery in the OP. can anyone help?
[Galaxy Tab S2 Original Android Development] timestryder:
I had to FORMAT DATA, and it went through.

What was your error message above the error 7 line? Mine was something along the lines of "cannot write over a package that already exists" or something to that nature.
[Galaxy Tab S2 Original Android Development] tensux:
thanks for the reply, i realized that it was also telling me that i didn't have the correct bootloaded installed, after fixing that i was able to install it
[Galaxy Tab S2 Original Android Development] timestryder:
Oh yeah. I'm totally new to all this, and I had that same error message at one point as well. I missed the part where you need a nougat bootloader for lineage.
[Galaxy Tab S2 Original Android Development] Lovelyven:
I installed it when it boots it says kernel is not seanseoid enforcing. It gets to the setup screen then when I click setup as a new device or copy your data it keeps crashing saying set up wizard has stopped then it repeats the process
[Galaxy Tab S2 Original Android Development] 360Razir:
Something that Lineage 15 has fixed is using Hangouts. This never worked for me on Lineage 14.1.
[Galaxy Tab S2 Original Android Development] DGooseman:
Amazing! Thanks alot! I'll wait installing until you have fixed SELinux and L15 is a bit more stable. I'm excited to try out Oreo on my tablet :D
[Galaxy Tab S2 Original Android Development] 4rz0:
So is it actually Android 7 or 8?
[Galaxy Tab S2 Original Android Development] Semmelknoedel:
I had the same problem with Stock Rom. Installing LOS 15.1 nighly build and format the SDCard solved the problem.

I have played video tutorials from lynda.com (= mp4 files).

mp4: Google Video Player stops playing video track after 3 sec (timeline toggles from 1 to 3sec) but audio track remains playing

MX Video Player: HW decoder video and sound are asyschron, HW+ decoder and SW decoder works

h264: Google Video Player no sound while video track ist playing
[Galaxy Tab S2 Original Android Development] martinistripes:
"SetupWizard keeps stopping"

"Setup Wizard keeps stopping"

Keep getting this^

I have latest TWRP (3.2.1-0)

Formatted data

Wiped dalvik, system, data and cache

Flashed LOS 15.1 (lineage-15.1-20180226-nightly-gts28vewifi-signed.zip)

Flashed Open GApps (open_gapps-arm64-8.1-stock-20180303.zip)

If I flash without GApps, the ROM works. Banging my head against a brick wall with this one and it seems few if any others here are having the same issue. I can't understand what I'm doing different to everyone else here. :confused:
[Galaxy Tab S2 Original Android Development] grakor:
Try formatting (not wiping) data and storage prior to flashing. Worked for me.
[Galaxy Tab S2 Original Android Development] imdatslaya:
Well I've flashed the SU and and no luck. How do you get root on this ROM?
[Galaxy Tab S2 Original Android Development] grncherry:
I was having the same or similar problems with sdcard access. Could see the card but there was no write access. TiBu wasn't able to gain access either to backup or restore. Something changed between the 02/09 and 02/26 nightlys. I'm inclined to think something happened with the platform.xml but I'm not savvy enough to know how to begin looking. I had to return to 02/09 version.

---------- Post added at 05:29 PM ---------- Previous post was at 05:26 PM ----------

Your best bet would be to use Magisk 16. Works for me. Good luck.
[Galaxy Tab S2 Original Android Development] martinistripes:
Did you read my post? :rolleyes:
[Galaxy Tab S2 Original Android Development] Deltadroid:
The problem is that open gapps is using an incorrect api version of google SetupWizard when a tablet is detected. You can try the Delta gapps that I posted. I just added the correct version of Google SetupWizard for tablets.
[Galaxy Tab S2 Original Android Development] martinistripes:
Thanks, could you link me to the Delta GApps you posted? Will it work with a gapps-config file?

[Galaxy Tab S2 Original Android Development] Sgace:
Just use the Gapps provided in the OP.

Cheers
[Galaxy Tab S2 Original Android Development] martinistripes:
Ok, got it working with MindTheGApps but there are too many Lineage apps for my liking. I'll go back to 14.1 until OpenGApps stock works and I can use a gapps-config file to pick and choose.
[Galaxy Tab S2 Original Android Development] Krystanos:
What link is there between mindthegapps and lineage apps?
[Galaxy Tab S2 Original Android Development] martinistripes:
The mindthegapps linked in the op doesn't overwrite lineage apps like opengapps stock does. And I prefer to have Google calendar, calculator, contacts, mail etc.
[Galaxy Tab S2 Original Android Development] Krystanos:
I see... Makes sense :)
[Galaxy Tab S2 Original Android Development] deejayjaytay:
New version came out today (lineage-15.1-20180305-nightly-gts28vewifi-signed.zip). Still getting the "corrupt" SD card problem when trying to use an SD card as internal storage. :(
[Galaxy Tab S2 Original Android Development] HaloTechnology:
Was going to ask about that guess we should wait till next week ?
[Galaxy Tab S2 Original Android Development] Semmelknoedel:
I still have the same problem with asynchroniuos video playback in google video player. The videos are stored in internal storage and also in external storage (as portable device). I go back to Nougat Stock Rom :(
[Galaxy Tab S2 Original Android Development] knoxjon:
I'm having trouble getting this ROM to deep sleep. I am assuming it's because you can no longer have wifi turn off automatically when the screen is off. Anybody else having this problem & found a solution?
[Galaxy Tab S2 Original Android Development] Semmelknoedel:
Interesting. In my case wifi turns automatically off when the screen turns off. But I have a problem with playing videos instead.
[Galaxy Tab S2 Original Android Development] knoxjon:
I haven't tried playing videos. Is it audio, too? I haven't had any trouble with audio.
[Galaxy Tab S2 Original Android Development] Semmelknoedel:
I have tried playing mp4 and mkv (h264) with google video player. Both without succes. Please see my other post for details. I'm going back to Stock ROM.
[Galaxy Tab S2 Original Android Development] Krystanos:
I have updated to 20180305.

Brightness seems to be fixed, it's not running at maximum brightness anymore (though automatic brightness seems to have issues still)

Looking for system updates is not raising an error anymore

Button lights are still a pain, but once disabled it's fine.

This version has fixed the biggest issue for me: the brightness (though I couldn't find anything in the changelog for that). I'll check the battery, because I find that the previous version was draining it fast. Also it's charging very slowly. But it's still a great job!
[Galaxy Tab S2 Original Android Development] knoxjon:
I updated to 20180305, but I am still unable to get deep sleep except by forcing wifi off. Turning off sync didn't help. It's especially frustrating that nothing seems to be happening to keep it awake. It mostly seems to be "WifiConnectivityManager Restart Scan."
[Galaxy Tab S2 Original Android Development] Ollebro:
Is anyone else having these two issues?

First, the device makes two "clicking" sounds every 5-10 sec, this regardless if the device is locked, if I'm watching something or what ever. I've even tried reinstalling 15.1 and I still get the sound with no applications open. Super weird. They arent connected to the sound level either, they sound quite low and it dosn't matter what volume the device is on.

Second, wifi sometimes die and it wont turn on until I reboot the device. Happen rarely but super annoying.
[Galaxy Tab S2 Original Android Development] lmacmil:
This happens occasionally on my T713 running stock Nougat.
[Galaxy Tab S2 Original Android Development] HaloTechnology:
Is the SD card fixed in today's nightly?
[Galaxy Tab S2 Original Android Development] deejayjaytay:
Doesn't appear so. :(
[Galaxy Tab S2 Original Android Development] Krunk_Kracker:
I'm having an issue, and I'm not sure why. I have Nougat lineage installed no problem, trying to upgrade, I get error 7 and told that it's not the right version. Anyone else have this issue?
[Galaxy Tab S2 Original Android Development] LuK1337:
Be more specific? I tested both usecases with fresh sdcard.

Old TWRP.
[Galaxy Tab S2 Original Android Development] deejayjaytay:
The card formats, mounts and the amount of total storage increases. But upon reboot (or sometimes multiple reboots), it gets marked as corrupt. I've used the same SD card (Samsung) in my girlfriend's tablet as external storage and it works fine.

I've even mounted the SD card on a Linux box, removed all the partitions, recreated one primary partition, and formatted it as F2FS before placing in the tablet, formatting again, and watching it become "corrupt" on reboot.

tl;dr -- internal storage becomes "corrupt" after a reboot or two, the other option for storage (removable?) works fine
[Galaxy Tab S2 Original Android Development] Krunk_Kracker:
I thought about that but didn't think that'd do it. Thank you!
[Galaxy Tab S2 Original Android Development] LuK1337:
Meh, i hate adopted storage ~ https://review.lineageos.org/#/c/209266/

15.1 downgrade

I have a 8" wifi S2, and TWRP is installed and working, and so is CM14.x..

If I flash CM15 with TWRP, can I revert back to CM14? I realize Samsung has added ant-theft 7 day delay for other tablets, like my SM-T380.
[Galaxy Tab S2 Original Android Development] Krunk_Kracker:
I'm getting constant Google Play Service errors, and the Play store will not load.

I tried it as an upgrade, and as a fresh install, and I used the "Mind the Gap" gapps. Still happening.

Going to try with Open gapps.

EDIT: Open GAPPS fixed it.
[Galaxy Tab S2 Original Android Development] ivanox1972:
Try to wipe cashe and dalvik after instal rom and gapss, jus before restart
[Galaxy Tab S2 Original Android Development] Krystanos:
I can't see the link between downgrading and samsung anti-theft thing...

I have aksed the downgrade question, and I got a "yes it's possible". But I can't guarantee it since I'm sticking to CM 15.1 for it's running fine for me (except battery life but I can live with it for a while).
[Galaxy Tab S2 Original Android Development] bart3005:
Anyone having wifi issues on the latest 0319 build? Works for a while 15 20 mins and then drops, after this can't see any wifi networks.
[Galaxy Tab S2 Original Android Development] josdehaes:
19/3 build seems to have fixed the deep sleep issue. At least in kernel adiutor, I see the cores go into deep sleep now :). Will see how the actual battery life will behave, as it was raining crazy fast before...
[Galaxy Tab S2 Original Android Development] Krystanos:
Good to know! Any issue with WiFi like [MENTION=3507927]bart3005[/MENTION]?
[Galaxy Tab S2 Original Android Development] josdehaes:
I didn't notice any issue yesterday on this build at least. I have in the past had intermittent problems
[Galaxy Tab S2 Original Android Development] Krystanos:
WiFi issue confirmed on 0319.

After about 20-30 minutes I got disconnected from WiFi network. I disabled and enabled again WiFi but it failed to enable again. Switching it on did nothing, it switches off right away.

Only a reboot fixes the issue.
[Galaxy Tab S2 Original Android Development] josdehaes:
Spoke too soon. Although device does go into deep sleep now, this afternoon if went from 61% to 17% without using the device at all. Kernel adiutor shows the little cores stuck on 691 MHz for over 5 hours and on 400 MHz for 3 hours... Big cores were asleep all the time. Battery percentage was flat lining for a while left night but something happened that made it lose charge like crazy....
[Galaxy Tab S2 Original Android Development] RagingHarry:
You might want to do a fresh install and install all apps manually (real fresh install, setup the device as brand new) and no reinstall of apps from cloud backup or titanium backup.

Solved my drainage from system, kernel and Google play services.

Running like it should here again, smooth fast and great battery life.
[Galaxy Tab S2 Original Android Development] josdehaes:
I did a fresh install some days ago (coming from the unofficial builds) but indeed restored from Google cloud backup. I could try the clean install again, but not tonight ;). Time for bed
[Galaxy Tab S2 Original Android Development] bart3005:
So had to reboot it to get wifi back.

Used it again last night and didn't do it. More testing needed on my part.
[Galaxy Tab S2 Original Android Development] Krystanos:
It happened only once yesterday on my side too, same behavior. Will keep this version a bit longer to test battery and wifi.
[Galaxy Tab S2 Original Android Development] Krystanos:
No issue yesterday about WiFi or battery...

However I came across an issue, not necessarily related to this ROM, but indirectly.

The Galaxy Tab S2 is doing wrong with games. They all are displayed huge and cropped, what causes issues of controls over the play zone for example. Samsung has a workaround for that: Samsung Game Tuner. It enables resolution change for games, what fixes the issue, even partially.

However, Game tuner (available on APK Mirror) does not work on this ROM. It requires the Game Optimizer Service that can't be installed. It must be only in the Samsung ROM.

I tried to use the resolution configuration in the LineageOS settings, but at game launch, it somehow either change the resolution back, or extend the game. Point is the result is the same as without resolution change.

Does anyone has a workaround for that? A game to validate the issue is The Room. At the very start, there's a letter. When reading it it is displayed behind the inventory controls. Just an example but the game is almost not playable because of that. And there's many games out there that have issues with resolution (and many that don't of course, but not the point here :))
[Galaxy Tab S2 Original Android Development] bart3005:
Noticed the tablet in my bag not being used from being 100% to 85% in about 8 hours.

Seems a little high.
[Galaxy Tab S2 Original Android Development] Krystanos:
Has anyone tested the 03/26 version ?
[Galaxy Tab S2 Original Android Development] SvenHee:
I have 03/26 running now, one (gapps)app force closes. I disabled it, no problems since.
[Galaxy Tab S2 Original Android Development] bart3005:
On the 03/26 build I had the wifi stop working again needing a reboot. Did it just the once so far.

Battery seems to drain slightly less.
[Galaxy Tab S2 Original Android Development] Krystanos:
Samsung Game Optimizing Service is crashing, preventing a lot of games to run "normally", probably because of the screen ratio?
[Galaxy Tab S2 Original Android Development] HaloTechnology:
So what kinda of bugs we still have in the latest build ?

Last time I tried this ROM the auto brightness wasn't working .
[Galaxy Tab S2 Original Android Development] rlw6534:
Still not working.... :(
[Galaxy Tab S2 Original Android Development] Chep2185:
Is anyone getting an issue were music in some apps and games is not working?

sound effects still work though

The WiFi stops working after being in sleep mode after awhile and I need to reboot my

tablet for it to work again, it seems to get worse if I change the TCP Congestion Algorithm to anything but the default of bic but it could be just a coincidence
[Galaxy Tab S2 Original Android Development] egenesis:
Anyone knows which keyboard layout file I will have to change so that the back button is on the left and recent app is on the right? I believe this has changed since 14.1

[Galaxy Tab S2 Original Android Development] bart3005:
On the 02/04 build I still have the wifi stops working problem. Also what's with the permanent davy Jones notification?
[Galaxy Tab S2 Original Android Development] grmcdorman:
The "Davy Jones" notification is the Lineage OS April Fool's joke. You'll also find a "Wallet" application installed.
[Galaxy Tab S2 Original Android Development] bart3005:
Yer and it says if you follow the link that it's an unofficial build. You can run a command to disable it.

Still having wifi issues. Not all the time but sometimes it just stops working and requires a reboot.

Best ROM however.
[Galaxy Tab S2 Original Android Development] HaloTechnology:
Does auto brightness works ?
[Galaxy Tab S2 Original Android Development] mccreary:
Adaptive brightness should be working in the April 16 build. We merged change 212619 to fix this today.
[Galaxy Tab S2 Original Android Development] Chep2185:
I'm still getting the weird music and sound effects not working issue on some games and apps.

Some have sound effects but no music and some music won't work unless a Bluetooth is connected.

Some examples.

MiniDayz- no sound even with Bluetooth

Guns Of Mercy- sound effects work but music doesn't unless Bluetooth is connected

Atmosphere Apps- some sounds work some don't but all of them work when the Bluetooth is connected

And the WiFi issue is still present
[Galaxy Tab S2 Original Android Development] stroths:
On the last several weekly builds, I have had lower than normal battery life. Looking at the CPU states, I can see it never goes into deep sleep. No particular apps are looking like the culprits, so not sure if it's something with the build or something I have running. Regardless, this is a great build overall and I'm pretty happy with it.

EDIT: Found a workaround for the deep sleep issue, but it's not ideal. I ran across a thread during a google search where the person was Oreo 8.1 on a different device and had the same issue. They found out that it was related to plugging the device into a charger. If you unplug it, turn off wi-fi, reboot and then turn wi-fi on again it would go to deep sleep again. However, plugging it into the charger would make deep sleep stop again until you follow this process. I tried it and sure enough it worked for me. Plugged it back in later that day and deep sleep stopped. Some thought it was a kernel issue, others wi-fi and some Google play services. Better Battery Stats doesn't show anything unusual, so I'll stick to this workaround for now.

Workaround

1. Turn off Wi-Fi

2. Reboot

3. Turn WiFi back on
[Galaxy Tab S2 Original Android Development] uscoofkf:
On-screen nav bar

Hello. On some other devices LineageOS has option in Settings/Buttons to "enable on-screen navigation bar and disable hardware buttons". I suspect there is some build option that enables it. Is there any chance that you'll enable it someday? It will be very appreciated.

BTW, thank you for the ROM.
[Galaxy Tab S2 Original Android Development] LuK1337:
Nope.
[Galaxy Tab S2 Original Android Development] uscoofkf:
Why?
[Galaxy Tab S2 Original Android Development] LuK1337:
Cause we can't disable home button.
[Galaxy Tab S2 Original Android Development] uscoofkf:
Well, yes, but that's not a problem. A lot of devices with hardware home button have this option enabled (to name a few I've owned and I know about: jflte, ham). Disabling only capacitive buttons is pretty enough. Finally, it's just an option, not default.
[Galaxy Tab S2 Original Android Development] LuK1337:
Sorry, I'm not including halfassed features.
[Galaxy Tab S2 Original Android Development] Krystanos:
Awesome! I was losing 30% in 12 hours of idle time, after the workaround I'm losing only 8%.

It's still high though, and it seems I didn't have the issue prior to April 1st version (but maybe I did not see it).
[Galaxy Tab S2 Original Android Development] stroths:
Glad it helped. I have also noticed that if I turn off wi-fi before plugging it in in again (after following this procedure), it appears to retain it's sleep ability.

If someone wanted to test an automated workaround, they could create a tasker (or macrodroid) task to turn off wi-fi when plugged in and then turn it back on when unplugged.

EDIT: I setup 2 macros in Macrodroid. One turns off wifi when plugged in and the other turns it back on when it is unplugged. Tested it briefly and both macros worked correctly. Better Battery Stats showed it still went into deep sleep, but I'll check it later today to verify it stayed in deep sleep.
[Galaxy Tab S2 Original Android Development] Krystanos:
The battery is draining quite fast even with the workaround. 2 days of idle time and the tablet is dead.

I don't know why your Macrodroid works. Since it reacts on plug/unplug, then the WiFi is disabled AFTER the tablet is plugged. Then it should have the same behavior when doing manually.

It means we should have the same behavior when disabling wifi juste before unplugging, and then reenable it just after. I'll try that.
[Galaxy Tab S2 Original Android Development] stroths:
I'll update my post after I verify if it stayed in deep sleep throughout the day after using the Macrodroid method. If it does, then my guess is something is activating at some point after the device realized it is charging and on wi-fi and the macro kicks in before that occurs. The macro turns off WiFi within a second of the device being plugged in.

UPDATE: I just checked and it stayed in deep sleep throughout the day using the macro I mentioned above. It does still drain faster than the stock ROM did, but I'll take the faster drain for the updated OS. Some of you with the no-sleep issue may want to give the macro method a try with either Tasker, Macrodroid or something similar.
[Galaxy Tab S2 Original Android Development] Krystanos:
I have installed addonsu and betterbatterystats to check. I left the tablet with 100% battery this morning, after charging while wifi on. I'll check tonight what I've got and see if it's the same as yours.
[Galaxy Tab S2 Original Android Development] Deltadroid:
You could also try this.
