Same here getting horrible battery life!
[Galaxy Tab S2 Original Android Development] isimobile:
Battery drain test: I have disabled WiFi, and left my tablet for 24 hours, see attached screenshot, it still is awake,no deep sleep.

I noticed that it seems that Google play services is keeping it awake. It seems that the "Significant motion sensor" is keeping it awake, or am I misinterpreting it? Maybe something to look into? I have bbs Stats saved if you want to look into it?

Not sure if it helps?

Do you have on body detection turned on? Have you tried doze on the go?

Installed 15.1 a couple of days ago on a brand new T713.

This thing is amazing. The difference in responsiveness is amazing, feels like a modern tablet again!

Fingerprint sensor is slightly worse than stock, but nothing I can't live without.

Tablet does not sleep properly. Even in airplane mode, battery will be dead within 2 days.

But these are minor issues. The device is so much faster I don't care. Still the best tablet on the market for me. Great size, amazing weight, excellent screen :)
[Galaxy Tab S2 Original Android Development] :
I got Better Battery Stats and did some testing. In short, every time I notice an unusual battery drain (i.e. the tablet doesn't go to sleep) I see that "ueventd" has been using by far most battery. Whether WiFi is on or off does not seem to affect the occurrence of this issue. A reboot usually clears this for a while, typically until I charge the tablet again.

I have other devices running LOS 15.1 and this is the only one showing this problem, by the way.

Anybody else audio get choppy after the last update. Or is there something going wrong with my tablet
[Galaxy Tab S2 Original Android Development] Miggles:
My audio has been choppy for a while now, since nobody else was mentioning it I figured I had managed to mess my tablet up. It's quite a relief for me that you've brought this up.
[Galaxy Tab S2 Original Android Development] rionline:
Is there an easy way to switch to T713 linage rom with my T719 device? I assume that i would only loose my cellular option, which i do not mind at all. This way i could use OTAs and enjoy official support.
[Galaxy Tab S2 Original Android Development] brightjh01:
I don't know what got my not working, But I reinstalled with clean install and it works fine now. :good:
[Galaxy Tab S2 Original Android Development] busdonic:
I too also had this problem after the last update. I tried restoring a prior install with no change--still skipping. After deleting apps, rechecking source files and then realizing it was also happening on YouTube, I made the big move to reinstall with a clean install and audio is back to normal now.
[Galaxy Tab S2 Original Android Development] Krystanos:
I confirm the battery drain issue, even with latest ROM update. It's been happening since june, after a handful of ROM without battery issues, following ROM with battery issues... Not sure this is the same issue, but when not being used, the tablet runs out of juice after 1-2 days..

I don't know if there's something to be done, it seems the thread is not being followed anymore by the maintainers.

However, if it's not the case, I could do some tests to help the analysis. Just tell me what kind of test need to be done :)
[Galaxy Tab S2 Original Android Development] Ssea:
Hi, LuK1337. Could you add bootloader version T713ZCU2BRF4 as supported? I purchased a T713 this week and updated it to the latest stock rom. It's probably the latest bootloader version. Thanks!
[Galaxy Tab S2 Original Android Development] nostupidthing:
x2
[Galaxy Tab S2 Original Android Development] gorthon:
Battery drain here confirmed as well.
[Galaxy Tab S2 Original Android Development] knoxjon:
I am also seeing very little deep sleep in the last build. If anybody finds a fix or a better ROM, please let us know!
[Galaxy Tab S2 Original Android Development] lmacmil:
Installed today and reloaded all my apps. So far, so good. I was surprised at the speed of the first boot, less than 5 minutes, a lot shorter than previous LOS installs I've done on other devices.

After about 16 hours of uptime, AccuBattery reports the tablet was in deep sleep for 91% of screen off time. That seems pretty good to me. I'm on the 10/01 build.
[Galaxy Tab S2 Original Android Development] gorthon:
This value reported by AccuBattery doesn't seem to be related to the issue: I have the same here, even 98% deep sleep, but still I lose about 20% battery in a day without ever touching the tablet.

Can anyone point me to a version where this problem doesn't exist yet? I would rather stay on an older version until this is fixed. Going back to stock is such a hassle.
[Galaxy Tab S2 Original Android Development] god_md5:
i not have this problem , over 11 hour ,is 100%
[Galaxy Tab S2 Original Android Development] gorthon:
Did you also have the most recent stock firmware before, or do you already have LOS for some time? What's your bootloader version?

I went back to stock now and the problem is gone (5% over 24 hours, instead of 15 to 20%)
[Galaxy Tab S2 Original Android Development] god_md5:
This firmwae?
[Galaxy Tab S2 Original Android Development] god_md5:
100%
[Galaxy Tab S2 Original Android Development] lmacmil:
Curious if people install every nightly update or do stick with whatever version you are on if aren't having problems. I flashed the 10/01 nightly about 10 days ago, having been on stock Nougat since buying the 713 almost 2 years ago. Have only had a couple minor glitches which did not reoccur. I'm inclined to stay where I am unless there's a compelling reason to switch.
[Galaxy Tab S2 Original Android Development] gorthon:
No, this one:

[Galaxy Tab S2 Original Android Development] gorthon:
Guys, the battery problem is reported here and the maintainer is willing to debug. I can't get a hold of the tablet anymore, as it's not mine, to do such experiments. Could maybe one of you who also has the battery drain issue report back if it also happens with a fresh clean install of LOS?
[Galaxy Tab S2 Original Android Development] lmacmil:
I experienced the "wifi bug" today for the first time since flashing 15.1. Everything was fine and suddenly pages wouldn't load. After a minute or so, the status bar wifi icon went from filled in to empty. When I turned wifi off and back on, it said no networks were available so I had to reboot to restore the connection. This is slightly different behavior than I experienced with stock Nougat. With the stock ROM, if I lost the connection and turned wifi off, it would not turn back on at all. In both cases, a reboot solved the problem. Not a big deal for me.
[Galaxy Tab S2 Original Android Development] god_md5:
can get a Project Treble ver?
[Galaxy Tab S2 Original Android Development] LuK1337:
What's the point of wasting time on that? We don't even have /vendor partition to begin with.
[Galaxy Tab S2 Original Android Development] god_md5:
i know this ,but can make a /vendor partition .file only copy the /system/vendor? and a twrp Treble?

https://xdaforums.com/axon-7/development/tool-party-v0-1-vendor-partition-t3831517/page11

3.4 Q: What is the vendor.img/vendor.zip? (5X and 6P only)

3.4 A: The vendor partition is new to Nexus phones with the 5X and 6P. Previous devices had the vendor files (proprietary binaries and drivers) within the system partition (/system/vendor); on these devices, they now have it in their own partition (/vendor). If this is not up to date, you will get an error message and need to flash the latest one so your phone continues to work properly. Beans has made this a TWRP flashable file available in the OP of the 5X and 6P threads (also linked below) so you do not have to fastboot it.

man, this rom is amazing. it made me enjoy using my tablet again. stock samsung OS that was like android 7 was horrible and slow. This made it feel like a whole new device.
[Galaxy Tab S2 Original Android Development] lmacmil:
Tried to cast to my Samsung TV today but all the tablet sees is my Chromecast Audio. I have cast to the TV under stock Nougat without a problem. Didn't see anyway to refresh the device list. Suggestions?
[Galaxy Tab S2 Original Android Development] J_M_H:
Anybody having trouble with the builds after 11/6? The new builds cause my device to slow down dramatically. Thanks.

I am on the 10/01 build. Last night I charged it accidentally to 100%. After 11 hours with no usage and wifi off, it was still 100%.

How/where can I download this build (10/01) as the official download link only shows recent builds
[Galaxy Tab S2 Original Android Development] woundedworld:
I would too like to know where I can get this build as I just purchased a T713. Thanks in advance!
[Galaxy Tab S2 Original Android Development] brightjh01:

thanks a bunch for building this ROM!!

I'm not seeing my 5Ghz network but am seeing 2.4Ghz of same network router

It's an ASUS TM-AC1900

But I am seeing 5Ghz on neighbors router

Just installed Sept 22 build on my new tablet:

[Galaxy Tab S2 Original Android Development] nostupidthing:
Configured your country?
[Galaxy Tab S2 Original Android Development] BackCheck:
I don't know if it's related but both the T713 and T813 seem to have an issue with the upper bands of the 5ghz in the Official 14.1. I know at least on my T813 that it is set for the correct country.
[Galaxy Tab S2 Original Android Development] 360Razir:
I just did a clean install of 9/22 build and my 5GHz is picking up just fine.

---------- Post added at 06:35 PM ---------- Previous post was at 06:32 PM ----------

First time since owning my Tab S2 (about 6 months) that I've had SMS working via Hangouts AND video playback at the same time. Truly impressed by the 9/22 build thus far. Thanks and donation sent.
[Galaxy Tab S2 Original Android Development] BackCheck:
What channel? The lower channels work, upper channels seem to work. I haven't managed to pinpoint the cutoff since I'm not at home where I have multiple WAPs on that freq.
[Galaxy Tab S2 Original Android Development] Jadog:
So is root not possible with this version?
[Galaxy Tab S2 Original Android Development] LuK1337:
Addon-su won't work but you can use other root options like SuperSU at your own risk. I won't be supporting that by any means.
[Galaxy Tab S2 Original Android Development] Jadog:
This might be a dumb question, but what exactly is the difference between the two? Don't they both provide root access?
[Galaxy Tab S2 Original Android Development] LuK1337:
Yes, but SuperSU is closed source and doesn't integrate into OS the way addon-su would.
[Galaxy Tab S2 Original Android Development] Jadog:
Interesting. So after further research, the main benefit appears to be that addon-su will allow future LineageOS updates without loosing root. If installing SuperSU, then it will have to be re-rooted (installed again) after each LineageOS update. Maybe Magisk could provide similar benefit as addonSU?
[Galaxy Tab S2 Original Android Development] Sgace:
Saw there was an updated build, thnx for that!

Does it already include the wifi fix?

[Galaxy Tab S2 Original Android Development] j555:
Thank you for giving us Oreo on this tablet. For the most part everything is working well. However I am seeing an issue with Bluetooth. Is anyone seeing issues with Bluetooth? It seems to crash on startup and then I can't toggle it on after that. If this is not a known problem let me know and I can get a log and post it later.
[Galaxy Tab S2 Original Android Development] LuK1337:
Yeah it's broken, I'll release updated build later today. Thanks for reporting it.

Do i must root to install the custom recovery to flash this Rom when coming from stock firmware Thank you.
[Galaxy Tab S2 Original Android Development] Lupin The Third:
No. Flash twrp with odin.
[Galaxy Tab S2 Original Android Development] guinnes.s:
Thanx

Anything I should know regarding using twrp for backing and restoring current stock firmware later on just in case?

What to clean before flashing ROM ,?

Sorry for so many questions,been away quite a while from the flashing ROM community.

Thanx again
[Galaxy Tab S2 Original Android Development] Lupin The Third:
You cannot use twrp to backup data on stock rom. You have to remove encription first from stock rom by formating (not wiping, formating) data. This, obviously will delete all your data, so you have to save your data somewhere. After that you can use twrp to backup stock rom.

And to flash new rom wipe everything, system, caches and data,
[Galaxy Tab S2 Original Android Development] apokit:
You will keep updating this rom....dont you?

Because its fantastic

Nov 26 build is great

Hello everyone, first post here on XDA.

I recently bought a T713 and I am currently running the nightly from November 26. I don't use my device for calendar, email or any other sync, so I guess I could be a good candidate for good results on deep sleep. I just use it for web, series, movies, games, tuning my instruments, etc... Basically only "screen on" features (my phone already needs to connect on a permanent basis so I say let him do all the sync stuff). I have a simple tasker profile turning off wifi a few minutes after screen off in case I forget to turn it off manually, and a trivial home screen widget to disable this profile in case I'm downloading stuff or if I need "screen off" wifi for any other reason.

This being said, I can say I have perfect "screen off" battery life with this awesome ROM (minus 0% for more than 24h). So I don't understand why you guys need to get your hands on a previous build just because one guy said it was better then. My (short) experience tells me I could hardly get a better battery life than the one I currently have on the Nov 26 build. My feeling is, if you have battery issues, your post Nov 10 build might not be the root cause...

So big thanks for Luk1337 for providing this quality OS to us! I'm thoroughly enjoying it. Flashing this Nov 26 build alongside the pico gapps makes my T713 light, fast and stable.

Actually, I have only one minor issue that I don't understand. It is about gaming performance, and I don't know if it's a known issue, or if it's just something I have to tweak so it can behave properly.

I tested XCOM Enemy Unknown with my stock device fresh out of the box, and the intro cutscene played flawlessly. Now, everytime (100% reproducible even after fresh boot) it stutters a bit, and then halts completely for more than 30 seconds (although the audio keeps going). It doesn't keep me from playing since the interactive part is quite ok, but this is the only time I could clearly see something that is better with stock OS, so I was wondering why...

However, even with this minor issue, I can testify that the post Nov 10 builds have no battery issue. I was sad for Luk reading these posts and this is why, after years of silently using XDA knowledge, I felt I had to say it!
[Galaxy Tab S2 Original Android Development] nigeldr:
This is the best advice that I've seen and implemented straight away, can immediately see the improvement today. Thanks

comming from 5.02 ?

Hi, I did not flash any rom on my tab s2 for ages as I didnt want to loose one of my apps (every time new rom was flashed app devs would count it as new device and I only could use 3 :( )

...so I am coming from 5.0.2, is it safe / OK to just flash it as per first comment instructions?

Instructions :

Download the latest build and gapps

Reboot to recovery

Flash the latest build and gapps

Reboot

thanks!

I updated from the 10/01 build to the 12/7 build using the Lineage updater. It worked fine. Battery life is very good and unchanged from the earlier build.
[Galaxy Tab S2 Original Android Development] sketchman16:
Just installed the latest. Seems fine so far.

I guess we have just given up getting local videos to play correctly? It's really the only thing I've missed, but seems like it's never getting fixed.

I could post logs if there's actually a reason to.
[Galaxy Tab S2 Original Android Development] lmacmil:
What do you mean by "local videos"?
[Galaxy Tab S2 Original Android Development] sketchman16:
Video files stored on the tablet. YouTube/Netflix/etc. works fine, but if I have an app that DLs a video and then tries to play it the video freezes repeatedly while the audio still plays. This has always been an issue. It was mentioned a few times but never got fixed.
[Galaxy Tab S2 Original Android Development] lmacmil:
I have a couple videos that I took with my phone and downloaded to my tablet. They play fine. Are certain types of video formats that are affected?
[Galaxy Tab S2 Original Android Development] sketchman16:
Not really sure what the specifics are, but I know it was both mp4 and mkv, which I know is not helpful info on its own. It was both high res and low res stuff. I'll grab some info and post it.
[Galaxy Tab S2 Original Android Development] LuK1337:
Yeah I'm watching my chinese cartoons /w mx player just fine. Try flashing newer firmware lol.
[Galaxy Tab S2 Original Android Development] sketchman16:
You mean newer stock FW and then back to LOS? I'd be willing to do that, but I never imagined that would help.
[Galaxy Tab S2 Original Android Development] LuK1337:
If you're smart enough to use heimdall you can just flash everything but system, boot, cache, userdata.

$ heimdall flash --SBL1 sbl1.mbn --ABOOT aboot.mbn --RPM rpm.mbn --TZ tz.mbn --HYP hyp.mbn --SEC sec.dat --KEYMASTER keymaster.mbn --CMNLIB cmnlib.mbn --DSP adspso.bin --MODEM modem.bin --APNHLOS NON-HLOS.bin --HIDDEN hidden.img.ext4
[Galaxy Tab S2 Original Android Development] sketchman16:
Soooo, I did that, successfully, but the issue persists. Happens regardless of which media player I use or what video I try to play. And I've attached a log.

This seems to be a super repeated thing. Maybe it shows what the issue is?

[Galaxy Tab S2 Original Android Development] sketchman16:
Hmm. So you mean a clean install and no using Titanium Backup? I'm sure that could make sense, but this tablet was setup fresh, because I lost my last one, and I couldn't use TB to restore things. I've also never run stock FW on this tab. It was setup fresh with LOS 14.1, and the issue has been there since the beginning.

I guess it's worth a shot. I'll do a TWRP backup, move it off the tab, start fresh, and report back.

Just to make sure I understand though, you're saying install full stock, wipe, and setup fresh with a clean install of LOS and no app restore?

EDIT: So, a clean install of stock FW does not show the issue. Gonna flash LOS and see if videos still work correctly.

EDIT: OK. I'm totally baffled. Clean stock Samsung FW plays videos fine, but a clean LOS with 0 apps installed videos stutter every single time, and right now I'm going on flash #3 trying different combos of things. This is insane.
[Galaxy Tab S2 Original Android Development] sketchman16:
I'm done. Would be nice to play videos, but it's not gonna happen, apparently. I had a phone like this once. LG 4x HD. Refused to work properly on ANY custom ROM, but was perfect on stock, outdated FW. Seems like this tab has a similar issue, and I'm done trying random crap to make it work.

If anyone has any ideas, I'll still gladly try them, but I don't have anymore. Netflix/YouTube/etc still works.
[Galaxy Tab S2 Original Android Development] SunJu22:
This is really strange. All my video files stored locally (mp4 & mkv) play fine with VLC. I only have the issue in games (XCOM Enemy Within, as I said, and also - I just found out - Road Not Taken).

Does anyone know how I can find the video files of these intro movies? I would like to check their format, size, and any other properties that may help identify the root cause of the issue. I would like to compare this data to the same data in some other games where the intro movies play fine.
[Galaxy Tab S2 Original Android Development] sketchman16:
Took one more shot at it, and guess what? VLC plays videos just fine. Not sure if that helps, and it makes 0 sense to me, because I even went through VLC settings and messed with everything to try to make it play videos badly, hoping to see what is causing other players to not work, and I discovered nothing.

It just works, and every other player doesn't, and I have no idea what that means.
