Thank you!

If I backup using TWRP will it back up my lineage OS or the actual non rooted oem firmware of the device? I'd like to back up lineage as is with all data and settings...
[Galaxy Tab S2 Original Android Development] Turnilemikus:
If you're running Lineage OS, you've deleted your OEM version of Android. That's gone. Unless you're dual booting, of which I have no clue how/why.

TWRP can only backup your tablet as is; in our case that's Lineage OS. Root and all.

Practice up! You'll want a backup before you try Lineage 17.1. Which is what I'm currently using. A TWRP backup of Lineage OS 16 saved me a few hours
[Galaxy Tab S2 Original Android Development] pointbob:
thank u

It looks like the last update was on March 25th. Is this device no longer actively supported? I've been out of the scene for a bit so I'm not sure if I missed an announcement or something.
[Galaxy Tab S2 Original Android Development] sliding_billy:
Since it just had an update, I'd say it is still live. :D
[Galaxy Tab S2 Original Android Development] pWEN:
So there is! Glad this is still getting support!

I guess while I'm here, I'd like to report an issue I'm having with the fingerprint sensor. While on the lockscreen, the sensor doesn't seem to accurately read any of my fingerprints. Nine times out of ten, it says it's not recognized. I've gone into the settings and removed the fingerprints and was able to set up new ones just fine. It has better success after a reboot, but the longer I leave the tablet on, the less likely it'll work. I'm not sure what I can try to fix this, or if it's just a faulty sensor.
[Galaxy Tab S2 Original Android Development] lmacmil:
Looks like it's on a weekly update schedule. That's just the. At this point, I just want to stay current on Android security updates.
[Galaxy Tab S2 Original Android Development] lmacmil:
Are the Android monthly security patches incorporated automatically into the nightly builds? I just installed the 4/13 nightly and it still has the March patch.
[Galaxy Tab S2 Original Android Development] RoterfuX:
I'm on 4/20 and it's included
[Galaxy Tab S2 Original Android Development] WagaJr:
No clue what happen but I used the updater built in to update to the latest build and now im stuck in TWRP recovery (loop). I cleared cache/data to see if a factory reset would fix but nothing. I also tried to flash the ROM (original older build) again but it still just boots lineage than reboots back into TWRP.

Is anyone else using Amazon Prime Video App and has recognized, that HD resolution is not possible for any video neither via streaming nor download? Is this a general issue with LOS running Amazon Prime video?
[Galaxy Tab S2 Original Android Development] kryten4b:
Hi .. after completing latest upgrade from 4/20, my T713 drains battery totally overnight. Has anyone else seen this or have any workarounds? Thanks
[Galaxy Tab S2 Original Android Development] RoterfuX:
Yes same for me and I'm waiting for the next build
[Galaxy Tab S2 Original Android Development] takkischitt:
I've been using this ROM for quite a long time and I've always had issues with random restarts and WiFi connection issues. Does anyone else have these issues, or should I try and fresh install? Any other advice?
[Galaxy Tab S2 Original Android Development] lmacmil:
I had a random restart yesterday but that's rare, I can't remember the last time it happened. The wifi connection gets dropped about once a week and almost always requires a restart. I've had the wifi issue with every ROM including stock.

---------- Post added at 01:04 PM ---------- Previous post was at 01:01 PM ----------

Try putting it in airplane mode. I am on the 4/13 build and lose 1-2% overnight in airplane mode.
[Galaxy Tab S2 Original Android Development] Deltadroid:
The wifi connection issue seems to be fixed for me on cm-14.1 (Delta Nougat), but I made so many changes that I'm not exactly sure which one fixed it.
[Galaxy Tab S2 Original Android Development] lmacmil:
I was never on 14.1. I went from stock 7.0 to LOS 15. I would certainly never go back to fix this problem.
[Galaxy Tab S2 Original Android Development] lmacmil:
It's been a month since the last update. Are they done for good?
[Galaxy Tab S2 Original Android Development] sliding_billy:
There are a TON of changes to be included in next build (since lineage-16.0-20200420-nightly-gts28vewifi-signed.zip) according to the LOS downloads site. I can't imagine all of those commits would have been made if there was no intention of releasing an update. https://download.lineageos.org/gts28vewifi/changes/
[Galaxy Tab S2 Original Android Development] grmcdorman:
There was an intrusion of some sort to LOS servers around a month ago, if I recall correctly; the delay could also be related to that.
[Galaxy Tab S2 Original Android Development] morfeas-dsl-:
We hope for a great update as usual :)
[Galaxy Tab S2 Original Android Development] lmacmil:
I don't know how the updates get generated but I think that as the time since the last update gets larger, the likelihood of a new one gets smaller. I hope I'm wrong.
[Galaxy Tab S2 Original Android Development] :
I am afraid it's end of the road for this tablet. I hope to be wrong, but it doesn't look good.
[Galaxy Tab S2 Original Android Development] lmacmil:
Well, aside from liking to be current on the monthly security patches, it does everything I want a tablet to do. I'll stay on LOS 16 until 17 has more of the bugs ironed out. For my use, the 8" screen size is perfect.
[Galaxy Tab S2 Original Android Development] emperor8696:
The bluetooth keeps crashing on the first boot. I flashed the rom, gapps, magisk, and force encrypt disabler, all in that order. Has anybody encountered the same issue?
[Galaxy Tab S2 Original Android Development] RoterfuX:
Device is still supported and new updates should be available in the next days. The build servers were down for a while.

[Galaxy Tab S2 Original Android Development] lmacmil:
The June 1st build is online!
[Galaxy Tab S2 Original Android Development] lmacmil:
Who has installed the June build? Is it as stable as previous builds?
[Galaxy Tab S2 Original Android Development] sliding_billy:
I installed 0601 with Updater right after it posted. Despite the amount of commits in the build, I noticed no changes from 0420. It installed quickly and is working fine for me.
[Galaxy Tab S2 Original Android Development] lmacmil:
I installed it today and it's fine for me also.
[Galaxy Tab S2 Original Android Development] FSantillan:
Mic error

1st Thanks for the thread

2nd I apology for my bad english

So i performed a clean installation of lineage 16 from stock via odin and twrp, everything seems to work great, appearance and performance, but the mic gain is so so low, even if i yell directly to it, its remarkable low, there doesnt seem to be a difference wether im yelling or not to it, in any aplication (i tried two of them), btw the voice assistant seems to hear me fine, (i tried deactivating it but it makes no difference)

My device is SM-T713, i installed gapps pico, and addonsu 16 arm 64

If someone knows a fix that doesnt involve going back to stock im gonna be very thankful, maybe some easy fix, or an older version of lineage that works fine.

But if theres none, i also accept an easy explanation of how going back to stock, (i have no clue other than i need odin)

Its my first rom installation, so i'm not very experienced on this sorta things
[Galaxy Tab S2 Original Android Development] Deltadroid:
There are several different recording mixer paths. What specifically are you doing when the mic gain is low? Video recording? Skype call?
[Galaxy Tab S2 Original Android Development] FSantillan:
I tried with a zoom call, and the voice recorder
[Galaxy Tab S2 Original Android Development] Deltadroid:
Zoom and the voice recorder use different recording paths. Zoom uses SND_DEVICE_IN_SPEAKER_MIC and the voice recorder uses SND_DEVICE_IN_CAMCORDER_MIC (if you are not using a headset mic). My first guess is that this issue is within audio_platform_info_extcodec.xml. If you look at the history of that file, you can see that paths were changed around to increase the volume.

https://github.com/LineageOS/androi...e-16.0/audio/audio_platform_info_extcodec.xml

I don't have a T713 to test with, but that is where I would start. You can make changes to that file with a text editor w/o having to actually rebuild the ROM, if you want to experiment.
[Galaxy Tab S2 Original Android Development] FSantillan:
To find that file i need some root file explorer? or i need to plug it into computer?

Anyway, what should i look for to edit?
[Galaxy Tab S2 Original Android Development] Deltadroid:
This commit tried to increase the volume of video recordings by making SND_DEVICE_IN_CAMCORDER_MIC use the voip-main-mic-comm mixer path on acdb_id 61.

https://github.com/LineageOS/androi...8ad263e#diff-4092425a1ee1cd107fcb7a3509761305

This commit tried to use increase the volume of video recordings by making SND_DEVICE_IN_CAMCORDER_MIC use the rec-main-mic mixer path on acdb_id 4.

https://github.com/LineageOS/androi...09eb8cc#diff-4092425a1ee1cd107fcb7a3509761305

If you can find an audio mixer path and acdb_id that has a good volume, then you can try changing everything over to that mixer path and acdb_id. The history of the file might help.

The lines you care about are these:

https://github.com/LineageOS/androi...udio/audio_platform_info_extcodec.xml#L42-L48

https://github.com/LineageOS/androi...dio/audio_platform_info_extcodec.xml#L94-L108

You could try changing the mixer paths and acdb_id's of SND_DEVICE_IN_SPEAKER_MIC and SND_DEVICE_IN_CAMCORDER_MIC to previously used values or maybe a new mixer path and acdb_id that is/was already defined in the xml file.

The easiest way to edit this file (/vendor/etc/audio_platform_info_extcodec.xml) is to reboot into twrp and connect the device to a computer with an adb shell.
[Galaxy Tab S2 Original Android Development] takkischitt:
I just thought I'd update regarding this; I ended up doing a full reinstall and it seems to have fixed all the issues I was having (random restarts, WiFi disconnecting, etc). The tablet feels like a new device! Thanks for your help!
[Galaxy Tab S2 Original Android Development] ceanth:
Hi all,

I know I'm very late to the party but I picked up a T713 today!

I was that there was unofficial LOS17.1 support but I'm looking for something a bit stable so going to go with this ROM.

Planning on reading through all the posts but are there any issues in the current build? Planning on mainly using the tablet for Amazon Prime, Netflix and YouTube.

Thanks
[Galaxy Tab S2 Original Android Development] grmcdorman:
The current build seems pretty stable for me. I have, in the past, seen a boot loop where the tablet displays 'Tablet is rebooting', boots into the system, and then reboots. Have not seen it recently, but if you do get it the only solution is to hold power+home+volume down (or is it volume up? .. I forget) to boot into the loader, and then reboot into recovery and reboot the system (or power off) from there.
[Galaxy Tab S2 Original Android Development] ceanth:
Thanks, going to install it tonight.

An I able to go back to stock ROM and recovery pretty easily if needed? I remember that Samsung has Knox where you would trip it if you flash custom ROM, is this also applicable for this tablet?
[Galaxy Tab S2 Original Android Development] lmacmil:
I've been running LOS16 since it went official. Never had an issue. I usually update monthly when the new security patch gets incorporated. Running the June 15 build and it's fine.
[Galaxy Tab S2 Original Android Development] ceanth:
Thanks, I've installed LOS16, works really well.

I saw that there is a new nightly build, where can I see a change log for this? There is an option in settings to see change log but it takes me to a webpage that doesn't actually show any changes.

Actually tried again in a different browser and it works. Maybe not compatible with Opera browser, probably due to ad block

Updates to LOS I can flash with in built updater right?
[Galaxy Tab S2 Original Android Development] lmacmil:
That's the way I've always done it for the installed version.
[Galaxy Tab S2 Original Android Development] ceanth:
Hi all,

Running LOS 16 for a few days and I've noticed that the tablet speaker volume is quite low.

I've tried tweaking AudioFX to try and boost the volume, which it does not feel like it's enough.

Has anybody experienced something similar? Any other solution to increase the speaker volume?
[Galaxy Tab S2 Original Android Development] lmacmil:
Anyone able to cast to a Roku? The tablet says "invitation sent" but the Roku doesn't display. My Samsung TV doesn't even show up even though it's on the same network.
[Galaxy Tab S2 Original Android Development] justjeepin:
I'm running LOS16 on an unrooted T713 and it has been freezing and sluggish since February or March. If I do a factory reset will I have to reinstall LOS or does it just reset LOS like a fresh install?
[Galaxy Tab S2 Original Android Development] ceanth:
It will just reset LOS, no need to reinstall.

Maybe try flashing the latest nightly from the update menu
[Galaxy Tab S2 Original Android Development] justjeepin:
Thanks. I've flashed the latest twice since they restarted the downloads and no luck so far. I'll flash the most recent and then just reset.

On my computers and phones I usually do a clean install/reset once a year to keep things running smoothly. So I'll try it on the tablet.
[Galaxy Tab S2 Original Android Development] RoterfuX:
I think it started for me in the same time, but I'm not sure. I noticed that it restarts more often when It's below 30ish % and when I open Google Maps or websites that load loads of images. Let me know if the reinstall helps, maybe I'll give it a try too
[Galaxy Tab S2 Original Android Development] justjeepin:
So far it seems to have helped.
[Galaxy Tab S2 Original Android Development] friedsonjm:
Up and running....
[Galaxy Tab S2 Original Android Development] lmacmil:
Freezing seems to be happening more frequently lately and lasting longer. Sometimes I have to force a reboot. I'm running the second July build. I never let the charge drop below 40%. Can't remember when this started but it's definitely worse than it was a few months ago. I usually update once a month after the monthly security patch gets incorporated. Not ready to try 17 yet though.

[Galaxy Tab S2 Original Android Development] 2be3_80:
Which build are you currently running?
[Galaxy Tab S2 Original Android Development] friedsonjm:
9 pq3a.190801.002

That was an OTA update.

Maybe the 8/03 nightly? https://download.lineageos.org/gts28vewifi
[Galaxy Tab S2 Original Android Development] 2be3_80:
Are there any negatives of this rom or everything is running fine? Would you recommend it over stock one within standby time and screen on time?

Stock one in standby is really good - overnight it lost 0-1% battery.
[Galaxy Tab S2 Original Android Development] friedsonjm:
It is definitely smoother and faster than stock. I've not noticed any large battery drain, but I have not run a 'run-down' comparison between the two ROMs. I found stock to be very sluggish, and this is a huge improvement, and very stable. If you are rooted and have TWRP installed, you could always make a back up of stock, and revert if you don't like this ROM.
[Galaxy Tab S2 Original Android Development] lmacmil:
I typically see 3-5% overnight with wifi left on or 1-2% in airplane mode. The drain with wifi on seems to vary a little bit depending on the build. In airplane mode, it's pretty consistent. Having an up to date security patch is worth the small sacrifice in battery life for me.
[Galaxy Tab S2 Original Android Development] HungLu:
I tried unsuccessfully access OTG devices from Lineage OS 16. It sees the OTG devices but cannot play any video on the OTG devices (256GB flash drive and SSD 512GB). Also the battery get drain daily. Any suggestion. Thank you. My Galaxy S2 8.0 SM-T713.
[Galaxy Tab S2 Original Android Development] Dnorris55:
I am able to play video files (.Avi, .MP4, .mpg, .mov, .mkv) on my T713 via OTG. I tried 16GB, 64GB flash drives(exFAT) and 500GB SSD(NTFS). All worked ok. Tried a 250GB nvme in an enclosure, but it wouldn't list the files. Played all videos in VLC. Used Files app (or Settings - Storage) to list files then open with VLC.

Hello. The rom is great, everything is smooth BUT I am having huge battery drain when idle. I am talking about 4-6% per hour. Is there a way to fix that? I don't believe that any app is responsible.
[Galaxy Tab S2 Original Android Development] lmacmil:
Try Accubattery to see which apps are using battery. My battery drains about 1% per hour when idle. I put in airplane mode overnight and it loses 1-2% in 10 hours. Accubattery will also tell you if it's going into deep sleep or not. Mine is in deep sleep over 90% of the time when not in use.

Suddenly getting many random reboots. Five yesterday almost one after the other. Two while in Chrome and three while in Instagram. One so far today while in Weatherbug. Going to try a newer build. Currently o the 9/14 build.
[Galaxy Tab S2 Original Android Development] westwolf007:
Great ROM.

I've been using it for couple of years. I have noticed any problems except GPS never worked. It's my home tablet, so didn't really bother me.

Anyway, does anyone have the same issue or any known solutions?

Thanks.
[Galaxy Tab S2 Original Android Development] lmacmil:
When you say the GPS never worked do you mean it won't detect your location? If so, have not had that problem.
[Galaxy Tab S2 Original Android Development] westwolf007:
Correct. No location data from GPS. Only approximate location from WIFI scanning.
[Galaxy Tab S2 Original Android Development] :
+1

Since I installed the latest build I have been getting random reboots, especially when trying to watch videos in Chrome (e.g. news outlets). This is not new - I had that a few times in the past - but now it happens much more often. By the way, the problem is not reproducible: if I try to do again what caused a spontaneous reboot, the second time nothing happens.
[Galaxy Tab S2 Original Android Development] Kenshinhimora:
I cannot connect to a WPA-2 enterprise wifi because there is no system cert on the device. Has anyone run into this? The connect button is essentially grayed out.

[Galaxy Tab S2 Original Android Development] friedsonjm:
One problem I continually have with my 713 is that it 'loses' wifi connection. This typically happens when it is left unused for an hour or two. Automatic reconnect is turned on. I have to turn wifi off and on again for it to reconnect. Is there an app or any other kind of fix available?
[Galaxy Tab S2 Original Android Development] lmacmil:
I think it's a hardware issue. I've had the same problem with stock Android 7 plus Lineage 15 and 16. Sometimes I have to reboot to get the wifi connection back. When the connection drops and reconnects on its own, I wonder if it's my router.
[Galaxy Tab S2 Original Android Development] friedsonjm:
I have three wifi networks running, and it could access any of them. One range extender is only a few feet from where it sits. Still shuts wifi off. It may be a hardware issue, but not with the routers.

[Galaxy Tab S2 Original Android Development] lmacmil:
I'm on a November build. The front camera works fine but I haven't used on a video call. I did open Skype and took a picture of myself so it's ok with that app.
[Galaxy Tab S2 Original Android Development] solnyshok:
I tried LOS17.1 yesterday, but it is too raw (bluetooth, sdcard, camera issues). and I finally settled on this ROM. it is officially amazing! Everything works. Smooth and fast. Lean and mean. bluetooth aptx hd and wireless controllers (SonyDS4) work, cameras work, no problems with sd card.
[Galaxy Tab S2 Original Android Development] lmacmil:
This is what I have inferred from reading the posts in the 17.1 thread. Many seem satisfied with 17.1 but 16 is working fine for me so I'll stick with it for the time being.
[Galaxy Tab S2 Original Android Development] lmacmil:
I'm still on TWRP 3.3.1-0. I update LOS 16 once a month after the latest security patch gets Incorporated. I have not had any issues using the built-in update process. Any reason for me to update TWRP to the latest version?
