[Galaxy Tab S2 Original Android Development] T_I:
Other then that the sources are coming from LineageOS github, nop. At least there are no changes in my sources, some in LineageOS sources, but I didn't notice any differences.

This was a test build to see if all was transferred correctly.
[Galaxy Tab S2 Original Android Development] xeta_at:
Ok.

Then I will wait for the next Update.

Except the mentioned problems the ROM already works fine for me.

Hi,

Have Problems with YouTube (Videos Looks after 30sec in Zoom) and Facebook Videos are Not starting.

[Galaxy Tab S2 Original Android Development] Katzenstreu:
I think, I'll give it a try. Actually I'm using [ROM 5.0.2] [Kernel] [Mod] Tab S2 [T715-T715Y] v3.0 By Jafangie|Deodexed|Rooted . But there are still some issues, like failure "Gallery stopped".

Best regards

Tim
[Galaxy Tab S2 Original Android Development] nostupidthing:
Same in T710 but it's random, I mean the YouTube problems
[Galaxy Tab S2 Original Android Development] eliasps:
Great work, but this was built for the 10'' model. The screen size of the rom needs adjustment to fit exactly for this model. Other than that, once the important issues get resolved, this is my preferred ROM for my Tab S2. Already installed.
[Galaxy Tab S2 Original Android Development] Katzenstreu:
You can try to set 700 instead of 768 dpi.
[Galaxy Tab S2 Original Android Development] Katzenstreu:
Yes, the camera isn't working.

In the upper tiles I found a button for the torch. The tablet hasn't a torch.
[Galaxy Tab S2 Original Android Development] Katzenstreu:

[Galaxy Tab S2 Original Android Development] Giuskiller:
I use the fingerprint sensor a lot, maybe if this will be fixed i'll try the rom. I've heard about 7.1 coming for some 9.7" Tab S2 variant...not sure if 8" version will receive it too. But i didn't hope. Samsung teached me how to kill a device without major updates with my previous device.
[Galaxy Tab S2 Original Android Development] T_I:
Lineage 14.1 is Android 7.1, so yeah, it'll be there for T715. Fingerprint sensor isn't working on any Samsung device (at least on any Tab S2, 2015 or 2016 release). This is being worked on, at least for all Samsung Exynos devices. (common lib)
[Galaxy Tab S2 Original Android Development] Giuskiller:
Yeah i know that Lineage OS is Android 7.1, but i was talking about official one by Samsung. I've heard it's coming for some Tab S2 9" variants but it's not sure if it will be avaible for 8" models too. Anyway, hope that the fingerprint will be fixed soon :) thaks for all the work you do guys
[Galaxy Tab S2 Original Android Development] Sir2k17:
Hello and a big thank for your work so far. I gave it a try (2017-02-06 build) and liked it very much. Despite the camera problem I encountered a strange behaviour when receiving the first call: I was able to pick up but couldn't hear anything. Then I tried to analyse the issue the behaviour changed - no incoming calls were possible. When I called someone from my mobile they could pick up the call but audio wasn't working. I couldn't hear anything and was not heard. Mobile data worked like a charm over LTE. Do you have an idea how and if this could be fixed? I would like to use Lineage OS as productive OS on my T715 and yes - I am using it for making phonecalls although it might look funny to see me with an 8" device attached to my head. I didn't try if audio would work with a BT device, but maybe I can test this on this WE. For now I'm stuck with stock rom again.

Thanks & Regards, Simon
[Galaxy Tab S2 Original Android Development] T_I:
As I just have a T710 on loan, I can't test RIL and call related issues. Mic should have been fixed, but I'm not sure.

As hardware libs were rewrittento change back to Samsung ril instead of the AOSP one, I had to copy a few gts210ltexx patches to gts28ltexx. I just did a recompile and uploaded the image. OP is updated. Haven't tested it. (I don't own a T715 and haven't had time to test if it'll boot on the T710)
[Galaxy Tab S2 Original Android Development] Sir2k17:
Hello, thank you for the new build. I gave it a quick try, but unfortunately the SIM module didn't recognise my installed SIM card. I tried shut downs etc. So telephony is broken :(. I rolled back to stock immediately and it worked again.
[Galaxy Tab S2 Original Android Development] Philippovitsch:
Same problem with fresh compiled build from my sources.

What I've read so far that's also an issue for T815 a the moment (there where some changes in the sepolicy for modem/ RIL recently, before that I didn't have any problems), so we have to wait for a patch for that ;)
[Galaxy Tab S2 Original Android Development] Katzenstreu:
Hello T_I,

the headphone jack isn't working too :(.

best regards

Tim
[Galaxy Tab S2 Original Android Development] T_I:
Hmmm, must be an 8" specific then... drowning in work at the moment, killing off my dev time. :(

Sent from my SM-T813 running L1ghtning 6.0
[Galaxy Tab S2 Original Android Development] Sir2k17:
No problem. Everybody knows this. I happened to start trying to build the rom myself but had only time to synch the Lineage 14.1 repository...this was a week ago. Didn't have time to continue...
[Galaxy Tab S2 Original Android Development] T_I:
RL is being hogging time like there is more then enough. :(

Uploaded build of yesterday (patch level march 5th). Updated OP. Image for T710 tested and boots. Camera still b0rken, sensor is there, but can't be used. I'm suspecting camera server, not sure.
[Galaxy Tab S2 Original Android Development] Sir2k17:
Thanks for the new build! I'm currently using it in daily routine. The problems are still present, but I have a dirty workaround... Using my lumia 930 for Photos, messaging and telephony. I didn't test the headphone yet. Hoping that the Sim might be recognised soon.
[Galaxy Tab S2 Original Android Development] donky kong 017:
Just to give my feedback. Most of the things (and probably more than I have tested) were said before. Running latest build

Vibration did not work, as did camera sensors. Sim module is broken and that drained my battery because of cell standby that I had to roll back to stock tw. Can confirm Fingerprint not working. Did not test BT or headphonejack.

Beside that, it's buttery smooth, snappy as hell. Almost a daily driver for me.

Thanks for the great efforts and keep up the good work.
[Galaxy Tab S2 Original Android Development] Philippovitsch:
I was able to fix vibration issue - did some changes in the kernel config. Sim Module is working fine for me after the first reboot. I'm playing around with some changes in the blobs right now (new BT-Firmware and patches from gts210 for GPS and RIL-related blobs). Will test that later today.

I also tried some solutions (without success yet) for the camera and found out that we are missing some files, which 've been removed by updating to Nougat (https://review.lineageos.org/#/c/160694/) - don't know what causes this issue.
[Galaxy Tab S2 Original Android Development] derpflo:
Can confirm, have the same problems / experience. All in all it's running very good for my use case. Just to confirm: lineage-14.1-20170321-nightly-gts28vewifi won't work with the SM-T715, right?

Waiting eagerly for the next build :)
[Galaxy Tab S2 Original Android Development] nostupidthing:
yes, "ve" (=value edition) uses snapdragon and has t713/t718 model no
[Galaxy Tab S2 Original Android Development] T_I:
Could you upload the patch via gerrit to LineageOS spurces, so they can be tested for T710 and added correctly?

Check, the VE version has a different CPI. It's possible to use the gts28wifi sources, when you don't mind loosing the lte module.

I've been way to busy with RL, killing my dev time. Have found some time to check a few suggested patches. Building now for gts28wifi. When confirmed that it's working there, I'll compile a gts28ltexx build.
[Galaxy Tab S2 Original Android Development] Philippovitsch:
I will give it a try in the evening, as I'm not familiar with gerrit yet.

You can already have a look at the changes as I uploded them to Git:

https://github.com/Philippovitsch/android_kernel_samsung_gts2_arch_arm_configs/commits/cm-14.1

This one fixed the vibration:

[U]CONFIG_MOTOR_DRV_ISA1000A=y
CONFIG_MOTOR_DRV_ISA1000A_WITH_MOTOR_EN=y
# CONFIG_SKIP_MOTOR_REGULATOR_CONTROL is not set[/U]
# CONFIG_MOTOR_DRV_ISA1200 is not set
# CONFIG_MOTOR_DRV_ISA1400 is not set
# CONFIG_HAPTIC_ISA1200 is not set
# CONFIG_HAPTIC_ISA1400 is not set
[U]# CONFIG_MOTOR_BLDC is not set[/U]

I compared the stock and Lineage kernel configs from T715 and T81x and adjusted them due to some mismatches, now there are just the "size/ model related" differences in my kernel konfig.
[Galaxy Tab S2 Original Android Development] T_I:
Thanks, I've included at least this fix in the kernel and I'm now recompiling. I already uploaded an image with a load of ril patches that were done to gts210ltexx because some changes in gts2-common and blobs. Updated OP and added link there to the 'pre kernel fix' image.

Vibrate patch added, doesn't seem to work in 710 though. Will update OP with link to latest build.
[Galaxy Tab S2 Original Android Development] T_I:
Ok, can someone test RIL to confirm that the patches I added (from gts210ltexx) result in a working lte modem on this device. Other patches have already been tested on wifi model.
[Galaxy Tab S2 Original Android Development] derpflo:
Hi, thank you for the new build. I didn't have the chance to test LTE yet but I can confirm that the vibration module is now working on the T715 :)

Unfortunately the headphone jack is still not working :/ I hope you can find a fix for that soon :)

Edit: LTE works on the T715 :)
[Galaxy Tab S2 Original Android Development] lucky_0815:
Tested and working

Hi,

i just installed the new build (20170416) and i confirm, that lte is working on my device.

Thanks, great work!
[Galaxy Tab S2 Original Android Development] T_I:
Sorry for being quiet for such a long time. I'm fine, just being locked in office, disabeling my development options. (and outside office hours RL was getting in the way)

The switch to N blobs killed BT and external SDcard. For the SDCard there was a fix uploaded and that works. BT is still broken, same as camera and it looks like adaptive brightness is broken as well. Updated OP.
[Galaxy Tab S2 Original Android Development] gammelobst:
Hi,

LTE is working a lot better now, thanks and keep up the good work...

[Galaxy Tab S2 Original Android Development] T_I:
Did a recompile, adaptive brightness seems to work on T710. (need to do further testing)

Updated OP.
[Galaxy Tab S2 Original Android Development] T_I:
Recompiled 16th with latest june security patches. Updated OP (will do recompile with latest patches from [MENTION=3463426]RaymanFX[/MENTION] tonight)

Edit: as promised, recompile with common patches. Updates OP again.
[Galaxy Tab S2 Original Android Development] T_I:
Did a recompile and uploaded image. Updated OP.

The T710 loaner is going back tomorrow. However, I found an T710 on ebay that was within price range (used donations + a bit of my own cash). With some luck it's in this weekend, so I can continue to develop. (want to get the image working correctly)
[Galaxy Tab S2 Original Android Development] T_I:
Did a recompile for latest security patches (july 5th), updated OP.
[Galaxy Tab S2 Original Android Development] Snilmerg:
Hi T_I, thanks for the great work !

I installed this build : lineage-14.1-20170708-UNOFFICIAL-gts28ltexx.zip from https://www.androidfilehost.com/?w=files&flid=148594

Developer here. I suppose I could setup an environment to build your image from the source and test things.

I have a T715. How can I help ?
[Galaxy Tab S2 Original Android Development] T_I:
Did a recompile to get the latest patches in (updated OP). Still hunting down the camera. Compiling exynos camera libs results in no camera what so ever. (But at least I have code to dive into) BT seems to be working again. Must have been an upstream patch. (can't take the crediit for it)

[MENTION=5644343]Snilmerg[/MENTION] Biggest issue I haven't solved are the cameras (device reports 0 available, but it has access to the correct sensors) and automated brightness. Could use some help with those.
[Galaxy Tab S2 Original Android Development] Snilmerg:
Hello,

I'm entirely new to Android ROM building. If anyone has tutorial / documentation / reference to point me to, I would greatly appreciate it.

I have followed this tutorial here :

http://www.lineageosrom.com/2017/01/how-to-build-lineageos-rom-for-any.html / https://xdaforums.com/chef-central/android/how-to-build-lineageos-14-1-t3551484

Which seems to work, but I get stuck at step "Prepare the device-specific code" (I used "gts28ltexx" as "DEVICE"):

$ source build/envsetup.sh
$ breakfast DEVICE

It seems to find the right repo (https://github.com/LineageOS/android_device_samsung_gts28ltexx), but dies with error "Don't have a product spec for lineage_gts28ltexx".

See log :

https://pastebin.com/U0i5FrSc
[Galaxy Tab S2 Original Android Development] Philippovitsch:
Looks like you are missing the vendor blobs:

You need to have this two folders included in your source in (/android)/vendor/samsung/

https://github.com/TheMuppets/proprietary_vendor_samsung/tree/cm-14.1/gts2-common

https://github.com/TheMuppets/proprietary_vendor_samsung/tree/cm-14.1/gts28ltexx
[Galaxy Tab S2 Original Android Development] Snilmerg:
Thanks for the hint ! Actually I think I was also missing the step where I must get the vendor blobs in (/android/system)/device/samsung/ by calling extract-files.sh in each of subdirs gts2-common and gts28ltexx.

I have a question. I made my environment starting with repo init -u https://github.com/LineageOS/android.git -b cm-14.1, then breakfast gts28ltexx, which pulls the repository https://github.com/LineageOS/android_device_samsung_gts28ltexx... which has its latest commit in april... so I guess this isn't the repository with latest changes by T_I ? Or should I pull patches from somewhere ?

I noticed these repo, https://github.com/Galaxy-Tab-S2/, might be more up to date ?
[Galaxy Tab S2 Original Android Development] Philippovitsch:
No, the link where you pulled your source code is the official one where [MENTION=4557146]T_I[/MENTION] loads up the latest changes. This one is good to go.

The Galaxy Tab S2 Developer Organization was the plattform, where changes where pushed before it went "official", they are outdated ;).
[Galaxy Tab S2 Original Android Development] Snilmerg:
Got it. Thanks for your help.

I'll dive in all of this during the week. Little chance I'll even begin to have a clue on how things work, before you guys have all of it fixed, but, heh, at least I'll learn stuff in the process ^^ And who know, n00b luck ^^
[Galaxy Tab S2 Original Android Development] Philippovitsch:
You're welcome! Congrats!! ;)
[Galaxy Tab S2 Original Android Development] T_I:
New build uploaded, no fixes, just a buil;d with the latest security patches. (patch set of 5 august)

Updated OP.
[Galaxy Tab S2 Original Android Development] Snilmerg:
Great, thanks !

(I hadn't activated email notifications, I didn't see your post until today, I'll try this latest build soon).

No progress from me so far. Reading books on Android Architecture and Linux Kernel ^^'

Since my last post I have been testing the image I had built, which runs just fine except for few problems :

Camera not working (we already knew that)

Automatic brightness not working (we already knew that too)

But I also have other issues :

WIFI tethering not working (the hot spot seems to fail immediately at activation)

Turning off Bluetooth makes the device reboot instantaneously

I haven't even tried to look at the logs so far, just would like to know if you guys encounter these issues with the builds from T_I, or is it only my build that is corrupted or missing something somehow ?
[Galaxy Tab S2 Original Android Development] Snilmerg:
I confirm those issues with your latest build on a T715 :

Camera not working

Automatic brightness not working

WIFI tethering not working (the hotspot seems to fail immediately at activation)

Turning off Bluetooth makes the device reboot instantaneously

Home button not working (had already noticed that with my own build)

Fingerprint not detected
[Galaxy Tab S2 Original Android Development] nostupidthing:
Fingerprint too
[Galaxy Tab S2 Original Android Development] T_I:
Camera worked on cm13.0 build of 29-11-2016 and earlier, lte build only. (worked with that build on both devices)

BTW strange that home button doesn't work in T715, have no issues with the home button on T710. Bluetooth has been an issue for a while, turning it on will fail first try, leave settings and try again and on my devices (wifi) it'll work the 2nd and following tries after a boot. (I see no reboot)
[Galaxy Tab S2 Original Android Development] Snilmerg:
Actually, the Home button must be "working" in the sense that it is detected : when I press the home button as the tablet is asleep (I mean when it's on but screen turned off), it awakes the screen. But in normal usage, in app, Home button pressing just does nothing. I tried configuring the settings of home button "long press" and "double press", these actions seem to be detected once, then never again.

So to be more precise, I would say the button is detected as a hardware, but only its actions seem to be ignored / incorrectly handled.

Also, the button works fine when I am in TWRP, so I guess we can probably rule out the hypothesis of this being an hardware issue only on my tablet.

[MENTION=4929354]nostupidthing[/MENTION] : by any chance, do you have the home button pressing issue too (not talking about the fingerprint issue) and what model do you have ? T710 ?
[Galaxy Tab S2 Original Android Development] nostupidthing:
Sorry I have a T710 and no home button issue here
[Galaxy Tab S2 Original Android Development] Hapoofesgeli:
Just installed the ROM after breaking my stock one in attempts of de-bloating all those "stuff"...

Bluetooth works, just a bit glitchy

WiFi tethering works

Vibration works

Home button is also working (a bit hard to wake the device with tough, needs firm pressure, kinda weird)

Fingerprints, adaptive brightness and camera would be nice to have but not really a deal breaker on tablets, I will stick with this as my daily driver unless something comes up. Thanks for the work.

---

Edit: WiFi tethering breaks whenever there is radio available, but works fine when there is no sim.
[Galaxy Tab S2 Original Android Development] Snilmerg:
[MENTION=5538814]Hapoofesgeli[/MENTION] I am not sure I understand. I fail to see how WiFi tethering can "work fine when there is no sim" (I assume you mean "no sim card" ?) since, to my understanding, WiFi tethering is the feature of sharing your mobile connection through a WiFi hotspot.

Also, what is your model ? T710 ?

thanks for your feedback.
[Galaxy Tab S2 Original Android Development] Hapoofesgeli:
It's actually not the sim card, but having data available. Without it, the tethering option creates a working access point and you can get a network established which can be used to share files etc but no internet connection since you have to turn data off (you can make an access point even with data on despite the error message shown but you can't actually connect to it due to IP resolving issues)... And besides that USB tethering is also broken in the same manner.

And I'm using T715.
[Galaxy Tab S2 Original Android Development] Snilmerg:
There are two files from vendor blob that seem related to the camera (based on their name) :

vendor/samsung/gts2-common/proprietary/lib/libexynoscamera.so
vendor/samsung/gts2-common/proprietary/lib/hw/camera.universal5433.so

I noticed libexynoscamera.so isn't present on my device, in /system/lib nor in /system/vendor/lib

In my build environment the file seem to have been prepared and packaged in the image (the file exists in "out/target/product/gts28ltexx/system/lib/", and appears in the file "out/build-lineage_gts28ltexx.ninja", which I guess is involved in the build process ?).

Could the absence of this file be a part of the cause of the malfunction ?
[Galaxy Tab S2 Original Android Development] T_I:
Could be, but then I'm curious why the camera works without it on T810. Something to dive into. New laptop is taking time, rebuilding build environment on slower hardware.
[Galaxy Tab S2 Original Android Development] Philippovitsch:
I found something interesting in the logs. When opening the Camera-App I got a lot of errors with ExynosCameraNode:

[ 09-08 10:43:48.658 2641: 3532 E/ExynosCameraNode ]
[CAM_ID(0)][flite]-ERR(m_setControl):exynos_v4l2_s_ctrl(fd:7) fail (-1) [id 10096654, value 655361]

[ 09-08 10:43:48.658 2641: 3532 E/ExynosCameraNode ]
[CAM_ID(0)][flite]-ERR(setControl):m_setControl fail

.....

I didn't got any messages that it is missing libexynoscamera.so or camera.universal5433.so. (Just got a message, that it is missing libwvm.so, which was removed some time ago)

Could it also be a Media-Codec Problem? (got also some Errors with the Codecs)

Attached a logcat for that reasons. (Camera-App starting at line11733, ExynosCameraNode Errors starting at line 16599)
[Galaxy Tab S2 Original Android Development] T_I:
My development system has been replaced, as it died on me. First test build has been uploaded (OP updated). Nothing more then a recompile with security patches, but the environment works again.
[Galaxy Tab S2 Original Android Development] T_I:
I'm afraid that development has almost grinded to a halt at the moment. My currect contracting assignment doesn't leave enough spare time to dive into the code.

However, I managed to get a build with the latest security patches, OP updated.
