Joining forces with the Exynos Note 4 devs

I have joined the pre-existing Exynos5433 GitHub account in which the Exynos Note 4 (treltexx) is being maintained by ananjaser1211, who is an RD/RC, and McFy, an RD, and moved my gts2 repos into it.

We will benefit greatly from their expertise, as they have been working from bonuzzz's treltexx sources that are older than the gts2 ones that I am maintaining.
[Galaxy Tab S2 Android Development] hurray:
Very nice to see that there is still life in developing for the Tab S2.

I use the Tab S2 still every day for reading. :)

I will try LOS 15.1 in a few days when I have more time.

Merry Christmas!

Nice to see someone else picking this up again. I just couldn't after the concussion. Did a build myself yesterday and noticed that in Live display only the profile is working slightly, or not at all. (can't see big changes) Changing the colour temp doesn't result in any change. In bonuzzz's build this worked, in the cm 14.1 builds I put together this worked only after changing 'anything'. Live display settings weren't set on unlock and I never could find where and how to fix this.

I've built the sources for testing using the same scripts I used for cm-14.1, so all devices are built. As usual I uploaded to androidfilehost, with the T810 images in https://androidfilehost.com/?w=files&flid=287625 . The T710 images are tested and work, bar live display, didn't have time yet to test the T810 images. (so be warned)

No deep sleep and SD card can not show any content. SD card works fine in TWRP.

Could you update what is not working in your OP?
[Galaxy Tab S2 Android Development] ripee:
Will do, later today.

As for deep sleep, that needs more work, as bonuzzz seems to have found a trade-off between it and the fingerprint sensor. Naturally both need to function independently of each other.

Edit: I just merged this SD card fix, courtesy of schwabe93. It will be in the next build.
[Galaxy Tab S2 Android Development] srvoleti:
Please look into the deep sleep issue, this is consuming a lot of battery overnight. Many thanks for supporting this device . I am using your builds only and every thing is fine except the deep sleep issue. May be you can make a build disabling the fingerprint for those of us who can live without it but with deep sleep and better battery backup. Hope you will consider my request.
[Galaxy Tab S2 Android Development] hurray:
Regarding the deep sleep problem: I am currently on LOS 14.1 and have had similar issues in the past. I solved it with Greenify where I use the features "aggressive doze" and "use doze on the go" (which prevents waking up the device during a walk) and disabled "shallow hibernation".

Since then my Tab S2 is sleeping very will besides I have to annotate that I have completely disabled WiFi and Bluetooth if the Tab S2 is sleeping (I don't need it on the tablet if it's sleeping).

Maybe it is worth a try on LOS 15.1 also as a workaround. :)
[Galaxy Tab S2 Android Development] Meakii:
Will give this a go and report back. :good:

Edit: Sadly still the same result. 99.7% awake with screen off in BetterBatteryStats. Will have to wait for a fix I guess

0905 update working great on T710. Performance and battery is excellent.

- Fingerprint unlock stops working after first use. Works once after device restart and manual unlock. Once after deleting and adding fingerprints again. Occasionally once more some random time.

- Open camera takes pictures. No video recording. Default camera app is still missing.

Edit: I think I spoke too early. I'm getting frequent freezes and restarts. HD video playback is also jittery. I did dirty flash over the 0901 build.
[Galaxy Tab S2 Android Development] bmwdroid:
Came from LOS14.1 which worked without any problem.

Made a clean installiert (full wipe&Format data) with pico.

Camera app existing and working.

Fingerprint was exepted but didn't unlock.

Regularly deep freezes to be restarted with extremly long power button pressing.

Gonna try the 0901.

Thx anyhow for your work.

With the 20190827 LOS16 build, I once got the SIM recognized on my T715, but mobile data did not work. Then I ran into the "fast battery drain" issue, the tablet got shut down. With the next boot, RIL was gone again and did not come back for the next 20 boot cycles.

Today I updated to 20190905, at the first boot I got no SIM PIN entry, but after one re-boot it appeared. I tested a phone call and it worked up to the point when I tried to hangup which was not possible. The dialer app hnagup button did indicate a press, but hangup did not work (see the dialer screenshot). Unfortunately I was connected to a voicebox so I had to re-boot to get out.

When I got the SIM PIN entry back (one more re-boot in-between), I checked if the phone has an IP address for mobile data but that was not the case (see the terminal program screenshot).

I pulled /proc/last_kmsg and a logcat (see attachments). Both contain some interesting SELinux messages related to RIL like:

avc: denied { ioctl } for pid=4227 comm="rild" path="/dev/umts_ipc0" ...

[MENTION=6005084]ripee[/MENTION] [MENTION=4637718]ananjaser1211[/MENTION] I hope this helps a bit for debugging. I keep fingers crossed that you get RIL fully working some day. This ROM is very promising, but I really miss mobile data on the T715.

T810 0905:

0901 Clean flash, data wiped:

Was working without problems for me, only a bit stuttery with multitasking/swiping apps and screengrabs not having right orientation after rotating the tablet (see screenshot).

0905 Clean flash, data wiped:

- Fingerprint sensor seems to work only for first time after power on. Feels more snappy, swiping apps is far more fluid. Is getting laggy after a while. After some more time completely hangs, display freezes. After a minute of hanging or so tablet restarts into LOS, sometimes into TWRP. When it boots into TWRP the LOS booting animation is shown for (I guess) 3 tot 4 minutes or so.

- Problems with games: Powerpuff Girls Monkey Business (new on my device, not tested earlier) + Knightmare Tower (running OK on 0901): Screen freezes, game continues to run (sound hearable, screentaps registered). Also after hanging for a while it reboots into LOS and sometimes into TWRP.

- Playing Youtube videos results first in framedrops, then completely hangs.

[MENTION=6005084]ripee[/MENTION] & others: I have created some syslogs during using the tablet for about a day. I'm new to this, so if any essential information is missing or could be improved please let me know :)
[Galaxy Tab S2 Android Development] metterschling:
Note that a workaround to get RIL recognised seems to be to re-boot into recovery, then wipe Cache and Dalvik Cache, then re-boot into system.

Made a strange experience yesterday. While charging my T810, it was off, I pressed the Power-button but nothing happened, not even showing that it's charging.

Really had problems to turn it on, had to went via TWRP, which even took some time to start.

Good day. Ripee, thnx for your work! Testing your last 0905 build of LOS16 on T815. No RIL at all - saying "no sim" and a lot of stability issiues:

- mx player with hw+ decoder reboot tablet very often

- some scrolling issues on greader, firefox, EBookDroid - screen became dark, fixing by swithing to another app and back

There is official T810 LOS16 build https://download.lineageos.org/gts210vewifi - may be it could help you to make LOS16 for other tablets more stable.

same here, T810. Had problems to get into TWRP to flash the previous version.
[Galaxy Tab S2 Android Development] Ekstr:
Didn't get through LOS booting animation with 0910 on my T810. Was able to put 0901 back with TWRP succesfully.

Had to disconnect the battery (I had unit open already anyway) to disconnect power. Booted succesfully into TWRP again.

0910 file has been deleted from server (probably Ripee is already aware of problem I think), if you already downloaded it maybe is better to wait for an updated version :)

Back to 0901 for me, which is stable in my use. As with GApps Pico 0910 I experience the tablet to be a bit faster and more responsive though.
[Galaxy Tab S2 Android Development] bmwdroid:
Tried a dirty flash of 0910 on top of 0901.

Bootloop.

Very hard to get into TWRP again.

Only possibility was to get into download mode, restart and switch to pressing Vol+ and home buttons.

Then I flashed 0901 dirty again.

Then it worked again.

Did more testing on T815 with 0905 - video playback more stable (no reboots) with MXPlayer on SW decoder instead of HW+.

Did you flash any gapps package. If so, I strongly recommend you to flash Pico or micro package, otherwise you may get a bootloop. It happened to me.

Thank you. :D

Correction: I'm charging my tablet (T810), turned it off. Now while charging it's not showing that is's charging when pressing the power button for a short time like before.

And: Can't turn it on. Have to force it again via hard(est) reset, download-menue.

Am afraid sooner or later turning on is failing completely.
[Galaxy Tab S2 Android Development] Ekstr:
0910 T810 Clean flash + data wiped, GApps Pico 0911:

Haven't had a forced reset or crashed yet after using the tablet for 3 hours so far.

Booting into TWRP worked without issues, although I use 'Quick Reboot [ROOT]' app to boot into recovery due to partially broken (hardware issue) power button & volume buttons.

I experienced a couple of issues though:

- When playing videos in Youtube app video area remains black. Sound of video is still hearable, rest of app content is visible. Starting a video takes about 10 seconds before being played. App doesn't crash and can be used without any additional problems.

- Games are not loading properly. It loads the splash and introduction screen, when loading gameplay itself screen remains black. Tablet seems to hang for a while but doesn't lock up or force reboots. Switching apps and closing the app by swiping it up returns tablet to working operation again.

- Screengrabs remain black in app switcher for some apps, also incorrect landscape/portrait orientation in screengrabs shown.

- I noticed lags while using apps. I haven't experienced before or in earlier builds. While app loading times are bit shorter (sometimes even snappy) app performance varies in my experience.

Please let me know if more specific testing or more logs are needed :)

Youtube vidoes are loading very slow. no live stream videos working. twitch not working. same with mixer. live videos dont play.
[Galaxy Tab S2 Android Development] Ekstr:
Addition to my latest reply:

- Lag in apps and overall use are gone in most cases after some more hours of using + leaving tablet unused for while.

- Velocity of swiping apps and selecting apps from left to right (and vice versa) is not in overdrive anymore. It's now easier to select the wanted app in app switcher. Also velocity is more accurate (moving finger to the right/left faster) results in correct velocity.

- Apps are loading faster and feel more snappy while using them.

I noticed same behaviour on a previous build also. Could it be that Pie has a sort of optimization mechanism built in, which comes to fruition after a day of use, or is it something else what causes this?

Anyway, 0910 build has been stable (=no unexpected OS crashes) today. Will keep using it and report if I experience more issues.

Edit: Just had a crash while using NOS app.

App and screen hangs. Then screen turns black and tablet quick reboots to lockscreen. See attached syslogs :)

LineageOS 16.0 T710 -Streaming Video doesn't work

I installed lineage-16.0-20190910-UNOFFICIAL-gts28wifi yesterday on my SM-T710, everything seems to be working (I haven't tested the camera or Bluetooth, I don't use them very much) and sometimes fingerprint. However streaming doesn't work. I've tried Plex (in both the app and multiple web browser), multiple TV streaming apps like Food Network, HGTV, NatGeo, Twitter, Reddit (again in their apps as well as different web browsers) and they all have video play back issues (and obviously audio doesn't). YouTube does work along with any local media (using VLC for local media). Has anyone experienced this issue?

Another addition to my previous replies :)

No reflash done since my last post update.

GApps Pico has been updated to 0912 meanwhile.

Tablet hangs after about 5 hours not using it and then using it back again.

Screen freezes, screen touches and touching back button are registered, but those actions are only applied when screen is accessible again.

I Hope attached logs are useful for troubleshooting :)

lineage-16.0-20190910-UNOFFICIAL-gts28wifi thinks device is lte

I attempted to install lineage-16.0-20190910-UNOFFICIAL-gts28wifi on my 2015 vintage SM-T710. the flash errored out with a message suggesting i was trying to install an wifi version of the code on an lte device. i then tried installing lineage-16.0-20190910-UNOFFICIAL-gts28ltexx, which worked.

several questions:

1) the lte code includes the phone and messaging apps. is there any way to delete them?

2) does it even matter?

3) what caused this?

Well yes you can do that, but it doesn't remove them from the tablet completely. I'd like to just not have them at all without rooting and uninstalling them.

I believe it solved my issues with lag and not able to (re)boot properly. It also may be that changes in the new version of ROM improved the situation.

Running 0914 on my T810 now, so far so good and faster than ever before (even compared to Samsung stock ROM). Will do some more testing and come back with results at a later time.
