LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (Pie), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Reporting Bugs

DO NOT Report bugs if you're running a custom kernel or you installed Xposed

Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)

If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)

If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

Anyone installed this yet?
[Galaxy Tab S2 Original Android Development] Oh_ehi:
*deleted*
[Galaxy Tab S2 Original Android Development] Dnorris55:
Yes, I got it installed after a bit of fumbling around.

The key seems to be the gapps. I first tried the open_gapps-arm64-9.0-stock-20180815-UNOFFICIAL.zip found on XDA, but it caused several problems with Pixel setup, etc.

Finally found BiTGApps-arm64-9.x.x-0.1-unsigned.zip, which is very minimal. It worked great.

HW button lights not working, but otherwise all seems fine.

:good::good::good:
[Galaxy Tab S2 Original Android Development] itsamess:
Thx, Luk1337 for your work.

I will wait this time and hope for official (so hopefully no clean Install)
[Galaxy Tab S2 Original Android Development] :
just installed it, looks good, thx
[Galaxy Tab S2 Original Android Development] nnortel37:
Just installed. All is fine. Thanks.
[Galaxy Tab S2 Original Android Development] spacepille:
It is not working for me. No matter which gapps I install, every time google play and bluetooth apps are crashing and randomly also the whole pixel setup. Unfortunately for me unusable.
[Galaxy Tab S2 Original Android Development] Dnorris55:
Try a clean flash of ROM and Gapps?

I tried dirty flash of Gapps over Gapps and it didn't work.
[Galaxy Tab S2 Original Android Development] spacepille:
Yes, I formatted data and system partition before each installation and did factory reset. I tried with all possible pie gapps I could found. Also without installing gapps. Every time the same result. Very strange.
[Galaxy Tab S2 Original Android Development] universeman:
Same issue. Are you flashing lineage-16.0-20180815-UNOFFICIAL-gts28vewifi.zip or lineage-16.0-20180817-UNOFFICIAL-gts28vewifi.zip?

---------- Post added at 06:02 PM ---------- Previous post was at 05:06 PM ----------

I think I figured it out. The errors only occur when my MicroSD card is inserted. It was prompting me on how to use the card, but I had not formatted the card.
[Galaxy Tab S2 Original Android Development] grakor:
Is Google assistant working for anyone? Half the time says unable connect, the other half the mic doesn't work.

Besides that, very promising and will be my daily rom :)
[Galaxy Tab S2 Original Android Development] tjupille:
Kudos on getting this out so soon, and with minimal bugs. It's really smooth -- ready to be my daily driver.

Minor issues that have cropped up over 2 days of regular use:

- Google Assistant works but it *is* a bit flaky. I have to re-enable it as the default assist app after every reboot.

- None of my apps / widgets that access the SSID information work (they run, but display no information). I'm not sure if this is due to this ROM or to Android Pie in general.

[update: Problem solved. Settings > Security & privacy > Location > Advanced > Scanning > Enable Wi-Fi scanning did the trick! ]

- Battery life was about half of what I was getting with stock Nougat using the "medium" battery saver setting. I fixed that problem with the "Power Booster" app from the store (although any of the CPU tweaking apps should work as well).

I'm really hopeful that we'll get an Xposed version for Android Pie so I can get the rest of my favorite tweaks in.

Any way of rooting this?
[Galaxy Tab S2 Original Android Development] Dnorris55:
I was very glad to see that! [emoji106][emoji106]
[Galaxy Tab S2 Original Android Development] tjupille:
I think it's pre-rooted. In any case, I installed Magisk.

Update: There is "root access" setting under "developer options". Mine shows "disabled", presumably because Magisk is controlling root access.

Tried to install last night and ended up with a black screen. It booted to initial screen and then sat there saying "Wait a Sec...". I rebooted but was unresponsive with a black screen. I let the battery run down and rebooted to recovery and restored 15.1. I installed the ROM 3/31 build, Open Gapps, and Magisk. Did Magisk cause the issue? I want to try again. Maybe a different Gapps and newer build?

Thanks for any tips. I didn't see this issue listed in previous posts.

Cheers,

Won't Sleep?

ROM works great, but not getting into sleep/deep sleep... and consuming battery, 100% to 65% in 12 hrs. Have tried most of the usual things, including checking for wakelocks etc. Any way to get it to sleep? thanks! jf
[Galaxy Tab S2 Original Android Development] wasabij:
I'm in the same boat. My battery life says it's gonna go from 100 to 0 in just over an hour of SOT
[Galaxy Tab S2 Original Android Development] lmacmil:
I'm on the 3/18 build. It loses 1-3% in 12 hours with wifi off and all apps closed. When not in use it's in deep sleep for about 95% of the time. AccuBattery says 13%/hour drain with the screen on. I don't play games or watch movies, mostly browsing or reading.
[Galaxy Tab S2 Original Android Development] rholm:
3/18 rolled of the board. Did you install Magisk? And, what gapps did you use? I love Pie on my Essential Phone and would love to use it on my 713. My previous attempt to install 3/30 had big issues.

Thanks!

[Galaxy Tab S2 Original Android Development] Dr. Drax:
Inverting lock screen

Crazy question: is there any way on this build to force the lock screen into inverted portrait? I always use my tablet upside down. It'll rotate the lock screen to inverted if I happen to have rotation unlocked, but most of the time I need to lock rotation to keep misbehaving apps from forcing my display to regular portrait. (For some reason, a ton of developers make their manifest set android:screenOrientation as "portrait", when it should be "sensorPortrait".) And forcing the rotation to inverted portrait in turn disables lock screen rotation, so the lock screen counterintuitively comes up portrait.

I have Magisk installed if that changes the answer. I appreciate any suggestions!
[Galaxy Tab S2 Original Android Development] lmacmil:
No Magisk or root. I used the latest MindTheGapps.
[Galaxy Tab S2 Original Android Development] friedsonjm:
Not deep sleeping..

Mine is rooted, update nightly, also lastest MindTheGapps.
[Galaxy Tab S2 Original Android Development] rholm:
Magisk for Root? I think I'll try again tonight. Thanks!

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] rholm:
Tried again with MindTheGapps. Still doesn't get past "Just a Sec". Letting the battery run down again. Do I need to install ROM and Gapps on separate boots? Is Magisk causing this? Is the 16.1 build broken?

Thanks!

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] friedsonjm:
I don't use Magisk - so I'm guessing that may be the issue. Are you using the correct MindTheGapps?
[Galaxy Tab S2 Original Android Development] rholm:
After the battery runs out I'll check. I think I used arm64. I'll leave out Magisk next time.

Thanks!

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] rholm:
I tried without Magisk. Nothing works. Has anyone done a fresh install with a build after 3/30? I've been installing custom ROMs and have never seen this. It just never goes past "Just a Sec". When I restore to my 15.1 backup, everything runs fine on my table.

Not sure what to try next.

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] friedsonjm:
Battery Usage Much Better Now

Running last night's build (4/8/19) not sure exactly when things changed, but barely using a juice now when not in use... yeah!
[Galaxy Tab S2 Original Android Development] rholm:
Was that a clean or dirty flash?

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] rholm:
Anyone try installing the ROM. Rebooting system. Then, rebooting into recovery and installing Gapps?

Thanks!

Cheers,

---------- Post added at 07:33 PM ---------- Previous post was at 06:51 PM ----------

Ok, just installing the ROM gets me into the locked up state, with a black screen. Anyone want to share a build that installed from scratch? I would greatly appreciate it. No builds since at least 3/30 install to a workable system.

Thanks!

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] nurunet:
I'm interested in this as well... My wife just got a 713, and I'd prefer her to have a more up to date Android on her device. However, if there are currently issues with the installation, I will wait.
[Galaxy Tab S2 Original Android Development] lmacmil:
Check your messages.
[Galaxy Tab S2 Original Android Development] optionalmgrr.la:
Ruiing very fine here. Upgraded from Los 15
[Galaxy Tab S2 Original Android Development] rholm:
Just tried 3/13. Still doesn't work. I need to check my version of TWRP. Anyone know what version they are using? The latest seems to be 3.2.3. I'm not sure what I have. Need to wait until the battery runs out.

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] lmacmil:
That's what I used.
[Galaxy Tab S2 Original Android Development] rholm:
I'm going to reflash recovery and try again this weekend. Can't see what is the issue, it runs 15.1 fine. I wonder if something is corrupted or maybe HW about to fail?

Thanks for your help!

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] lmacmil:
At this point, since no one else seems to be having this problem, it's almost got to be a hardware issue or a technique issue. Although if it was hardware, hard to understand why 15.1 would run fine. Maybe a list of the each step of the process would give someone a clue as to why the installation is failing.

Good luck.
[Galaxy Tab S2 Original Android Development] rholm:
I agree. Unfortunately, I seem to be the only one.

I have tried variations of flashing the ROM, gapps, and Magisk. I tried not flashing Magisk and not flashing Gapps and Magisk - just the ROM. All end up with an endless "Just a Sec". In this state, I can hit back to set language and begin button. There is no way to go forward past the spinning circle with "Just a Sec". Eventually, the screen blanks and it becomes somewhat unresponsive. If I press the power button, I get a choice between shutdown or reset. If I select one, the menu goes away, but it doesn't shutdown or reset. I have to let the battery run down, then boot into recovery to restore my backup or try again. Even holding down the power button for 30 seconds to a minute won't force a reboot.

In all cases, I factory reset with a format of system. Next, I flash the ROM. I have tried with and without gapps and Magisk. For gapps, I have used OpenGapps and MindTheGapps. Pretty standard stuff.

Am I missing anything?

Thanks!

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] friedsonjm:
Dirty flash, standard nightly TWRP update.
[Galaxy Tab S2 Original Android Development] lmacmil:
Not that I can see. If the process works for 15.1, which it obviously does, the same process should work for 16. I guess there must be some type of hardware issue that's preventing you from installing 16.0 but I have no clue as to what it might be. I didn't see any real performance benefits to 16 over 15.1 but since my phone is on Pie, I like having both devices on the same Android version.

Since running 16 for about a month, I have had two instances where I lost my wifi connection. When this happened on 15.1, I just restarted and all was fine. With 16, when I went to settings, I got a blank screen. When I tried to restart, I got the spinning circle and it just hung there. I had to hold home, power, and volume down keys to get it to shut down. Once restarted, it was fine again. Even with the stock ROM, I would lose the wifi connection (and the ability to see the router) but I could always restart and that fixed the problem (until the next time.)

Despite these minor inconveniences, I think 16.0 is a great ROM and it makes me love this tablet even more.

Hello, could someone please point me to the most current/preferred guide for rooting the SM-713 for Lineage 16? I'm quite comfortable with following the steps - having used Lineage and CM for many years now - but this is my first attempt with a Samsung device. I've found several guides for the SM-713 here and elsewhere, but they all seem to be quite old. Since I'm starting fresh and from the most recent Samsung update, I'd like to avoid inadvertently messing up. Thank you in advance, especially if I've missed something obvious on XDA.

EDIT: This is the most current one I've found so far: https://xdaforums.com/showpost.php?p=78968923&postcount=230

No deep sleep

Unfortunately same here... I love the ROM, but I have this important issue.

I fresh installed 04/12 release and yesterday 04/14 release but this morning I still have the tablet consuming battery like crazy when in standby (nasically not entering the deep sleep mode).

I don't have root, don't have magisk and installed latest openGapps micro arm64 version.

Any ideas on what I could do?

EDIT: I've found a solution by myself... Thanks to this post https://xdaforums.com/showpost.php?p=78607752&postcount=406 you can just use Automate with the described flow. Did it a couple of hours ago, the tablet is now entering into deep sleep mode properly
[Galaxy Tab S2 Original Android Development] lmacmil:
Turned my tablet off about 10 last night. Didn't look at after I hit "turn off." This morning about 7:30 I opened the cover and see it says "turning off." It never completely shut down last night. Had to do the "3 finger salute" to get it to reboot, after which it was fine. On the plus side, the battery only drained from 58% to 24% even though it spent 9 1/2 hours trying to turn itself off. Yet another issue that seems to affect only one tablet. Very strange.
[Galaxy Tab S2 Original Android Development] guinnes.s:
Is it possible to increase the overall volume level? It is to lowwwwww[emoji44][emoji33] . Thanks
[Galaxy Tab S2 Original Android Development] optionalmgrr.la:
the 20% battery reboot bug is still there :D

other than the higher than usual battery drain this rom is perfect
[Galaxy Tab S2 Original Android Development] :
Guys, for the last week or so, I have been experiencing an unusual problem after OTA updates. When the tablet reboots after the update, it will not see the SD card. Restarting it does not solve the problem. I have to shut it down completely, however when I turn it on again, it will get stuck at the LOS boot animation and will not shut down, no matter how long I keep the power button pressed. The only way to recover is to perform a hard reset (power button, volume up & down, home button). After that, everything works properly, including the SD card.

Has anyone else seen this problem?
[Galaxy Tab S2 Original Android Development] rholm:
I get this when I try to install for the initial boot. I cannot get to the setup screen. Tried many things, but no work around.

Cheers,

Rich
[Galaxy Tab S2 Original Android Development] BhNeP:
Does anyone recognize the following problem?

I installed a recent LOS 16.0 image + gapps through TWRP 3.2.3. It installs fine,l and I then install magisk and apps. Everything is running fine. But after a while (it may be just a day or sometimes up to a week or two) when after I shutdown and (re)start the system, the bootup shows me the usual logos, then my desktop for about a second and then reboots into recovery.

From then on there is no way to do a system reboot or even shutdown from recovery. The tablet keeps booting into recovery until the battery runs out.

I've tried different LOS16 images, gapps but after a while it will happen again.

What does work is to install a backup of the previously running system from recovery. But then the waiting game starts all over again.

Any ideas?
[Galaxy Tab S2 Original Android Development] friedsonjm:
I'd have to look back through the postings, but I think you are at least the 2nd person who has had issues... and is trying to use Magisk....
[Galaxy Tab S2 Original Android Development] tek3195:
You may want to look towards Magisk. I have a galaxy grand prime on LOS14.1 doing the exact same thing running microG and magisk. I avoid current data loss from using backup by dirty flashing. OK I just installed this rom on my Galaxy tab s2 yesterday and I gotta ask, is there no clear all for recents or am I just missing it? I installed with microG and Magisk. Any tips on Xposed? If answer is in this thread I'll see it in a min. Wasn't planning on posting anything yet as I've not read thru thread, but seen the recovery loop thing first.
[Galaxy Tab S2 Original Android Development] lmacmil:
Anyone getting decent battery life out of a recent build? I'm still on the 3/18 build and am reluctant to update unless I know the newer build will be as good.
[Galaxy Tab S2 Original Android Development] BhNeP:
I would hate not to be able to use Magisk. For now I try to avoid rebooting and making daily backups,

You can find Clear recents by swiping right to the far left of the recents screen.
[Galaxy Tab S2 Original Android Development] friedsonjm:
I update daily, and its a bit strange.. some days left at almost 100% I'll come back after about 12 hrs and have 70% left, others, like today, 92%!

May have something to do with what I run, but darned if I can figure it out yet...
[Galaxy Tab S2 Original Android Development] lmacmil:
What build gave you 92%? Assuming your usage is fairly consistent, the only variable is the build.
[Galaxy Tab S2 Original Android Development] LibiSC:

Where can i get that build?
[Galaxy Tab S2 Original Android Development] tek3195:
Did yours stop looping? I'm using magisk and microG on this tablet as well and it done it a few times and straightened out after that. I think there was a Magisk update or I may have switched to beta channel. Can't see where you would ever have to stop using it for something like that though, you can always switch between release channels or roll back to last functioning version. Oh, yeah found the recents button after changing wallpaper that it blended perfectly into. Thanks

Oh, and I wasn't meaning make daily backups. I dirty flashed rom and userdata stays intact like nothing ever happened.
[Galaxy Tab S2 Original Android Development] friedsonjm:
I wish I could remember which one. I check and if available update daily.
[Galaxy Tab S2 Original Android Development] lmacmil:
Based on the date of your post, I updated to the 5/8 build today. We'll see how it goes.

Update: battery drain was 8% over 9.5 hours with wifi off. The 3/18 build I was using would lose about 2% under the same conditions.

Another update:. Only in deep sleep for 24% of screen off time with wifi on. That's much worse than the 3/18 build.
[Galaxy Tab S2 Original Android Development] lmacmil:
In the first overnight test of the 5/8 build, I turned wifi off but left Chrome and one other app open. Last night I closed all apps and turned off wifi and the battery only lost 1% in 11 hours. It was in deep sleep for 97% of screen off time for the previous 16 hours. This is consistent with the 3/18 build I was using previously. I proclaim this build excellent for battery drain! :)

The next night, drain was 0 in 10.5 hours! This one's a keeper!
[Galaxy Tab S2 Original Android Development] Dr. Drax:
Will there ultimately be beta and/or release versions for the T713? Or will there only be nightlies?
[Galaxy Tab S2 Original Android Development] lloydsw:
What version of TWRP are you guys using to flash this?
[Galaxy Tab S2 Original Android Development] Laz35:
Awesome! That's a great find. Unfortunately it seems builds that old are not available ?

Where did you find it?
[Galaxy Tab S2 Original Android Development] lmacmil:
It was the oldest one on my updates page when I downloaded it on the 12th or 13th. My plan was to start at the oldest available update and flash a new one every day until I found one with acceptable battery drain. This one was good enough I didn't have to continue.

Last night I forgot to turn wifi off and the battery lost 6% in 9 or 10 hours with no activity.
[Galaxy Tab S2 Original Android Development] optionalmgrr.la:
im getting 20% for ~1-hr SOT with this great ROM, is there anyway to prolong that?
