Anyone having battery troubles with the latest nightly? Im just asking because im trying to figure it out. I had it go from 100 to 80 in a second the first thing I thought is its my tablet i had to replace the battery once before it died. But I read in the comment section people having battery troubles and it kinda fit as charging was really taking awhile. So I went back to lineage 15.1 and it seems to be working fine for now. I would think its more hardware problem but really I dont want to rule out software yet because it does play apart if you dont have the right software it wont magically charge.

However the rom seemed to be working great ive stayed away from pie because of xposed but now theres edxposed which gives me a couple things mainly If I use xinternelsd with exSD magisk mod I figured out how to get sdcard to have write access on my apps. you gotta set path /mnt/media_rw/sdcardnumber/ on the xinternelsd xposed mode then flash magisk mod boom sd card works like a champ. Im getting the word out.

Example /mnt/media_rw/B032-EFA0/ path to internal Sdcard.

I'm also having battery problems and thought the same as you and replaced my battery, but the problem persists.

Notice this on my errors log after switching to gapps pico, any possible solution or fix?

4/16/19 9:13 AM: Destroying /data/user/0/media due to: com.android.server.pm.PackageManagerException: Package media is unknown

As for battery life, it has been solid for me, around 7 hours SOT.

Loving the updates from 4/14 and above.

I have not seen any 4.9 kernels ported to this device yet.
[Galaxy Tab S2 Original Android Development] Techguy777:
Sent from a Galaxy tab S3 lucky dog. Yes I wanted to make sure before just assuming anything but I have been back on lineage 15.1 for days no problem what so ever. It gets old to hear the developers say not possible thats hardware your chip controls your battery and it has nothing to do with the rom. Then they say update they fixed the problem. Or my favorite is kernels because they say nope doesnt have the ability to change things like charging but then they say now has quick charge usb which it always had when you bought it. It can be both you need software for your hardware to work but you also need good hardware so I look at both. Hopefully you didnt spend to much on battery but at least you have a backup now.
[Galaxy Tab S2 Original Android Development] Atreya1:
I have both s2 and S3 both with mirror apps. Only difference S3 is on Android 8 official from Samsung run both the exact same way. The S3 holds its charge whereas the s2 running on lineage the new battery runs down more noticeable than the S3
[Galaxy Tab S2 Original Android Development] bschatzow:
I am having long startup time since installing this rom. I went from 15.1 did a complete wipe . Sometimes it sits at system is starting rather than the lineage icon. Never saw this screen before. It doesn't happen every time but enough to be a problem. Anyone see this?
[Galaxy Tab S2 Original Android Development] thisisapoorusernamechoice:
Is anyone using any magisk modules to improve battery life or performance? I'm using magisk 19.0 with iOS emoji, Sony-Music4Magisk, Systemless Hosts, Universal GMS Doze, and Youtube Vanced. Just curious if anyone has any recommendations. Thank you so much to LuK1337 and any other maintainers of this device, I actually synced the device tree and build myself crDroid Pie with it. Loving this tablet without the Samsung BS on it.
[Galaxy Tab S2 Original Android Development] pastorbob62:
Did you download the correct version of gapps? e.g. 64 bit?
[Galaxy Tab S2 Original Android Development] Techguy777:
There's no doubt in my mind the lineage 15.1 S2 is running fine. It's not great battery life but it's never really been great on stock either. The lineage 16 rom from a few updates ago was terrible I thought my tablet was dying it wouldn't charge the battery died quick. I was really leaning on hardware myself being problem when the battery jumped from 100 to 80 in about 5 seconds off the charger. That could be a fake reading not that the battery actually died quickly sometimes I jump into twrp and my battery reads different than rom. I'm a little worried about 16 again I probably end up trying it sometime.
[Galaxy Tab S2 Original Android Development] Svoel:
Yeah I did, managed to fix it by clearing data on storage manager under settings.
[Galaxy Tab S2 Original Android Development] OhioYJ:
See my post here. <-- Disable Wifi / Location, etc when the screen is off you'll have a huge jump in battery life. No need for Magisk Module. Just grant it root permission.

Hi,

See my post - https://r.tapatalk.com/shareLink?ur...hare_pid=79293882&share_fid=3793&share_type=t

I had almost no battery consumption with screen off even without Naptime. Since couple updates it consumes about 0.5%/h with Naptime so something changed for worse in this regard, just don't know how to debug it.

[Galaxy Tab S2 Original Android Development] RagingHarry:
The battery drain isn't that bad, left home to go to a weekend off in Eindhoven, left tablet on after full charge before leaving home.

Kept everything on as nor mal use, no naptime stuff installed, didn't change anything.

8 hours later battery was still 100% while idling in the suitcase in the back of the car during the day.
[Galaxy Tab S2 Original Android Development] CarlosCalderon:
I'm pretty frustrated about the battery performance. I have a drain of more than 1% per hour in standby. It doesn't get any better with the new releases.

Don't know what to do. Please help me, what I can provide so that you can help me.

I'm nearly on my way to sell that thing and buy an iPad...

[Galaxy Tab S2 Original Android Development] kdrkdr:
I have 0,6 % / hour with NapTime. Rom version 20160321. Perhaps rollback some versions?
[Galaxy Tab S2 Original Android Development] darzur:
It's still huge consumption. Couple of issues ago I've had ~1%/12h but now it's close to yours. I'm not sure what is the problem, but it might be "Find my device" that I have enabled some time ago. Have to check it.

[MENTION=5075128]LuK1337[/MENTION]

On this tablet I don't like the "reverse" layout of the capacitive buttons (Samsung!). So I've enabled the built-in navigation bar via editing build.prop. It's working good without any problems (at least for me).

What about adding an option in Android system preferences to activate this directly? Would be very nice! :)
[Galaxy Tab S2 Original Android Development] ammarr:
Same battery consumption issue here. Idle consumes at least 1%/hr, even when using NapTime to force deep sleep. BetterBatteryStats shows tablet in sleep most of the time and nothing keeping it awake. Running the latest nightly.

Anyone who doesn't have the battery issue?
[Galaxy Tab S2 Original Android Development] darzur:
It consumes that much even in safe mode so it's definitely some problem with ROM itself...

I was having battery problems! So I did a fresh install and didn't put any root on it. Now works a dream and little or no battery drain when sleeping
[Galaxy Tab S2 Original Android Development] optionalmgrr.la:
Wait till a few weeks and see.... :cool:
[Galaxy Tab S2 Original Android Development] ammarr:
I tried with no root after a factory reset as well and still getting the same issue unfortunately. Fresh install, no gapps, just firefox and netflix installed for testing. Battery drains at a constant 1-2% per hour.

This is a new tablet, around 3 weeks old, so don't think its a battery issue.
[Galaxy Tab S2 Original Android Development] RagingHarry:
Why don't you all with battery draining problems install Better Battery Stats and start monitoring idle draining and provide logs!
[Galaxy Tab S2 Original Android Development] ammarr:
BetterBatteryStats shows the device in deep sleep the entire time pretty much. Maybe ~2 mins awake over a 6 hour period. Not sure if a 6 hour log will help, but I'll attempt that as well.
[Galaxy Tab S2 Original Android Development] RagingHarry:
Check the BBS thread how to log idle!
[Galaxy Tab S2 Original Android Development] xpilot:
Same here. Tried to cast to fire TV stick using SM-T813 LOS16. When starting casting on the tablet, the Fire TV stick shows at least some reaction (establishing connection) but no picture. After a few seconds the tablet reboots.
[Galaxy Tab S2 Original Android Development] tsenidre:
Hello. I tried to connect my xbox360 controller on my SM-T813 with LOS 16 and OTG cable but it didn't work. The controller stay on blink state and no app recognize it. The same controller with the same OTG cable works on my Nexus 5 with LOS 14.1.

Does anyone connect the same controller successfully ? I've seen on the lineageOS subreddit someone says that the drivers needs to be included in the LOS build by the maintainer. But maybe I'm missing something.

Anyway thanks for the great work.
[Galaxy Tab S2 Original Android Development] Tha:
sorry to bump this thread, but is there a T810 version in the works? would be awsome to join the Android Pie club on my Tab S2!

keep up the good work guys, LineageOS 15 works perfect so far!
[Galaxy Tab S2 Original Android Development] socket84:
Hi everybody, what about if I try to install this version on my T815? It's boot without LTE module or it doesn't boot? Thanks
[Galaxy Tab S2 Original Android Development] jackspeed:
If you use the search button, you'll find some answers to your question;) It seems, it is not compatible at all due to a different SoC.
[Galaxy Tab S2 Original Android Development] socket84:
My bad and thanks for the answer. So right now I don't have nothing to flash on? Only lineage 14? ???
[Galaxy Tab S2 Original Android Development] jackspeed:
Sorry, don't know. I selected T813 due to the availability of LOS15.1, and I am thankful that official 16.0 is maintained.
[Galaxy Tab S2 Original Android Development] bschatzow:
Random Reboot -

I have a strange problem that started in Feb. I have a Samsung T813 with Lineage 16 and the latest Magisk. I get random reboots where the device goes back and then the system restarts.

It loads to my home screen but the touch is inactive. After several minutes it then loads another screen that says Tablet is starting. This takes about 10 minutes. It then boots into TWRP. If I go to custom wipe and clear both caches it will boot normally until the next either random reboot or a normal reboot.

I thought it might be failing hardware so I purchase another T813 (bran new) and loaded it the same as my old tablet. I just did a normal reboot after after making a change in the build prop and it exhibited the same issue.

Not sure if it is a Magisk issue, Lineage issue or maybe one of the Tasker programs that I granted root access. Any ideas?

I have now removed Magisk, and did a reboot and both devices still have this issue. So I don't think Magisk is a issue unless it left pointers in the wrong place.

I have never seen the screen tablet is starting before on any of my devices. Maybe this gives a clue on where to start?
[Galaxy Tab S2 Original Android Development] davidnw:
I have been using LinageOS 16 on a T813 for several months I may had one or two reboots or lockups that required rebooting but no anything like you are experiencing.

So I would suggest it is one of your apps.
[Galaxy Tab S2 Original Android Development] tenaka44:
Hi, I have a problem with my Galaxy Tab S2 T813 with Lineage os 16.

Very often the tablet freeze then reboot, I can't use it properly.

I have Lineage OS 16 (last update) and OpenGapps Pico, nothing else installed. Does someone have a clue with what's going on ?
[Galaxy Tab S2 Original Android Development] Essentrix:
Mine has been stable with OS 16 and Nano. Have you thought about using an earlier version for the initial install? I had some stability issues with later builds so went back some months to earlier build, installed then updated through included updater in ROM and seems to have solved the issue.
[Galaxy Tab S2 Original Android Development] bschatzow:
It's your device rooted? If so, with which program?
[Galaxy Tab S2 Original Android Development] mkdr:
What is not working on the T813 with LineageOs 16? Fingerprint? What about Netflix HD content? Will it work?
[Galaxy Tab S2 Original Android Development] jackspeed:
No problems at all here.

Fingerprint sensor does work.

Well, some people complain about the battery as you can read in this thread, but I got used to it.
[Galaxy Tab S2 Original Android Development] mkdr:
What do you mean, shouldnt battery be way better with it compared to Android 7 Samsung rom? What about Netflix Hd content, does it work?
[Galaxy Tab S2 Original Android Development] jackspeed:
Don't know. Flashed LOS 15.1 the day I bought it.
[Galaxy Tab S2 Original Android Development] OhioYJ:
I highly recommend you use NapTime to force the tablet into deep sleep when not using it. However note you will need to have it disable the WiFi, location, etc, to really notice a difference. Battery life is excellent with these items off. When I'm travel, and just watching moves from an SD card, I get excellent battery life. My last trip I had no problems getting 8-10 hours SOT.

With WiFi on it can be pretty random. I generally still get 6-7 hours though if I'm using it pretty regularly. My son uses his tablet in the what I would assume worst scenario for battery life (primarily gaming) and he generally can still get about 4 hours with his.

Netflix works, I don't know about HD. I do use MagiskHide Props Config v4.0.3 to change device fingerprint to certified one, so my device will show as certified. Otherwise Netflix won't even show up in the Play Store for you to install. You also need Busybox for that to work.

[Galaxy Tab S2 Original Android Development] supachris:
Hi.

I'm new to the T813 and want to use the encryption. But I cannot encrypt the tablet.

I'm using the latest LOS16, pico Gapps and SU, but starting the encryption ends in restarting the SystemUI only. I'm using a pattern. Is the encryption broken or do I have to do something other?

Thanks!
[Galaxy Tab S2 Original Android Development] OhioYJ:
It should be working. I've got several of these tablets, and am using both the PIN and Password options on them. I have not tried a clean install in a while though.

I know the latest version of TWRP appears to be broken with encryption.
[Galaxy Tab S2 Original Android Development] supachris:
OK, strange. I will try with PIN, but if TWRP cannot decryt, it is worthless.

Another thing: Can the soft buttons be enabled in the ROM? I have to do this manually after each update by using tweakProp for modifying the build.prop.
[Galaxy Tab S2 Original Android Development] Astania:
Is there a screen mode option implemented in Lineage OS?

I mean this
[Galaxy Tab S2 Original Android Development] OhioYJ:
The soft buttons have to be enabled by the build.prop modification as far as I'm aware, there is no way in the settings to enable them.

Just to make sure, which version of TWRP are you using? I know 3.3.0.0 had issues. I haven't tried 3.3.1.0 yet (just noticed it was released). I will try that when I get home today and see if encryption has been fixed. I'm still using 3.2.3.0 and it still works.
[Galaxy Tab S2 Original Android Development] FiReBReTHa:
im half way thru reading the whole thread, but weird question I hadn't seen mentioned in other threads...

After install, is the samsung galaxy store still available?

TIA!
[Galaxy Tab S2 Original Android Development] OhioYJ:
LOS does not include anything like this. You will not have any Samsung apps pre-installed. You can install Gapps if you wish which would load the Google Play store. I'm afraid I'm not familiar with the "Galaxy Store", but you are free to side load what ever you want. Assuming it's a market place I wouldn't be surprised if you have to use the Magisk Hide Module to change the device fingerprint to a certified one to make it work though. Not a big deal though.
[Galaxy Tab S2 Original Android Development] supachris:
I'm using the latest 3.3.1.0

The error according to CatLog is "Orig filesystem overlaps crypto footer region. Cannot encrypt in place." It seems to be that the data partition uses all the space and there is no space left for encryption...

Is this a TWRP issue while formatting the data partition initially?
[Galaxy Tab S2 Original Android Development] thomas2403:
TWRP 3.3x seems to be broken for our device when you are encrypted, look here:

https://github.com/TeamWin/Team-Win-Recovery-Project/issues/1466
[Galaxy Tab S2 Original Android Development] OhioYJ:
This has also been brought up in the TWRP thread as well a few times, I really hope it's being worked on. I don't know of any other new tablet with LOS support. The last working version of TWRP is actually 3.2.3.0 though. That works fine for me, any 3.3.+ version doesn't. 3.3.0.0 wouldn't decrypt data (but it would ask for a password). 3.3.1.0 doesn't ask for a password at all as stated.
[Galaxy Tab S2 Original Android Development] supachris:
Ok, thank you. I will try TWRP 3.2.3 and will report.
[Galaxy Tab S2 Original Android Development] supachris:
Yeah, it works! I downgraded to TWRP 3.2.3-0, formatted data, restored my backup and after this, I was able to encrypt. The tablet went into offline charging mode upon starting the encryption process, but after manual reboot out of the offline charging, the encryption started normally und now it is encrypted. TWRP is also able to decryp. Cool! Thanks for the hints. I hope, the ZWRP will be fixed...

Is anybody else having gmail troubles on Lineage? I don't know when it started, but for months now - on 15 and on 16 & with clean flash - I can't do things like open attachments or go to new messages from the notification bar.

We have two tablets on Los 16 with no serious issues with Gmail.

You could try another mail so like bluemail.

You could try another email app so like bluemail which would show if it was just your Gmail app and it's data or a wider system problem.

Root access

hello i have been running the Lineageos 16 most recent update as of 7/3/19 and i guess the rom is pre rooted? i have tryed to flash supersu from twrp and it flashes but then on the tablet the super su app says i dont have root access and other apps that require root are showing no root access as well as rootchecker, any help on how to root?
[Galaxy Tab S2 Original Android Development] supachris:
You have to enable the root in the developer settings after flash SU.

Hi guys does apps to sd or adoptable storage work with this rom, or using sd card as internal storage?
[Galaxy Tab S2 Original Android Development] fehrcomp:
Adoptable doesn't work at least there is no option for it under the storage section.
[Galaxy Tab S2 Original Android Development] marvi0:
Many thanks. That's a shame as have far too many apps and games as tablet is used by kids many thanks for your reply. Any work around for adoptable storage?
[Galaxy Tab S2 Original Android Development] Atreya1:
Just a thought have you tried partitioning the st card
[Galaxy Tab S2 Original Android Development] OhioYJ:
I've always enabled adoptable storage through the command line on my son's phone (there's been no need on his tablet)? Perhaps another route to try?
[Galaxy Tab S2 Original Android Development] OhioYJ:
So I looked at this again, it appears the old method that I use on my sons phone should work on these tablets as well. The SD card does show up as adobtable stoarge (My tablet running LOS 16):

If you want to try this, note it will erase your SD card and I haven't tested this on this device. So you are on your own, I'm not responsible for anything. It works still on KIWI, which is also on LOS 16.

Second I wish I knew where I found this information at this point, as I take no credit for this, I found this someone and saved in a text file, if someone knows the original source, let me know as someone else definitely deserves the credit:

Should just be a reboot after that.
[Galaxy Tab S2 Original Android Development] optionalmgrr.la:
Just found there's a power save profile option in battery, trying it now. To see if better battery life available.
[Galaxy Tab S2 Original Android Development] sebmue:
I'um using the 0714 build and have exceptional battery life. Even better than with stock, I would say.

Hi,

Is it possible to upgrade Vendor Security Level without reinstalling LOS?

I have LOS 16 running well but my Vendor Security Patch Level is 1 January 2018. I read there is a 2019 patch level available, but I can't find it.

Any help will be greatly appreciated.

Thank you
[Galaxy Tab S2 Original Android Development] davidnw:
See page 1 of this discussion. Builds -
[Galaxy Tab S2 Original Android Development] JamesKinds:
Hi,

Thanks for the pointer.

I may have been ambiguous in my original post.

I do have the latest build of LOS installed. The Vendor Patch file, which is typically installed as part of the default Samsung ROM, is what I was referring to.

I could get the latest vendor patch by reverting my S2 to the latest default Samsung ROM and then reinstall LOS, but I was hoping that there is a solution that doesn't need me to go down this path.

Said another way, can I update select partitions from the latest Samsung ROM and not need to reinstall LOS?
[Galaxy Tab S2 Original Android Development] JamesKinds:
Hi,

To avoid any more confusion, please see attached image. The attached file shows the Vendor Security Patch Level as 1 Jan 2018. The Android Security Patch Level is 5 Jul 2019 (Latest LOS).

My question: is it possible to update the Vendor Security Patch Level from 1 Jan 2018 to something more recent?

Thanks again,

JamesK
