Has anyone been able to get Roblox working on this rom? It opens but it's just a blank white screen with a black bar that flashes once in a while. You can sometimes click the login buttons behind it. Maybe a rendering/ppi issue? It works fine the stock samsung rom, but would much rather use lineageOS. This is a mostly fresh install (2 weeks old?). Updated to 20210111-nightly, no change.

LineageOS version: lineage-16.0-20210111-nightly-gts28vewifi

LineageOS Download url: https://mirrorbits.lineageos.org/fu...-16.0-20210111-nightly-gts28vewifi-signed.zip

Gapps version: 9-stock

Did you--

wipe: no

restore with titanium backup: no

reboot after having the issue: yes

Are you using--

a task killer: no

a non-stock kernel: no

other modifications: none

I don't run Roblox or have this tablet, but does Firefox Android browser give you a blank white screen when you load a webpage? If yes, I will tell you why I'm asking this question and a possible solution. If no, then nevermind.

Nevermind, I just looked at the T713 and it uses Snapdragon as per

Samsung Galaxy Tab S2 8.0 Wi-Fi SM-T713 - Specifications

Specifications of the Samsung Galaxy Tab S2 8.0 Wi-Fi SM-T713. Dimensions: 198.6 x 134.8 x 5.6 mm, Weight: 264 g, SoC: Qualcomm Snapdragon 652 (MSM8976), CPU: 4x 1.8 GHz ARM Cortex-A72, 4x 1.4 GHz ARM Cortex-A53, GPU: Qualcomm Adreno 510, 600 MHz, RAM: 3 GB, 933 MHz, Storage: 32 GB, Display: 8...

I thought it was Exynos.
[Galaxy Tab S2 Original Android Development] lmacmil:
My T713 had a fit yesterday and rebooted 5 times in succession. Each time I was in a browser, 3 times in Chrome and twice Opera. It had not spontaneously rebooted for a month at least and I use it every day. Oh well.
[Galaxy Tab S2 Original Android Development] kissiel7:
Is there any problem running Roblox on Snapdragon?

I've T813 and exactly the same issue - when starting Roblox it hangs on a white screen (I'm running official LineageOS 17).

Any references to details how to overcome this issue would be appreciated.
[Galaxy Tab S2 Original Android Development] Deltadroid:
Roblox works fine on my T813 running cm-14.1 branch (lineageos). I guess that Roblox has problems with the different Adreno blobs (for the video driver) that are used in Lineage's Oreo and Pie ROMs.

I haven't seen anyone else post it, so I will... I've updated like normal using the updater for the past two weeks, and root does not hold through update anymore. I assume it is because of the changes made to the stable version of Magisk and how root is accomplished. Easy enough to get it working again. After update, Use Magisk Manager to download Magisk .zip only. Shutdown, and then reinstall Magisk with TWRP. I had to remember how to get into recovery last week since root had held for so long.
[Galaxy Tab S2 Original Android Development] Lithoss:
This is probably a stupid question, but is there a way to fix this without rolling back to an older ROM?

Anyone else experiencing severe battery drain on the last few builds? I have to turn my wifi off so it lasts through the night. No new apps or changes to settings in months, just new builds.
[Galaxy Tab S2 Original Android Development] lmacmil:
I am on the January 18 build. I always put mine in airplane mode overnight and lose 1-2%. Last time I forgot I think it lost about 10% but I don't remember if it was this build or an earlier one. I update once a month after the latest security patch gets Incorporated.

Hi guys,

I was using LOS 15.1 and wanted to try this build, cleaned everything and flashed the lineage-16.0-20181009_005544-UNOFFICIAL-gts28vewifi.zip with TWRP 3.2.1-0 but I got the following error:

"Updater process ended with error: 7, Error installing zip file"

What I'm doing wrong here?

Best Regards
[Galaxy Tab S2 Original Android Development] Icewyng:
If I recall correctly, you need to update your TWRP (it is now at 3.2.3.0).

How's battery life on LOS 16.0 BTW?
[Galaxy Tab S2 Original Android Development] 9646gt:
Been using this ROM for a while, and I must say it is amazing how well it runs! This is the fastest and most stable my tablet has ever been. Thanks so much!
[Galaxy Tab S2 Original Android Development] tavcsor:
Usage: 10-15% per hour. It is very similar to stock. Standby: 1-1.5% per our. Much worse than stock. WiFi is not turning off while the tablet is sleeping.

Hi!

Thank you Luk1337 for giving us android pie to our tablets!

I've got the t713 two weeks ago and I installed 9th October version, didn't test too much, everything seems right, but just one thing is not working as expected: changing user from lock screen

Two users on the tablet, to change from one to the other the only way to change is to be on the other's session and change from there. The first user (administrator) has enabled change user from lock screen but the icon on the top right on lock screen does nothing

Anyway we know the other's pin so it's not a big deal in our case to login in the current user to change to the other

Thanks again, awesome work!!!!
[Galaxy Tab S2 Original Android Development] LuK1337:
I disabled it cause Google made it really ugly and I didn't feel like wasting my time on it.
[Galaxy Tab S2 Original Android Development] sbenninger:
Has anyone had issues with WiFi on recent builds? I quite often need to turn the WiFi off and on again for traffic to pass. It is always showing connected but just stops working. Clean flash. Done everything except a factory reset? I tried to flash an earlier version but just got stuck in a boot loop.
[Galaxy Tab S2 Original Android Development] tjupille:
poor battery life [FIXED]

Just about the only problem I have with this build is battery life.

- 44% loss in 24 hours sleeping

- about 15%/hour watching Netflix with moderately dim screen.

I have another 713 running rooted "stock" Nougat, and the battery life with that setup is just about double. Apparently there are some battery life issues with Pie (https://venturebeat.com/2018/11/01/android-pie-has-a-battery-life-problem/); at this point I'm going to revert to 15.1 and see how that does.

Update: 15.1 loses about 0.6%/hr overnight. and 10%/hr running Netflix, so not quite as good as stock Nougat, but lots better than the 10/18 build of 16.0

Update 11/12: I installed the 1108 build; what a difference! Sleep uses about 0.4%/hr; watching NetFlix uses about 11%/hour. Both values are in line with rooted stock. :)
[Galaxy Tab S2 Original Android Development] J_M_H:
Do you have any plans to take this "official"? Thanks.
[Galaxy Tab S2 Original Android Development] DungeonseekerUK:
Suffering an annoying bug that started around a week ago and seems to be getting worse.

I'm currently using to 10/18 build (though im downloading 11/08 as I type this) and after around an hour of use I get a blank white screen that pops up and will not go away until I reboot. If I press the home button it goes back to desktop for a few seconds then the white screen pops back up again, if I press the app switch button then the app switch view comes up for a few seconds before the white screen pops up again, even if I quickly press close all the white screen still pops back up. Nothing I can do except restart gets rid of this screen.

In the switch app screen the white screen shows up as an application and being really quick i was able to snap a screenshot of it including its logo (which I don't recognise)

This bug is making my tablet unusable.

Problems with widgets & device administrator apps

I'm not sure if these are specific to this ROM, or if it's a general Pie issue.

1. Some (but not all) widgets don't work. Their settings show up in the app drawer, but they are missing in the launcher (same issue on both the default launcher and on Nova launcher). Specifically, aCalendar+ and Google Calendar widgets are missing. The default Calendar app agenda widget *is* there.

2. Some (again, not all) apps that need to run as device administrators are missing from the device admin screen in Settings. Specifically, Screen Off/Lock, and Edge Effects behave this way. Greenify Automator *does* show up.

If anyone could try to put a Google Calendar widget on a home screen and report back, I'd be grateful.

Thanks in advance!
[Galaxy Tab S2 Original Android Development] Laz35:
Just tried to place google calendar widget on home screen and it worked without issues. Using Nova launcher btw.

Hi guys I have a t719 and looking at flushing this rom. Does adoptable storage work fine with this rom please?
[Galaxy Tab S2 Original Android Development] LuK1337:
Dunno about you but on my screen the thread name says T713, not T719.
[Galaxy Tab S2 Original Android Development] marvi0:
Oh what's the [9]? I thought that meant either t713 and t719. So do we have one for t719?
[Galaxy Tab S2 Original Android Development] solnyshok:
Yes. I use free app Automate with action to disable WIFI on screenlock, enable WIFI on screen unlock. Otherwise I was loosing apr 4% battery every hour during sleep.

I have been unable to get Google Files to install, even with sideloading it. Anyone done so successfully?? If so, how?
[Galaxy Tab S2 Original Android Development] lmacmil:
That's one way of forcing us into 17.1.
[Galaxy Tab S2 Original Android Development] friedsonjm:
There is no official 17.1 and my reviews of the unofficial thread it seems that it is buggy and infrequently updated. :( ...EDIT: and the last update was 2020-07-14
[Galaxy Tab S2 Original Android Development] RoterfuX:
Hopefully someone will pick up the development. I really like the device, perfect size and it was fast enough for the things I did. The galaxy tab 5e is just to big...
[Galaxy Tab S2 Original Android Development] sliding_billy:
Considering the T713 is a Wi-Fi only home device, I am not really that concerned about security patches. I haven't noticed a feature enhancement in a long lime, and except for the occasional wireless drop (which has existed forever and was never getting fixed) I have no bugs and everything I want to run does so. I will miss checking updater weekly like I missed checking for dailies when it got those
[Galaxy Tab S2 Original Android Development] lmacmil:
There have been updates from both developers this month. Look at post #1 in the 17.1 thread.
[Galaxy Tab S2 Original Android Development] friedsonjm:
You are correct, and I stand corrected. I was looking at the OP, and not the downloads. I just finished installing the 17.1 ROM and am installing apps now..
[Galaxy Tab S2 Original Android Development] lmacmil:
We'll be looking forward to a short review in a couple days! 😃
[Galaxy Tab S2 Original Android Development] lmacmil:
Are you suggesting that used behind a properly secured router and firewall, the security risk is minimal? I hadn't thought about it that way but it seems like a reasonable assumption.
[Galaxy Tab S2 Original Android Development] friedsonjm:
So far, working very well indeed. Seems more responsive than the 'Official' Lineage 16.0 I had to 're-learn' that I needed to use Odin to install the new TWRP! One strange thing, that is the same as I had with 16.0, is that I can't install Files by Google! Won't show on the Play Store, and when I exported the apk and tried to install that, still no dice. Note, I installed ripee's version, from what I can tell he is updating monthly, rather than pitrus's daily updates.

EDIT: Downloaded APK Mirror version of Files, and that installed.
[Galaxy Tab S2 Original Android Development] lmacmil:
What TWRP version did you use? Can't it be updated from within whatever TWRP version is already installed? I'm on 3.3.1-0 and I haven't been able to determine if that will work or if I need a later version.
[Galaxy Tab S2 Original Android Development] friedsonjm:
I used the TWRP that is linked to in the original post, but the only way I could install that was using odin. I do not believe there is any other way to install that twerp and you have to have that TWRP to install these roms.
[Galaxy Tab S2 Original Android Development] sliding_billy:
Exactly
[Galaxy Tab S2 Original Android Development] lloydsw:
I updated to 3.4.1-0 from within an older TWRP
[Galaxy Tab S2 Original Android Development] lmacmil:
I did today also.
[Galaxy Tab S2 Original Android Development] lmacmil:
Thanks. Would like to know what you think in a week or so. FWIW, I was able to update TWRP to 3.4.1-0 from within TWRP 3.3.x.x.
[Galaxy Tab S2 Original Android Development] ripee:
You can still run unofficial builds with the existing 16.0 sources. Lineage will keep pushing monthly security updates to the 16.0 branch, like they do going back even to 14.1.

[Galaxy Tab S2 Original Android Development] lmacmil:
I was referring to an upgrade from 16.0 to 17.1. There seems to be mixed opinions on whether 17.1 is suitable as a "daily driver" or not. I was just looking for another data point.
[Galaxy Tab S2 Original Android Development] friedsonjm:
So, I have had exactly one issue, an unexpected reboot this morning after reading a number of different news sources. I use this table for about an hour each day, pretty much always for the same things. I note that there are two different developers posting in the same thread, one which updates monthly, and one daily. I'm using the monthly update, so it may not have the latest 'fixes' that the daily one does. I will say, I find the new ROM to feel faster and smoother than 16.0
[Galaxy Tab S2 Original Android Development] lmacmil:
I may bite the bullet and install it this weekend. Thanks for the update.
[Galaxy Tab S2 Original Android Development] solnyshok:
there still are new builds of LOS 16 by pitrus.

Sorry to be an idiot. but i've read almost every post in this thread and don't see a guide on the exact steps to do this. Seems to be 10 different ways if you google it.

So I've got 3 SM-T713 and both the most recent 16 unofficial, and 17.1 builds crash randomly when the device gets below 55% battery. Is anyone else experiencing this? Does anyone have a fix?
[Galaxy Tab S2 Original Android Development] martinknl:
Probably caused by battery degredation, our devices are getting old. Fix by replacing battery or keeping connected to powerbank

I have the same when the battery is under 15%. Then any power-consuming task resets the device.

[Galaxy Tab S2 Original Android Development] Deltadroid:
It could be related the Pie branch. Try cm-14.1 branch and see if it still happens.

[Galaxy Tab S2 Original Android Development] fmc000:
Quite strange, even the newest release (T719) still has the Jan2022 security patches even though the changelog mentions that the Feb2022 should have been applied.
[Galaxy Tab S2 Original Android Development] thefanum:
I'm not convinced it's hardware. I've got 3, all good battery health according to the acubattery app, and all of them do this. But please report back if it's a hardware issue and that fixes it.
[Galaxy Tab S2 Original Android Development] thefanum:
Unfortunately no luck. Same issue.
[Galaxy Tab S2 Original Android Development] thefanum:
I've considered that but I have 3 different tablets of this model, all reported as healthy battery by acubattery (not fool proof diagnostics, I know), but every single one of them has the same exact threshold for spontaneous reboots .

I've now tried LOS 14, 16 & 17, on 3 different tablets, and all of them start randomly rebooting below 55% battery (although not always at the same amount below it). What's the next step for trying to diagnose this, if it is a software/OS issue?

[Galaxy Tab S2 Original Android Development] thefanum:
Ok great, thank you. I'll try that also
[Galaxy Tab S2 Original Android Development] thefanum:
Ok, preliminarily, I've had some success already. I installed the app "SmartPack-Kernel Manager" as suggested. I'm first testing on my LineageOS 14.1 nightly (Android 7.1.2), SM-T713. I've applied these settings, and was able to get down to below 5% battery 2/3 times (starting at 15-17%) INCLUDING under heavy load:

Hamburger menu in the top left, select "CPU".

Big CPU: CPU Maximum Frequency: 1382 mhz

Little CPU: CPU Maximum Frequency: 1190 mhz

Toggle the "Apply at boot" toggle at the top of the screen.

Back to hamburger menu in the top left, then 'i/o scheduler":

Internal Storage/Scheduler: set to "noop"

External Storage/Scheduler: set to "noop"

Toggle the "Apply at boot" toggle at the top of the screen.

Reboot the tablet and please report back if it works for you, and also what threshold you had to adjust, if any.

I'll be testing my LineageOS 16 and 17.1 tablets next. I'll keep everyone posted.
[Galaxy Tab S2 Original Android Development] thefanum:
Well, I think you guys cracked the code. I've had success with this approach/settings on LineageOS 14.1, 16 AND 17.1!

All 3 of my SM-T713's now work.

I was even able to do some fairly demanding multitasking, while around 15% battery. Whereas I couldn't even single task without crashes before these fixes.

Now we just need a 18.1 port, and my fav tablet will be perfect!
[Galaxy Tab S2 Original Android Development] lmacmil:
Getting ready to sell my T713. Currently on 17.1 but the camera does not work. My guess is that potential buyers will want a working camera more than a later Android version. Does the built-in camera app work on 16.0? I don't use the camera myself so I don't remember from when I had LOS16 installed over a year ago but I do remember reading that it did.
[Galaxy Tab S2 Original Android Development] thefanum:
I had not previously tested the camera (as I don't use them on tablets), but I just did a test on both the newest LineageOS 17.1 and the Feb 14's build of LineageOS 16.0.

As you mentioned, it's completely non functional on 17.1, but it does work on 16.0. Both cameras tested, and took "acceptable" quality photos (significantly worse than a newer device, but within the range I would expect from a device of this age).

Hope that helps!
