Forgive my ignorance, but when you say "delete the app", is it an apk somewhere? I'm not sure how I would do this. It's not a GAPPS install, and I looked around TWRP File Manager, but don't see anything apk related. Some other things I read was that there was a facelock.apk, but that might be old data.
[Galaxy Tab 4 Android Development] DJABHipHop:
facelock.apk is is the one

[Galaxy Tab 4 Android Development] DJABHipHop:
a?
[Galaxy Tab 4 Android Development] matteo0026:
Probably. PM me, here or in telegram, I have to ask some things to you. If we want to check the support (init stuff must be adapted surely), we have to check if this variant can handle custom software, by starting from TWRP.

Hi, just got 1 question..

I get a SM-T533 just today with stock 5.1.1 and want to flash recovery and update rom 17.1 but why there isn't rom for my model??

Do I have to choose matisse wifi one or no???

thank's
[Galaxy Tab 4 Android Development] DJABHipHop:
Sossy, But your device isn't supported.
[Galaxy Tab 4 Android Development] matteo0026:
Your device has msm8916 soc, which is completely different from us (starting from telling that has a 64 bit CPU). Then, we can't support it with the other matisse/millet variants. Its codename is matissevewifi.
[Galaxy Tab 4 Android Development] rayman95:
thank's for the answer...so do you know which last version is for my device???

thank's
[Galaxy Tab 4 Android Development] matteo0026:
I think staying in stock ROM is the best choice

Maybe somebody can help me out. I've installed this rom and on my tab t530 and it's working well.

The only thing i've encoutered is the camera access from a app called 'Fully Kiosk Browser & App Lockdown'; which enables users to use their tablet as a kiosk.

In this app there is 'motion detection' via the frontcamera to turn the screen on. The app works with te camera, but sometimes it hangs and it's trying to restart the camera. I already contacted the app builder and they are saying that another app is trying to use the camera, or there is some underlying OS problem. I do not seem to get this debugged. I noticed that every other ROM I tried is having this problem, except the original Samsung one. Does anybody have any tips/tricks for me to sort this problem out?

I've trid Android Studio Logcat to view the error; but all i get is:

why is this rom so slugish. i know its a 6 year old device but the lineage 16 rom is so smooth and runs with no lag but this rom is SO laggy. my tab 4 is a 10.1 sm-530
[Galaxy Tab 4 Android Development] DJABHipHop:
I'm trying to fix it meanwhile you can delete the faceunlock apk
[Galaxy Tab 4 Android Development] DJABHipHop:
Anyone using Q can delete the face unlock apk
[Galaxy Tab 4 Android Development] JonneTukiainen:
Ok. Also great work on supporting older devices and keeping them alive :good:
[Galaxy Tab 4 Android Development] Karbohydrates:
I can confirm this happens.

This can happen in any app, but in my experience, it happens whenever I need to check my notifications, most notably, while using Google Chrome.

It doesn't always happen, but when it does, the screen briefly goes black, and then makes me unlock the device again.

"Tap to sleep" is disabled.

Hi everyone, noob question:

Offline charging not working. Does it mean that if battery is drained and tab has not enough juice to boot I will never be able to use it again ?

Thanks a lot.
[Galaxy Tab 4 Android Development] DJABHipHop:
Well it should.
[Galaxy Tab 4 Android Development] matteo0026:
Which variant do you have? Anyway, battery should charge the same when it's at a low level. It's not the best thing to test it, by the way. I've never tested it.
[Galaxy Tab 4 Android Development] LivArt:
You can plug in charger, boot into download mode, let it charge there and then you can turn it on. I have tested this way.

Family link activation problems

I've downloaded and installed the latest build on Matisse WiFi.

The speed on UI navigation is astonishing.

I tried to set this device up for my child using family link but am getting stuck with an error

-"This family link manager is required for Google accounts managed with Family Link".

Had anyone run into this issue? And is a solution available?

I have now formatted the system, data, cache and internal storage, then installed the ROM + nano Open Gapps to see if that works eliminate the issue but without any joy.

In order to install other Apps, I tried to download all files using the browser but to my surprise I can't download any APK on the browser either.

I'm sure I'm doing something incorrectly so I'd be much obliged for the help.

Thank you.

Did you save the rom to sd card? If you did try saving it to the internal memory via TWRP connected to a pc
[Galaxy Tab 4 Android Development] Scepterus:
has anyone managed to create a widget to the saved network menu or found another solution to not connecting to a hidden network?
[Galaxy Tab 4 Android Development] Buxi78:
Hi,

i´ve got a problem to activate the family link manager on a my galaxy tab 4 10.1 (SM-T530) too.

I successfully installed this ROM: "lightning-17.1-20201108-UNOFFICIAL-matissewifi-Unsweetened-XDA-BUILD"

and

this gapps package: "BiTGApps-arm64-10.0.0-R11_signed"

It works fine and when using it with my google account i even could install the family link manager for children.

No my problem is the following:

To use family link for children i must delete my google account from the device and add the google children account of my daugther.

In the setup-routine for the google children account i can add her account succesfully and in the next step i could give my "parent permission" for activating her account on this device too. Then the step follows where i can setup the data security settings for this device. After that the Screen shows as next step "activating family link-manager" with a forward button. When i push this forward button this message is shown in a pop up window: " this profile manager is required for google accounts managed with family link" . Then i only could confirm this message with "ok" and the screens wents back to step "activating family link-manager" where i only could push the forward button to get the same message again "this profile manager ... ". It´s a loop and i can´t get into the next step.

Does someone has an idea what i could do?

I thank you in advance for your help.
[Galaxy Tab 4 Android Development] sammy2332:
Hello.

I have model TM330NU - will my tablet work with this ROM ? I did see that the 8" tablet is supported but it's not clear to me whether it's all models.

If so, can someone direct me to instructions on how to install this on my tablet? I've already backed everything up. I haven't done any custom rom installing in a long time (last was maybe a PSP, Iphone 4, ipods, nintendo 3ds) so what I'm seeing on the front page is confusing to me.

EDIT : I did some things and I added info below

Also, as I'm mainly interested in reading on my tablet and the occasional browsing and youtube viewing. Can someone confirm whether any of these apps work ? ( I saw that some apps require a certified device, like Netflix, but I don't know how to figure out which apps need a certified device)

- Google Play Books

- Kindle App

- Youtube

- Amazon Prime Video

- Spotify

- Dropbox

- Google News

- Google Drive

- Google Photos

Not all of these are absolutely necessary, but it'd be nice to know what I'd be sacrificing if I do this.

Any advice would be greatly appreciated. Thanks!

EDIT :

So I downloaded :

ODIN 3.10.7

TWRP 3.4 .img

TWRP 3.4.tar

the lightning build (a ~400mb file)

samsung drivers to make ODIN work

magist v18.1.zip

I've so far been following the instructions here

https://odindownload.com/root-android/

and I installed TWRP using ODIN and Magisk using TWIRP. Now what's left is the lightning build and the gapps.

So my new questions

1. Are the instructions in the link above appropriate for installing this build ?

2. If so, do I need to go buy a microSD card or can I just use the internal storage to store this build file ? If so, how big of a microSD card ?

3. What backup do I need to do besides the files/media on my tablet ? If there's anything - how do I do it ?

4. After I installed Magisk - my tablet is stuck on the samsung animation logo. What's wrong ? Is this because I selected the option for it to reboot itself when installation is complete ?

EDIT 2 : I rebooted and still the same problem. But I was able to get to the TWRP recovery screen.

5. Where do I get gapps from and how do i install that ?
[Galaxy Tab 4 Android Development] matteo0026:
Magisk 18.1 is too old. Get the latest build from github page of magisk. Gapps are in opengapps.org page. You have to get arm 10 pico package. About the instructions, follow mine in los16 thread
[Galaxy Tab 4 Android Development] IamTheBRAVE:
Hi, not an expert on this, but it seems to me like all accounts on the device will have to be family link google accounts. So you'd have to create one for yourself too, have you tried that?
[Galaxy Tab 4 Android Development] Buxi78:
Hi IamTheBrave, thanks for your answer.

But sadly that wouldn´t work. To activate a childrens account, all other accounts on a device must be deleted. When i add my childs account to the device it automatically knows that this account is a part of my family group and then i had to give my permission through tiping my password into a pop-up window.

Normally the family link manager should start in the end of the above written steps, so that the last settings could be done. It seems as when there is a communication problem between the google child account assistant and the familiy link app so that the command to start the app is not executed.

By the way. I wish you a nice 3. Advent.
[Galaxy Tab 4 Android Development] sammy2332:
Thanks for the reply and help so far! I downloaded the gapps that you recommended and magisk 20.4. I looked at the los16 thread on pg 1 and honestly the instructions aren't any more clear than the instructions on this thread. Are they on another page ? There's 15 pages there if you can link me to them - that would be really appreciated.

So my remaining questions now are:

1. Do I need to go buy a microSD card to store the build file or can I just use the internal storage to store this build file ? If so, how big of a microSD card ?

2. What backup do I need to do besides the files/media on my tablet ? If there's anything - how do I do it ?

3. After I installed Magisk -(18.1) my tablet became stuck on the samsung animation logo. What's wrong ? Is this because I selected the option for it to reboot itself when installation is complete ? How should I install the 20.4 version now ?
[Galaxy Tab 4 Android Development] Jura_ZG:
Hi, i flashed the latest rom but I'm having issues. I had dirty unicorns before but it suffered from a really poor performance. I updated TWRP to the version recommended in the first post. Then flashed the latest rom for T330. Unfortunatley I have issues. System UI seems to crash. Frequently apps crash. Keyboard takes forever to pop up (sometimes it feels like it plays with me, poping up for a second and then colapsing). Is thre something I can do? I already did a factory reset after I flashed the rom.
[Galaxy Tab 4 Android Development] matteo0026:
Factory reset isn't enough. You have to do wipe data, system, cache and dalvik before flashing ROM
[Galaxy Tab 4 Android Development] Jura_ZG:
I thought so. I wiped cache and data, wasn't sure about the system. I'll do it again. Tnx for the help. Cheers!
[Galaxy Tab 4 Android Development] Jura_ZG:
Well, it didn't quite work out. All seems like its ok but for some reason apps tend to just close on their own. Any app basically, youtube, google store, etc. There's no popup error, app just closes and device is on home screen. Any help with that? I quite like this tom, its fast and responsive but apps random closing is something I can't live with.
[Galaxy Tab 4 Android Development] matteo0026:
Ok. Try my ROM, LineageOS 16.

A lot of people is attracted from this ROM because it's the only based on Android 10, but it isn't the most stable one...
[Galaxy Tab 4 Android Development] Fredfj:
I installed lightning-17.1-20200628-UNOFFICIAL-matissewifi-Unsweetened-XDA-BUILD on my Galaxy SM-T530.

Everything is working wel except the micro SD card. I only can use the card for Portable storage. When I select the other option -Tablet Storage, then the formatting crashes. There is a short moment an error message, but to short to notice the text. When I select portable storage for the SD card everything goes well.
[Galaxy Tab 4 Android Development] Jura_ZG:
Tnx mate, worked like a charm. No more random app closing and hick ups. Cheers!
[Galaxy Tab 4 Android Development] IamTheBRAVE:
Would it be possible to install a gsi over this rom? I'm thinking of this :

https://xdaforums.com/t/gsi-11-lineageos-18-x-gsi-all-archs.4205461/

My T531 is starting to show some weird behavior after installing the last update. (Mobile data keeps crashing, then tab powers off and reboots to recovery).

I haven't used this tab as much as i used to because of the instability. Hoping for a better update in the future...
[Galaxy Tab 4 Android Development] matteo0026:
No, it isn't possible. We don't support gsi. I know that matisse3g has issues with RIL, but I don't know how to fix it.
[Galaxy Tab 4 Android Development] IamTheBRAVE:
Thanks, i thought so. Maybe use persist.radio.noril=1 in build prop? I used to have it added as init.d in 7.1.1 rom but lightningfastrom has secure selinux and won't use init script. Not sure it would work though. It could also interfere with wifi networks?
[Galaxy Tab 4 Android Development] matteo0026:
Init script is used, that noril prop hasn't to be used. It doesn't interfer with wifi networks
[Galaxy Tab 4 Android Development] cali.s:
rom run pretty good for me, waiting for further updates or if possible LightningFastRom-18.1 :)

[Galaxy Tab 4 Android Development] mrk2815:
so is there a lighting 18.1 rom an what gapps are you using.as there are no android11 arm gapps that i am aware of at the moment. if there is then that's interesting news. Also when i have some time , i will flash the 17.1 to se how well the camera works on millet wifi sm330nu.
[Galaxy Tab 4 Android Development] IamTheBRAVE:
I was gonna ask the same question, cause i found this rom which is for the T525. It has a nearly equivalent specs as the T535/530. According to treble check, T531 (my device) is not compatible. I heard there are two versions of treble check and one gives wrong info. Would love your opinion on this, guys.
[Galaxy Tab 4 Android Development] cali.s:
Flashed dirty over the last Rom looks good so far, thanks

@mrk2815 this is lighting 17.1 you can use open_gapps-arm-10.0-pico
[Galaxy Tab 4 Android Development] mrk2815:
will take a look and flash on my millet sm330nu late on.
[Galaxy Tab 4 Android Development] Nukafire:
Honest question here, will other sizes of this tablet be supported in this at a later date by chance? I have a SM-T230NU and as far as I can tell there is no work ongoing anywhere besides here for getting any of the Tab 4 tablets on a newer version of android. I have found the other threads around that are basically just android 4.4.4 with a skin to look like android 7.1, but alas the apps I used are no longer supported and would like to get some more life out of it if possible.
[Galaxy Tab 4 Android Development] DJABHipHop:
Sorry, But not really because they do not have the same CPU.
[Galaxy Tab 4 Android Development] Nukafire:
That's a shame to hear but thank you anyways.
[Galaxy Tab 4 Android Development] Koicarpkeeper:
If you have Google Chrome installed and you do a dirty flash does it keep all the tabs that you had open the last time you used it, or do you end up losing them?

I'm running an early version of this ROM and keep putting off updating because I can't find an answer to this question.
[Galaxy Tab 4 Android Development] cali.s:
idont use Chrome but dirty flashing dont touch user data and apps,

make a backup in twrp and try :)
[Galaxy Tab 4 Android Development] DJABHipHop:
Yes it will
[Galaxy Tab 4 Android Development] Koicarpkeeper:
I made a TWRP backup as suggested.

I was offered 3 backups once the updated system started up and without really thinking it through I skipped them thinking I just want to use what I had open before the update.

Well the dirty flash went perfectly and it was nice and responsive but I had none of my apps installed.

Tried restoring the backup using TWRP but that just gets to the Lineage screen with the connected blue dots and never gets past that point.

Going to try a second flash and hopefully I will get my apps back.

I had hoped the TWRP backup would have just allowed me to go back to where I started from but unfortunately not.
[Galaxy Tab 4 Android Development] BeeJ1109:
Did you do a full backup of all partitions.

If so,, you could have restored back to the original, with all apps functional.

If not, that is why you do not now have any apps installed after flash.

Moral of the story, ALWAYS do a backup, before making changes or reflashing. Backups allow full restoration, back to where, you originally were. Then try flash again, Restore takes a minute or two. Whereas reinstalling apps can take hours or days, depending on no. of apps previously installed.

Cheers
[Galaxy Tab 4 Android Development] Koicarpkeeper:
I did a full backup, that is what is so annoying because when I try to restore it the tablet gets stuck at the blue dots and has been sat there for hours.
[Galaxy Tab 4 Android Development] BeeJ1109:
Suggest you try to wipe everything, except ExtSDCard using TWRP Restore, then reflash your Full Nandroid BACKUP . Then return to TWRP and install the attached fix_rootfs_label.zip from ExtSDCard that you have previously saved.

See if that fixes your problem. Similar problem with LOS 17.1 on I9195 S4 mini ROM restores. Dev is arco68. Bootloops occur after restoring ROM.

Cheers
[Galaxy Tab 4 Android Development] Koicarpkeeper:
Thank you I will give that a go.

Currently charging the tablet after it went flat overnight while bootlooping, even though it was plugged in.

I've also got an S4 I9195 to flash so will keep the file for that as well.
[Galaxy Tab 4 Android Development] Koicarpkeeper:
I'm very pleased to report that worked and my tablet is now back to where it was a few days ago - sort of. I don't know whether flashing that additional file worked or whether doing a full wipe in TWRP fixed it because I did both before rebooting the system.

While all my apps are back and Chrome has all its tabs as I left it there are no files on the tablet in the download folder so I have lost everything on there, even though I ticked everything when making the nandroid backup.
[Galaxy Tab 4 Android Development] BeeJ1109:
Great news that you got it back working again.

As for lost files in download.

If you are using Magisk, there is a fix by adding a module, called TWRP HELPER V1.0

What that does, is adds download and pictures stored in internal memory to backup everything in Data. So when you restore that internal partition, everything is available, as before.

Note there is a different label on data (incl.storage). When you "Select Partitions to be Backup" in TWRP Backup.

Check out Magisk Modules in Download, select and install.

These modules will be permanent until you remove Magisk or update. Just re-install modules again.

Cheers
