V16 Android 9 Pie from matteo0026

V17.1 Android 10/Q from DJABHipHop

(I hear Android 11 may be in the works later on)

I personally use 17.1 on my Tab 4 8" wifi, only as I like the absolute latest, but v16 may be more stable???. (I briefly used 16, then found 17.1 and switched, both seemed perfectly fine.)

Both are a work in progress, so don't expect perfection, but are very usable, and "stable".

I think these two developers do fabulous work on these devices. So I am not saying one is better than the other. Just a matter of preference.
[Galaxy Tab 4 Android Development] BeeJ1109:
Hi Matteo,

Thanks again for your thoughts and suggestions.

1. I will further examine the camera issues. Again Stock works Great. So suggest try to install the Stock Camera App. Called Samsung camera 2. But maybe imbedded in Stock as a standard requirement for each device. May require extraction. More research required.

2. Keyboard is an external app, same As Google keyboard, and the user can select which style you what to use.

I prefer the Standard Samsung Stock Default keyboard, being a Standard QWERTY Layout. Same as Millions of PC keyboards. More options, like back, forward cursor keys, not available on ANDROID ASOP layout.

Explains why so many spelling errors within posts. To hard to to backspace and correct.

3. Again new Folio 360° cover works great on Stock on same Tab4 8.0 T330 . Magnets (10mm round) are at Screen top on LHS, 25mm from Top edge. 35mm in from folded edge on inside on RHS, when Front cover opened.

Cost was $A 9.95 on Ebay. Also same available for Tab4 1O.1, even less around $A 5.00.

5. About moving Apps, your thoughts are irrelevant, (no offence intended) in that ALL Stock ROMs allow move without apps, "Move button" appears on ALL apps under Settings ☆, then select Apps, to see list of ALL installed.

If Stock Android does not allow move, button it is "greyed out".

But using APP2SD app, allows automatically, instead of one at a time, select ALL TO MOVE, very easy to use. Frees up internal memory.

I have some 190 apps installed that takes a fair amount of available memory space. Even on my 64 MB T-835, yes, plenty to spare, so why not, but my i9195T is only 8MB with about 20 apps is almost running out internal memory.

My Observation this Option is Missing from ALL CUSTOM ROMs, I have tried.

Again my thoughts, everyone may agree or disagree. Not a big deal.

Can anyone please provide me a method to extract files from STOCK ROM, without ROOTING DEVICE. Using ADB commands.

Cheers

[Galaxy Tab 4 Android Development] matteo0026:
Moving apps to microSD has been removed with Android 6 (Marshmallow) if I'm not wrong, because Google didn't want users blamed their smartphones to open and use apps slower. So, of course, custom ROMs don't have this feature in because has been removed from Google many years ago and I don't know if there's a Lollipop (cm-12.x) custom ROM.

Anyway, do what you want with your device, I don't want to put Samsung proprietary apps into system. Probably it could be possible, but it's likely a dirty job.

To extract stock ROM files, I advice you to take stock firmware and extract it, until you arrive to extract system.img.
[Galaxy Tab 4 Android Development] BeeJ1109:
Hi Matteo,,

I think you are misunderstanding my comments.

Yes, you are correct Android 6 changed, under the guise of security, to prevent apps to be moved and stopped users from write access to Ext SD card.

So mods were created to fix this issue, by rooting the device. Adding extra lines in platform.xml file, restores Read/Write access back to ExtSD Cards.

So much flack came from users. How dare Google take away functions that was working. Restricting the access was fixed, after Android 8 onwards on ALL future Stock Builds, from all manufactures, using Android OS. Probably worrying about losing Market Share to Apple.

As I have previously said Android via Google has restored R/W access, but not "move apps" in Custom builds at this time.

But someone no doubt will work it out, eventually.

As for expecting you to modify Your ROM builds to add Samsung proprietary apps. Not requesting that at all.

I would just install apk , just like any other app.

As for extracting system.IMG from Stock firmware, no issues. Thanks for the hint, how do I extract files from this image.

I did some programming courses 20 years ago, so I am a bit rusty. But building Apps and ROMs is something I have not studied, but willing to learn.

Things were so much different, when I was your age. I built Guitar Amplifiers similar to 100w Marshall Amps, using Vacuum tubes, called Valves , before Power Transistors, then Power ICs that Rock Bands used in late 60's thru 70's. Still being preferred today.

Mobile devices are relatively new, when I started building Analogue Mobile Base Stations back in 1987 thru to 4G until 2013.

So thanks for your support in keeping these OLD devices still current.

Cheers

At least the tablet has rom support. not all tablets, have rom support.at least these two developers do a excellent job keeping the tablet alive with roms an security patch support. both developes, keep it up.

Samsung SM-T535 Firmware Installation

Hello! :)

I downloaded this forum thread first message the firmware on my Samsung Galaxy TAB4 SM-T535 device.

I have a poor command of English and it would be easier for me if someone could give me a link to a good video where this update will be done?

Could someone help me with the installation of this firmware or look for me some good video where this is all done right?

This is my first time installing this type of firmware. I'm really interested in this topic! :)

Did I understand correctly that this is the Android 10 open source version?

I apologize for any misunderstanding caused by the google translator.

Thanks! :)
[Galaxy Tab 4 Android Development] appye:
So I have been playing with this for the last day or so and it like what I am seeing. We have android 10 on this old tablet running much better than expected! My only gripes would be the camera issues (of course), and the absence of the little arrows (or triangles) that would light up when there is upload or download traffic ...

... Are these known issues related to what I describe above with the wifi icon? Is it the "not very useful" feature that was removed, or is it related to the "Wi-Fi display" issue? ... Is this just some theming issue that is causing the arrows not to be visible? Perhaps someone can point me to an app or something lightweight that can substitute for this?

Does Magisk still not work? It would be nice to make some modifications with root, rather than having to resort to other methods to do system changes. I want to remove the camera app, for example.

I wholeheartedly agree! Excellent work guys!

... Does this actually work, using the old original camera apk? If so, I might have to hunt that down. I notice that the AOSP camera works but is very buggy, sometimes not even saving the file. Open camera is better, but has the same issue where everything is dark. I notice that the rear camera is working, it just seems that it does not adjust exposure either darker or lighter, as it would work reasonably well outside in daylight, but does not work very well indoors. I also noticed that video works fine, adjusting on the fly for brighter or darker environments. Only the rear camera photo function seems to have this feature broken.

DJABHipHop what is the latest version of the rom also can it be updated with an ota function or not. .
[Galaxy Tab 4 Android Development] DJABHipHop:

[Galaxy Tab 4 Android Development] mrk2815:
DJABHipHop are you working on reworking your 16 and 17.1 roms. Will you have your roms for both 8.0 and 10.1 for tab 4 tablet. if so i can test the 8.0 wifi sm330 nu tab 4 8.0 versions of your roms.
[Galaxy Tab 4 Android Development] DJABHipHop:
Nope just 17.1 really
[Galaxy Tab 4 Android Development] William990:
Hello,

I tried to install the ROM on my SM-T530, I started from the Stock ROM I installed the TWRP 3.3.1 and from there flashed the ROM downloaded from the link (version 17.1), but after it has finished the flash it restarts and remains on the logo for a few minutes after which it automatically restarts in recovery by itself. Any suggestions please? Thank you.
[Galaxy Tab 4 Android Development] Advanced07:
Hey, in was wondering if you could make a 100% AOSP rom for this device, i understand you want to personalize it but I don't think this device can even handle anything other than a completely clean no bloat rom. Btw nice job on getting Android 10 to this device :) I can't help you with coding unfortunately but if you want me to test anything i can do it.
[Galaxy Tab 4 Android Development] DJABHipHop:
That what i'm doing debloat LineageOS by removing Useless Features, Apps, Tweeks, Settings, Ringtones, ETC & Simplifying the UI by hiding features on low ram devices like ares.

Second LineageOS if way to bloated, But it is compatible more devices then AOSP, But AOSP is to plain, But it is compatible with all devices, I want my ROM to be in the between LineageOS & AOSP a golddy lock rom, not to many features apps, & tweeks & not to little features apps, & tweeks a balanced ROM not so bare or bloated.

Also personalize is good when done correctly by thats I mean exposing the battery percentage toggle, lock screen shortcuts, ETC.

So if I install this rom and if my device drains completely I wont be able to charge it again? Also how long battery last compared to stock? Does the apps crash? I am using my tablet for internet and youtube only and Im looking if there is a better rom than stock out there because mine started to freeze recently.
[Galaxy Tab 4 Android Development] bobe83:
go to opengapps and download ARM--10.0---pico.

flash the rom and the opengapps after. and at the end dont install twrp as system app.

[Galaxy Tab 4 Android Development] mrk2815:
so what's the correct way to install this one.do you first boot twrp, then install rom then reboot to recovery an then install open gapps pico and then reboot as root is not working for the build.Is that correct. i can deal withthe few bugs as long as hte build is almost stable. will there be aa new build soon or wht hte staus on teh development of he rom. Just wondering.

---------- Post added at 06:36 PM ---------- Previous post was at 06:29 PM ----------

Is root fixed in the mar 20,2020 build or should one wait.i do want to have root as well.so that is why i am asking about all . i can wait a bit longer if that means i can have a better experience out of the rom.

Hi guys, I'm trying to install the lastest build (lineage_17_1_20200321_UNOFFICIAL_matissewifi_Unsweetened_XDA_BUILD.zip) of LightningFastRom on my SM-T560NU and It keep reboot to recovery.

(I was on Lineage 16.1 before)

What I did :

Boot TWRP 3.3.1.0 into recovery

Backup of my previous rom and

Install the lastest build with the lastest Gapps (ARM, 10, Pico)

Wipe Data, Cache and Dalvik and reboot the tablet.

What's wrong? Anyone else having trouble to install it?

Thanks
[Galaxy Tab 4 Android Development] R0kiss:
Thank you for fixing magisk!

Now that there is root I've tried to edit mixer_paths.xml file, which is now located root/system/vendor/etc/mixer_paths.xml

I've tried couple file explorers and gave them root access but cant save edited file. File permissions says it's readable and writeable. I can't even delete the file. Tried with selinux mode changed to permissive, didnt help. Twpr file manager doesnt show any files in /system folder. So how do I edit it?

SCREEN MIRRORING function does not work

I found the solution to this problem:

SCREEN MIRRORING function does not work

Steps:

- Go to /system/

- Open the build.prop file

- In the last line write: "persist.debug.wfd.enable=1"

- Reboot the system

Testing completion:

Android 9

Worked perfectly

Android 10

The options appear, but the device restarts when selecting the TV to mirror, unfortunately it did not work.

Who can test, thank you

[Galaxy Tab 4 Android Development] appye:
Okay so the arrows are there then, just themed the same color as the icon? Is it a difficult thing to be another theme? Or go back to also or li eageos theming? Perhaps delete a folder somewhere?

So far so good on your rom, the only other thing I noticed is that the timeouts(?) for long press on the hardware buttons is too short for me. Tapping the back button brings up the history menu on my browser, for example, as if I had held it down. Is this something that can be modified with a config file somewhere?

Which TWRP do you have? If you don't have my latest TWRP, then flash it.

And flash latest build, not that 28/06 one.

Djab isn't caring enough about users support, so I have to double my work... I can tell you that the issues that you can read on my LOS16 thread are present in this LFR17.1 too. Then, if you need SIM, flash stock firmware with Odin, for now. As every other issue, it needs some time to be debugged and fixed. I have other testers that are working with me yet, but the issues are many and I don't have other people to base on to do this work.

with the fact that the thing cant go from charging to file transfer.have people changed default USB to file transfer in developer options, and that way being able to go from charging to file transfer.as i recall that has been a bug with most android 10 custom roms an the work around is to go into developer options and change the default USB to file transfer.
