Sry but I don't understand what you cant to say with "an automated auto clicker".

So it's definitely not possible to use an old gpu driver on oreo and sup.

I think the only solution is to port the sprd adf (atomic display framework) driver to replace the framebuffer driver and after maybe we will able to use the new sprd mali driver for and8.1 based on adf.

Framebuffer driver is completely deprecated.

... but it's very hard ... I have some versions of the sprd adf driver, an old for our kernel and a new for the kernel 4.4 so it's possible but very hard.

Changelog

Can you please please make a change log on update and show the differences and update between the previous version and the latest update version.As in some cases I have noticed there is a big difference and some there is no difference to feel.

I would kindly request for a Change-log ,

Thank you
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] djeman:
Pff it's not easy to make a changelog, you have the git if you want to know all.

On the latest I enabled call recording, applied the september security patch and I tried to fix some cve on the kernel ... 82 :x

Kernel changes => https://github.com/djeman/android_kernel_samsung_j3xnlte/compare/9c3196f528bd...1b629683a396

On the version before the latest I fixed a big problem in the jelly brower when you close a video.

And some others things not visible.

I've only few questions/doubts about flashing this rom:

1) I can install and use Samsung Apps? So Samsung Apps can recognize the Smartphone like a normal Samsung device?

2) I've try to flash by Odin this rom, but I cannot install a Recovery because i've the FRP block enabled, There's a guide to unblock or disable this FRP?

In headphones or on speaker? in headphones there is a small problem, when you increase the volume from the standard position the sound is no longer linear, where you need more power as for low frequencies the volume is lowered to avoid audio distortion. probably this rom (and not only this) allows you to increase the volume beyond what the hardware of this device is capable of doing.

In fact for example if you try viper os when you increase the volume from standard position the sound is distorted.
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] 2gg1:
I also think its a system bug its on the speakers. Do you know that weird distorted sounds from cheap earbuds when you plug them in? I got that sounds randomly when i am watching youtube or something else with sounds. I am going to try reflash this rom. If its still happening i am going to try flash stock rom. Because all hardware are compatible with that rom.
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] MR207:
may depend on the damaged speaker, this rom compared to the original firmware has more powerful bass and the speaker of this phone in theory is not designed to support too low frequencies. In fact if you restore stock firmware the sounds are more acute, the low frequencies are cut off. if the speaker is slightly damaged, with high volume, normally the sound comes out distorted.
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] 2gg1:
Ok, i'm going to look at it. Also thank god that speakers arent expensive for this phone. ?

Edit: Besides problem with audio, my simcard doesnt get detected sometimes. ??

Hello I installed last lineage version avaiable in the first page and have big problems with a vodafone sim: data connection often doesn't connect: and if doesn't any connection data (but at least gsm connection), i can't receive any phonecall. The strange thing is that i have tried to call my number with another phone and the result is that i can hear the ringing tone in the second phone but in the j3 i cant se any incoming call. Isn't a reception problem because if i turn many times the phone in airplane mode, at the end the phone can able to connect at data connection. What can i do? I done all the possible to assure that isn't a vodafone problem: i changed my sim with a new one, called the assistance but nothing. And if i put a sim in another phone, there's not this issue. I have another sim installed in the second slot , branded "Wind", that not have this issue. Maybe the type of connection isn't compatible with this phone? or this rom?

Thanks

Edit: i have tried now to leave only the vodafone sim, removing that "wind" one, and the issue is DISSAPEARED! so there is a conflict with two sims connected?

This twrp is not really tested, I changed recently the android binder driver.

So now the encryption seems to work but to use it you must to format the data partition (internal memory is on data partition) with the new twrp recovery.

You can backup and restore data on the new partition and for the internal memory a copy on the pc.

When the phone is crypted the only way to disable crypting is the full wipe option in the twrp when you need to write yes.

[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] djeman:
[MENTION=6061403]PuYaU[/MENTION]

Yes for now ... but you cannot format a partition to f2fs.

The encryption on los15.1 have a little difference the footer reseved space is allocated automatically by the framework so the option to reserve space is useless.

For this reason mkfs.f2fs can't reserve 16KB at the end of the partition (option -r removed in the soft).

https://github.com/djeman/android_d...mmit/43ac7d5b40d9c6f639846a02f4cebd452ab82972

The length parameter is an error on los15.1 but it's needed on cm14.1.

15269887 - 15253503 = 16384 = reserved memory for the footer encryption

[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] LPW00:
Hi. After the very painful process of rooting a Samsung using a Linux PC, I finally managed to boot this ROM. And while sure, 7.1.2 is close to ancient as well, it's a very noticable step up from 5.1, especially since touchwizz is a pain in the bum. So thanks to everyone involved with Lineage and especially to those who ported it to this device.

Though I do have some issues that i want to adress.

A) MTP seems to be borked. It doesn't show all my files on pc. To be exact: mtp:/SM-J320F/extSdCard/ and appears empty apart from the Android-, Music- and LOST.DIR-folder and stuff i move there via PC shows up too. The other files and folders don't show, though they do exist and are accessable on the phone itself.

B) I made a screenshot and when i tried to copy it to my PC it shows as corrupted, I am able to upen it on the device. This might be related to A).

Those two are critical, now nitpicks:

C) The Backlight option for hardware keys seems a bit stupid on a phone without luminous hardware buttons

D) Since adaptive brightness isn't an option the text in the settings under "Display" is useless, it might be worth it to let it say wether or not Live Display is enabled.

Since it's an amoled, u could enable Always On Display btw. i think it's just a flag or something.

Is this ROM still in active development?

When you flash must be a clean flash you must wipe cache dalvin cache system and data after this flash the rom
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] Tommytommy1234:
A, B) MTP works fine for me. Maybe you done that but I need to ask, you enabled android debugging in developer options right? Try to turn off the phone, remove sdcard, boot up and then add sdcard again and connect to pc.

D) I guess AOD is Ambient display, so check this one.

And unfortunately, I guess this isn't maintained anymore.
[Samsung Galaxy J3 (2016) ROMs, Kernels, Recoveries] LPW00:
This is almost insulting. I'm not that dumb. Not even I would flash Lineage 14.1 over Lollypop 5.1 Touchwizz.

Yeah, ADB was actually enabled by default

That surprisingly worked. This is my first phone with SDcard support since my very first phone back in the days (Android 2.3.6), and I didn't know what custom ROMs were back then.

nope, that's something else

R u certain about that? Maybe [MENTION=1619533]djeman[/MENTION] is still working on updates? 25th January was not that long ago. I mean long enough to raise my suspicion, but I've seen projects with longer breaks *cough* Paranoid Android *cough*.

Thing is, I found a real bug this time. Install (I guess) any Substratum theme (I obvsly didn't try every single theme out there) and when u long press the power button to bring up the power menu, the phone soft reboots.

Also the settings app needs a really long time to load after booting, same goes for the launcher I installed. (We had this bug too in the early days of Nougat on OnePlus One, but it was fixed rather quickly, I bet that fix is still somewhere on GitHub, I might dig it up if there's any hope for the J3 ever getting an update again.)

I don't use themes, only the stock one(which works perfectly fine :D). I changed the drawer to compact to make it more "comfortable" and its ok. If you like theming, lineage is not kinda your best bet, should flash something like Resurrection Remix(I used it some time ago and was pretty nice, lot of customizations, not updated like this one but good enough). And I recon djeman is not maintain this rom anymore because in the past, he was active and he said he will sell his j3 after 2019.

Anyway, it's pretty impressive to have a such phone with better security updates than 2017-2018 phones :) so I guess it's really nice even if we will not receive any updates. Did you had/used one plus one?

The free space in the internal storage isn't that better. At least you can win 500mb, because the lack of bloatware. If you really want to squeeze the 8gb of the j3, you will probably need to modify the partitions, specially the system partition.
