Samsung's source code for Exynos is both dated and incomplete. Making AOSP or LineageOS ROMs using the source code is difficult. So difficult in fact that many developers stopped developing for Exynos devices altogether. So Exynos is a bad choice if you want AOSP or LineageOS. That is why the bulk of the custom ROMs for Exynos are Touchwiz ports.
Making a device for Qualcomm Snapdragon processors is far easier, as Qualcomm provided all the source code for the CPU. Since all the source code is present, an AOSP or LineageOS ROM is that much easier to build.

I don't think the problem is about our exynos CPU.
galaxy S5,S6,S7 also have exynos cpu and they all have LineageOS.
I read a post in S5 forum. The first dev make CM 12.1 for S5 said that exynos in S5 is the most terrible. But it have LiOS now.
I think our dev is move to another phone is the reason.

@But_Hacker: It's an established fact developers moved off Exynos on the S4 years ago due to lack of source code as well as documentation. What you're seeing now is not related but is simply because the S4 turns 4 in April, 2017.

Man, s2 and s3 is older than our device and they have CM or L os in android 7.
I think i will have android 7, soon. In this year.

I don't ever recall saying it was impossible, just very difficult. The simple fact of the matter is you have to have developers to do this stuff, and a lot of them refuse to work with Exynos for the reasons noted above.
I personally don't have this problem as my roomie's SIII and my S4 both use Qualcomm processors. Just lucky I guess.

Well i see you post below. You means S4 exynos dev is difficulit because of source code and document.
But S5, S6, S7 now have many document ? that is why they have CM or LineageOS for them now ?

On Exynos or Qualcomm? I don't haunt every Samsung forum, especially as my current device is a Nexus, so what those devices have or don't have isn't something I pay much attention to. I do know however that the documentation, while still incomplete, had improved for the S5 - S7.
I do believe the JDC Team may be able to attempt LineageOS on the I9500. But you'll need to talk to them and get them an I9500 for development.

Custom ROMs Request

There are only few custom roms released for exynos version till now.
I request the devs to please release some roms for the exynos version as well.
I saw many roms for the snapdragon one , but very few are there for the exynos one.
Looking forward to the devs :laugh: :good:

It's all about the Exynos source, as to what get's released by Samsung and what doesn't. The Devs cannot do a lot without up to date sources, and Samsung are not very known for distributing them. They either release part sources, or really outdated ones.

Ohk , thanks for the reply.
Then we can't do anything except waiting for Samsung to release the sources

G928 Source codes released

Hy all,
I love this phone, but one thnig disapoint me : NO roms oO NO customs roms at all !
I have nexus devices before, and all this custom think missing me ,
I read than developers don't love this phone because SAmsung don't released the source code
but I see this on Samsung website :
http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=sm-g928
It's all versions source
It's not enought to start real developpement ?
Source code is not the issue. A locked bootloader is the issue, on Verizon and AT&T anyway.

Cm or aosp no, but you have a lot of roms and kernels in the development section.
the problem is that exynos is not open source, especially some hardware blobs!
that's the reason why qualcomm based devices will get cm and aosp, exynos based devices would need a lot of fiddling and reverse engineering, thus cm/aosp support is often not the case!

Any developer Alive? Why there is no Custom roms for Samsung A7 2016 (SM-A710F)??

Is there any custom Roms for Samsung A7 2016 (SM-A710F). I have tried search custom rooms for my device but no luck?
I request to Room developers to please port some custom roms for this device i will be highly thank full to you guys. i am sick of using Samsung stock rom :crying::crying::crying:
Please do not ignore this post......
Me too, please create CM 13 for a710fd
Yes, please!
Anything but the boring Samwiz.
Let's keep this thread alive, so it may have some visibility.
i don't know why no developer make any ROM for this fantastic device yet. i have been using this device from the day it release and i am still in love with it........ Developers please do some thing i really need a change of ROM for my love(device)........
Agree absolutely! I have a lot of issues after uprading to Kitkat and then Mashmallow, with each upgrade introduced more serious issues rendering the dual SIM always on a useless feature. Really tired of Samsung ROM.
By custom roms, I assume you mean AOSP roms... Well, our samsung A7 & A5 2016 has exynos soc (except the A7100 & A5100, both has snapdragon I think). Exynos is somehow closed-source which means AOSP roms created for exynos devices are full of bugs because of missing source for the CPU. That is why less/no developers build AOSP roms for exynos devices.
In short,
exynos = closed source
closed source = no developer interest
no developer interest = no custom roms
sad
Rom Found
Finally i find a rom for A7 users :good::laugh::silly::victory::highfive:
https://forum.xda-developers.com/samsung-a-series/development/advanced-seven-t3509237
Need more Roms. Specially lineage based Roms for this device
There are a few...
I am using Centaurus ron as my daily driver and its free of bugs.
The developers upfate it regularly you can chec it out here https://forum.xda-developers.com/samsung-a-series/development/rom-centaurus-v1-t3833685
We have a git of bunnyy to compile, we have everything to make a Lineage 16

Question: who here would like an official lineageOS Nougat build?

Question: who here would like an official lineageOS Nougat build for all variants of the Samsung Galaxy Note 4?
Just want to see if its worth the devs time if there are any devs out there that will maintain this device.
+1
Reporting Via N910G.
There are already several Nougats builds for F/G/V variants in the Devs threads mate and many users are using/testing them. I'm not sure that you will get any "No" in your poll

But are they official? and what about other variants? What I'm asking is an official all-in-one universal that supports all of the variants.
Im sure theres more then 4 people and myself who would like an official build. Kinda sounds like your comments just make this poll bad and thats why only 4 people and myself voted. Your post makes it sound they they are official when not.
My note 4 is only 7 months old and was Manufactured August 2015 so this device is not really 2 years old and As Samsung was making them still in half way through 2015. Am i the only one who loves this device more then any newest samsung devices? I mean it beats the note 1,2.3,5,6,7 and also s models.
A unified build is planned: [DEV][trlte] Unified LineageOS device tree for Snapdragon Note4.
In the meantime, see my signature for daily builds of 4 trlte variants, which correspond to 7 model variants.

Samsung Galaxy S6 & S6 Edge Exynos Kernel Source Code Is Out!

Hello guys just want some info.
I'm not an expert at software and customizations, but i want to ask you guys some more info about the source codes of Nougat for our Gs6/Gs6e.
So the source codes are released is it now possible to create custom roms like Reserrection Remix, LineAgeOs etc?
Or are those sources only for stock samsung roms? Because it wasnt possible to make custom roms ''AOSP ROMs" when the phones were released, and now samsung released the sources codes so its is possible again like the galaxy s5 to make awesome roms?
Zip file is 170mb.
Here is the link to the Nougat kernel sources codes: http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=G920f Slow Download Speeds
SM-G920F - G920FXXU5EQAC Mega Download Link: SM-G920F_NN_Opensource.zip Fast Download Speeds
Let's hope we get badass roms
This is kernel source code, for good AOSP we need Exynos source code.
What can this kernel? or what they do?

The kernel source provided by Samsung is used for every custom kernel compatible with exynos 7420. With the Nougat version of the OS pack, developers can now build full-compatible Nougat kernels for S6 & S6 edge

ooh ok thank you
925T compatible?
This mean good pictures quality? Good camera? Or the kernel is different than the drivers?
No xD
The kernel is the road between the OS and the hardware, it will translate every informations sent by drivers (example: camera.open) to the dest. hardware.
Famous Exynos sources aren't there, that's only the kernel.
Samsung could release Exynos sources like Broadcom did, just we need a big amount of people and a petition.
