Custom ROMs for (International-) Exynos Edition - Samsung Galaxy S7 Edge Questions and Answers

Some months ago i had the S6 and i was just disappointed about the poor custom ROM devellopement. I guess it was because the Exynos sources were far more difficult to get but i remember back in the S3 days we were even able to undervolt. So do you guess this time there will be better support.

No, if you want aosp support snapdragon all the way

Note 5 under exynos has mutliple ROMs and Kernels. Check the section. Maybe some devs will come here and take care of the S7Edge.

@0xE2: But there are a lot of TW-Based ROMs and several of them are very good. AOSP ROMs aren't the only ones out there. The ROMs we have for the Note 5 have all of Samsung's features and the awesome devs have corrected most, if not all of their issues.

[Q] Note 3 drivers & CyanoGenMod

Dear Note3 users,
I am wondering about buying the Note 3 - however, I am afraid it will turn out the same as with my Note 1 - lack of proper drivers for newer AOSP/CyanoGenMod and the resulting problems (especially - phone reboting when taking pictures and occasional UI stuttering etc.). I remember devs blaming Samsung for not releasing the source-code for the Exynos-based devices back then..
I suppose the current CM KitKat builds are fine with N3 - what about future builds, especially when moving beyond KitKat? Has Samsung done a better job at supporting the N3 and AOSP/CM thus far (when compared to the N1)?
Thanks for all your replies..

I can't answer your question directly - I don't use CM/AOSP - but I'm interested in the way you asked your question.
I don't see that Samsung have any onus or responsibility all to "support" CM and/or AOSP. As I understand it, they release the source codes for all drivers that they are legally obliged to and no more.
I'm sure the rest is a PITA for CM/AOSP devs, but is that unique to Samsung? Don't Sony, HTC etc do the same?
Personally the only thing I like about CM is the theme choices, and now there are Xposed modules to port many themes to TW based ROMs. If I wanted CM/AOSP, I'd buy a Nexus.
I've nothing against TW framework, it's never let me down, and I've had the SGS/2/3 and Note 2 previously. I don't use the TW launcher, stock icons or stock kernels. I have tried a fair few CM ROMs over the years, and never had a single one that was 100% bug free.
Put it this way - I like stability in my phone, and by definition any ROM that needs nightly builds isn't going to supply that "need".
My 2 cents. Whatever floats your boat is fine, that's why we don't use iphones

[Q] Is there any Dev's going to do work for the G900H version of this phone?

Id like to find out if there are any custom roms for the G900H or if there is anyone that has one that will be customizing the stock rom etc... Kinda sad that there is no one yet Is it because of the CPU???

I am also interested in knowing the answer to this question.. infact the s4 exynos has got the custom roms so will this device follow suit?
Dunno.
Seems people are even less interested this time.
S4 had AndreiLux for custom kernels.

I dont believe that the reason is people not interested. I think its matter of time. First,this is the newest version, and also, the most difficult built with 8 different cores.

Number of cores are completely irrelevant to the difficulty of building a kernel for Exynos. It's all about knowing the platform, the capabilities and what you can and cannot do. Which comes with experience...
It's just a matter that Samsung drove away all developers from Exynos. We used to have really talented devs on this side (Entropy512, Codeworkx, among others), but the lack of support from Samsung and lack of sources for Exynos burned them out.
S4 had AndreiLux, who is an excellent dev with tons of knowledge.
N3 has halaszk, which has done a great job and also brought back features from S4's perseus to the N3.
Don't really expect much for this device. It's not a matter of time, N900 (Note 3 Exynos) doesn't has an AOSP rom and it has been several months now.
I will likely build something when I get time, I frankly want to improve a couple of small things and increase GPU clocks to offset for the lower performance compared to the Adreno 330... but it will take a while, thanks to halaszk's work, I know where to poke.

Will you only build a kernel or a complete rom?? I just so want stock looking custom rom hahahah

[Q] Request : Note 3 N900 ROM with S6 features and apps

I've seen a couple of ROMs like these for the Snapdragon powered Note 3 with a lot of S6 apps ported to their ROM. Is any such ROM in development for our Exynos Powered Note 3? For now I'm running Stock Lollipop with some S6 apps like Music, Smart Manager, TW Launcher etc, but It'd be great to have a completely new ROM built with S6 features and such. The phone app looks a lot better and resembles Vanilla android. If anyone is willing to try, I'll help you with the testing part.
Thank you
We got so less developers for note 3 n900 :/
We can't get s6 roms so much early maybe we have to wait for another 5-6 months

So true. but would we ever see a S6 ROM port soon? Even though we have a few devs, they've done some great work like giving us CM12 and such. Hopefully we'll see this too
Need it man....

AOSP or Google-based ROM?

Are there any AOSP or stock Google Android ROMs out there for the S8? I'm not keeping my hopes up because I owned the S7 Edge ever since it came out and it never really came through. The reason I am asking is because I just found out there's a MultiROM tool for the S8 and I'd like to take advantage of that. If there aren't any AOSP ROMs, what are the lighest, most de-bloated TouchWiz based ROMs out there that feel like stock? I'm currently on BatMan ROM and it will be my primary ROM and I am looking for a light second.
Thanks!
There are no aosp roms yet.
Why is it that it takes so long for AOSP ROM's or Lineage based ROMs to come out for exynos devices? I'm just curious because Samsung released the kernel source for the exynos variants. I might be just asking a noob question but I'm curious what's involved in making a AOSP ROM for these devices.

Kernel development, porting, baking, bug fixes before release. There are a lot of steps involved that need someone decently motivated to take.

I'm willing to bet a few developers might be messing around with Lineage/AOSP. You have to consider the fact that there has never been an Exynos device running AOSP straight from Samsung. They have to build Android from the ground up for Exynos devices instead of just rooting and adding tweaks.
AOSP based roms for SnapDrgaon phones are a dime a dozen. Developers can look into other phones for bug fixes and common issues. With exynos, the developers have to fix bugs with no preexisting knowledge base to draw from. Besides what they know from Touchwiz Android builds.
Give it some time. The longer the phone has been out for the more hands it gets into. Especially when discounts are put out.

Custom/AOSP Roms/Kernels?

So I got an S8 the other day as an gift. (G950F) Looking around there seem to be a lack of custom AOSP kernels/roms. Mostly everything seems stock-based.
Coming from previous phones this usually means one of two things. Lack of devs or something hindering development. I.e locked bootloaders.
I know the S8 had issues with Odin due to the new bootloader. Is this still an issue? Is there anything I should know before going neck deep into kernel-sources?
Well, that's because of its processor and platform, usually Snapdragon devices tend to have a lot of development because Qualcomm based platforms are way easier to work with because of it's common source code and architecture, exynos chips seems to be a little bit more messy, they are exclusive of Samsung devices and I think they have a complete integration with Knox and all of that stuff, besides of its architecture and configuration, maybe in the future it will have some AOSP rom, the Galaxy S6 got his first official lineageOS build 2,5 years after its release and it didn't work that good compared to stock, so who knows, you should check the different roms they have around, I'm using RenovateICE on my S8, running alright with some tweaks, you should take a look to S8/S8+ cross device development, there's all you need!
Greetings!
