ROM advice please! - Samsung Galaxy S7 Edge Questions and Answers

Looking for advice. I'm Verizon SM-G935U (V) Snapdragon 820. I've used some ROMs but I tend to get these brief pauses or hangs using apps. I noticed my GF doesn't get them with her stock S6. Is that just a custom ROM issue? What I'm looking for is the most barebones ROM with best battery usage out there. I might use 10-15 playstore apps. And stable so there is none of those brief hangs. Or would stock ROM suite me better?
I was all set, after reading about a bunch of them, to try Superman. Then I found out that doesn't support Snapdragon variants. Is there any ranked up there and similar with Superman that will work with Snapdragon processor?

None of the roms in the Exynos S7 Edge forum are compatible with phones that have a Snapdragon CPU.
Sorry about that...
Have a great day.

I guess I'm understanding that not much is done for the snapdragon version? And if it is, it's for the SM-9350?

[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] Snapdragon or Exynos?

Hey,
I am sure this has been discussed many times here but i just want to know if i have a choice to buy either of these versions which one should i go for if i want to install custom roms? I mean devs release more custom rom's for the exynos version correct?
Thanks
There has always tended to be more developers releasing customs roms for the snapdragon version. The general consensus that if one wants to use customs roms and kernels etc then the best choice would be to go for the snapdragon version. Again there are developers who release exynos custom roms and kernels so don't think it will be the end to modding you note 4 if you go for the exynos version.
I am in the same situation and had a snapdragon note 4 but just felt it was laggy maybe i am finding this more of a problem due to being a iPhone user for years. I won't go to why i have not taken to the iPhone 6/plus lol.
The exynos version has been winning benchmarks over the snapdragon but what made me ultimately go for the exynos version was that it beat the iPhone 6 plus in a head to head that is incredible in my books. Choice is yours......

[Q] Can I use the 910C (Exynos) in Hungary?

tl;dr: ^ See topic text. ( I guess I would not have LTE here with that, but that's not a big issue at all. Coverage is horrible in Hungary anyway. )
A few shops* sell the 910C here as well, not just the F version.
Now I know that the Exynos version is faster, more power efficient.
And I guess all official updates will also reach this variant faster or pretty much with the same speed.
On the other hand, we have the Snapdragon, which got much more custom roms and section on XDA.
(Honestly it feels so weird that the 1.9ghz A57 can beat the S805 clocked at 2.7ghz in single-thread....)
Anyway. Personally, I used the S3, S4, Note 2, S4 Mini, Motorola phones... and every time I installed Cyanogenmod or other CM/AOSP-variant roms, it was riddled with bugs.
Don't get me wrong, the Note 2 have the DN4 Rom which is basically a Note 4 rom ported, and it's great. It's stable, it's got a few quirks, but it works.
But from that, it doesn't seem to be a good deal to trade speed, and power just for more roms. (Let alone Knox which I don't want to trip.)
Sooo... I would be pretty fine with the Exynos version.
But can I use it here?
* = all gsm shops are shady in the country, that's why I'm super-cautious.
Use Exynos in Hungary
If you mean just using it as a normal phone I don't see why not.
The type of processor will have no influence on the normal use of the phone. (as in calling, texting internet and email and such)
If you would want to root it and start working with custom ROMs it might not e the best idea. Most open source development is on the Snapdragon variant.
The AOSP ROMs have come a long way over the last couple of years. I experience hardly any bugs with the bigger devellopment teams.
All the best, Willem
Thank you! Well, I know the difference is tiny, but you cannot install roms and stuff without tripping KNOX anyway. It will be a business phone so I would like to keep my warranty.
Not sure if allowed, but please, excuse my bump.
I would like to order the phone as soon as possible.
So far I'm convinced that the Exynos will be fine for me.
But the main question remains. Can I use it in this country?
I tried to look up the chipset, the phone, everything - but there is just no information on what frequencies does it support / etc.
So I had a wild idea. Screenshot the box at unboxing on Youtube, so I can check.
Then I used this:

That says it should work. What do you guys think?

Which model is recommended for custom roms?

I'm in love with the hardware of the galaxy s8 so I decided I want to buy it (Although I hate Samsung Touchwiz)...
but I'm torn of which variant should I buy - the unlocked US version (with Snapdragon 835) or the international version (with Exynos 8895).
honestly I prefer the snapdragon chip for the popularity of snapdragon but I heard the unlocked US version rarely gets updates .
Another major consideration is that because I hate Samsung Touchwiz I hope (someday) a custom AOSP rom will be released for the phone (like Lineage OS), so I want a model that will get custom rom support fast...
so my question is-
Based on the above, Which model should I buy?
Furthermore, Which model probably will get root and support for custom roms first?
Thanks in advance
You will never see a working aosp rom on a samsung phone..if you hate tw.. I suggest you to run away from this phone and never look back
Well looking at S7 Edge, for some reason Snapdragon, which is usually considered as more opensourced etc than exynos, didn't receive any custom ROMS, especially AOSP. Surprisingly, Exynos did - both Lineage and ResurrectionRemix are available, however, it took time to release them, I guess it will also take some time for S8 to receive it's 'clean' Android ROMs. Not sure whether Snapdragon variant has locked bootloader, but if it is, then it may be a hard nut to crack

If you really want custom roms then maybe you shouldn't go for samsung. First is development on exynos is a pain in the a*s for devs, second as mentioned it takes some time to develop a decent AOSP rom. But if you really want a samsung device then yeah, go for Exynos international, Qualcomm is locked and hard to tinker with.

Whick SM-950 should I buy?

I would like to buy a S8, but I really love to have it rooted and use some modifications and custom roms, so which model of S8 should I pick?

Then g850f or g850fd. Those two devices are just compatible. But you should remember that a root detecting hardware (called knox) will be triggered and you will never be able to use samsung pay unless you changed the motherboard. But you can still use android pay (so far) by using systemless rooting.

Is there anything else that would be unabled after rooting? Would that affect the camera too? I don't really use that much the Samsung pay thing so that won't matter to me.

With Magisk root you will be safe until Google tries to block root again (its been a few months since the last time). Keep in mind though the G950f is the exynos version so you will have custom roms available but they wont be functional. There is an unlockable Snapdragon version (G9500) but nobody is making roms fort them YET, but if they do they will be full functional. Go for the Exynos version though, its the only thing with support currently.

Why won't the custom roms be functional? Which has better performance, exynos or spandragon?

The information given to you is incorrect. Magisk root, the root is always there, the only thing that gets updated that might effect you is safety net, some apps like Snapchat and Pokemon go need the device to pass safety net checks, magisk has a built in function to make the checks pass, Google can periodically update safety net checks and in turn a new version of magisk is released to make sure this new version can be pass the safety net checks.
As advised previously doing any of the above will trip Knox, everything is custom roms work except Samsung pay, everything else works great.
Imho the exynos version is better.

Custom Roms for the exynos will never have a functioning camera, go to the cross development sub forum on here and scroll through some of them too see the full list of things that do not work on them. As for performance that's debatable, the snapdragon can use Google's hdr+ canera app and get pixel quality photos but exynos is better for pretty much everything else until development for the snapdragon starts. The exynos version is cheaper and already supported for some tweaks, that's why I chose it over the snapdragon.

What are you on about, custom roms using Samsung stock s8/s8+ firmware as base are have fully working camera, it's only the note8 ports where some of the functions don t work
So the best idea would be buying the 950F and use custom roms that uses stock firmware?

That would be the best bet, there are quite a few roms based off of s8 firmware you can try out

I'm not trying to argue but modified stock roms are not custom roms they're just the lazy mans roms with a few swapped out apps. AOSP will not be getting a functioning camera, nfc, sms, calls, torch, fingerprint reader, or bluetooth audio anytime soon. Exynos never does, and region specific snapdragon variants have killed custom roms since the S6. You can get the same setup of modified stock roms on either the snapdragon or exynos, the price difference is the big deciding factor though.

You clearly don't know what's involved in cooking a custom rom up from stockbase and what the devs do to enhance and bring new features that the original firmware didn't have, making changes to framework, updating libs and so on, the definition of custom matches what I've said. So your pretty much calling every dev who's made a non aosp Rom lazy and that's disrespectful.
That's the last I'm gonna say, I've given the op what he needed to know.
