AT&T Snapdragon or Xynos - AT&T Samsung Galaxy S8 Questions & Answers

I currently own the AT&T Snapdragon and overall very happy with the phone.
Unfortunately, I always want the best and fastest.
Is the Xynos S8 that much better?
Do I lose anything by going Xynos in comparison to AT&T Snapdragon version.
I'm still within return policy so need to make a decision soon.
Thanks.

It is not much better/faster, you will likely not notice any speed difference in normal use. You would however notice the much slower mobile connectivity of the Xynos by not being able to connect to LTE.

And no band 30.

I was debating on the same thing. I decided to keep my AT&T for LTE and US warranty.

Why wouldn't it be able to connect to LTE? Just because it's missing one band?

U wouldldnt reap the benefits of band 30 which really isn't a big deal, I would just miss hdvoice for the time being until someone to figures out how to enable

So it will still have LTE on ATT? I'm debating between this or waiting for the Pixel 2. No LTE would be a dealbreaker.

Of course you'll still have LTE but not volte

Go Xynos if you want to root your phone

From performance stand point Snapdragon 835 is better overall than Exynos 8895. There is anandtech article about it.

If you want performance yea I'd say snapdragon is a little better but if you're looking for more customization go with Exynos do to the bootloader being unlocked

I'm excited for this phone. It's the perfect upgrade from my Dell Streak.
Wow I ordered one from the UK hours before this story lol. But since AT&T nerfed the processor, I'm not too bummed, and they don't have LTE in Seattle. Also, I have a Streak now too, and saw how AT&T dragged their feet on updates compared to the UK version, so I don't regret my decision
Still, good to hear this.
Can we just assume we'll also get HSPA+?

If this pans out, then yes. It has the same LTE/HSPA+ chipset as the Skyrocket.
Nothing new, just the same speculation as ever. Just a different source speculating this time.
I've been strongly opinionated in other threads, suggesting it's unlikely AT&T will release the Note, but I will gladly eat my words if they do release it. I've had little faith in the few other articles people've posted, but Engadget's a little more believable.
I'd love for an LTE version. I really, REALLY wish there were some way to implement LTE without switching from the exynos processor to the qualcrap. And it's criminal the way AT&T insists on removing hardware home buttons and replacing with the strip of 4 capacitive buttons! Why! That's a completely unnecessary downgrade!
If they release an LTE model and it's 1.5 GHz qualcomm with 4 capacitive buttons instead of the current physical home button model, I'll seriously have a hard time choosing between it and my current (awesome) international version. I'll have to give LTE a try to see if it's worth the sacrifices.
I wish the international version came with NFC so I can try out that android beam on ICS when it comes out
Man I couldn't imagine waiting on AT&T fail version until 2012. Glad I get to enjoy my non nerfed one right now. Grand theft auto 3 runs smooth as butter on this Exynos.

No Exynos, no thanks. I'll keep the international version.
there goes AT&T again screwing over a good phone...
just get a ****rocket it only has a smaller screen...
save your cash, get international version, get straight talk, save $70 a month, screw at&t

I dislike AT&T as much as the next guy, but what does everyone expect them to do? Their network is overcrowded. Getting some of their customers offloaded to their LTE bandwidth will only help. It's not their fault that Qualcomm currently has the only chipset capable of LTE. You can make a choice: slightly better processor performance and battery life, or faster download speeds. But regardless, AT&T releasing their new phones in LTE is best for everyone. Even those of us who don't have LTE phones could benefit if their 3G network gets a little relief as other customers move to LTE.

There's nothing wrong with the performance of the Qualcomm LTE-capable chipset. It works fine in my wife's Skyrocket. The only "issue" is that it doesn't benchmark as high as the Exynos for the fanboys who have never seen or used it in person. Maybe Samsung should get off its @zz and make an LTE-capable Exynos chipset to satisfy them.

I didn't mean to suggest that there was. I think the benefits of Exynos tends to be exagerated in these forums. That's why I said slightly better performance. In the reviews I've read (such as SGII vs. Skyrocket), I do get the impression that Exynos versions do have a slight edge in smoothness. Particularly when you consider that the Note has a faster chip than the SGII, while the LTE note will presumably have the same Snapdragon as the Skyrocket, but pushing more pixels. I think it's also fair to say the LTE phones do have higher battery consumption. So there are trade-offs. But the biggest difference is you can get a GSM version now, vs. probably getting an LTE version on some unknown date.
That settles it, I'm going to pull the trigger on the international version.
Anyone wanna buy the AT&T iPhone 4s that I'm going to buy and resell to offset the cost? (black or white, your choice!) ;-)

That comment wasn't directed at you. There were a few ridiculous posts above. And "smoothness" is all user perception. IMO, it's a bit of a crutch used to elevate one device over another when there's nothing else to criticize. I think the vast majority of people complaining about these things on the forums have never held/compared both devices in person - they're strictly going off Quadrant scores and repeating what others have said.
That said, I think the HSPA+/LTE Note will be out on AT&T in January - I don't think we'll be waiting that long for it.
I prefer the four capacitive buttons, but am bummed about the change in processor. I'd rather have the Exynos than LTE.

Different region Note 4..

I'm thinking of getting a Note 4 Exynos variant. I'm assuming it's coming from China and is this variant -
SM-N910U Exynos 5433.. Will this function in the UK as a regular snapdragon variant please?
And if anyone knows, can they confirm that the audio /speaker sound is actually superior with the Exynos?
Thanks

everything is superior with the exynos version. CPU is faster, graphics is faster, zero carrier crapware added, get full UMTS support. only thing is if you encrypt the first screen asks for teh password in chinese and prompts you twice (select checkbox and click OK). other than that its great.
Thanks but audio is the thing for me,, I'm hearing reports that the Exynos version dies does indeed beat the Snap one.. That's the icing on the cake for me if it's superior and not tinny /thin.
Not sure about Umts sir? What's that?
And if u encrypt? Not even sure how I'd do that? I'd just run it stock without rooting.
Would I get the firmware updates still ota?
Thanks
There is a thread on here with all the frequencies of each model. What you need to know is does the model you are ordering support all the frequencies that your carrier uses. If it doesn't support any then it's useless if it only supports one them you will have signal issues and battery drain
UMTS=4G data speed. yes you still get fw updates OTA. lollipop (next android) has encryption enabled by default with stock rom. you do get superior voice quality with exynos but its only 10-15% better not spectacular.

Heed help with buying snapdragon s7 edge.

Hi. Im living in Russia and there are only exynos variant available. After using rather bad exynos note 4 (overheat, bad reception, 3g/4g battery drain, poor aosp development) i decided to buy snapdragon variant of s7 edge. I believe samsung is using superior versions of their handsets in key markets such as NA and China. But for my surprise all s7 edge sold in USA are carrier bound. My question are there unlocked s7 edge snapdragon? What carrier should i choose? Will at-t and t-mobile phones work with other gsm carriers around the world. Also i need no carrier bloatware and unlocked bootloader. As for network i need band 20 800Mhz and band 7 2600Mhz.
Thanks in advance.

None of the U.S. devices cover band 7 nor 20 i guess, those bands aren't used over there.
https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe
https://en.wikipedia.org/wiki/List_of_LTE_networks
Also, normally carrier locked devices won't work for other carriers unless you hack (was not possible at recent devices afaik) it or pay for unlocking it. But you could be lucky there at the s7 with it locking just at first boot. It could be, that it'll lock to your carrier instead of the one you bought it from, but you'll have to verify that it works before, also it'll only work, if it never has been booted by any employ at the carrier you bought it to ship it locked already.

I saw people importing note 4 sm-910c to USA because its compatible with US lte frequences Same model sold in Russia. I think device itself can support this frequnces though they are not used there.
I'd wait before presuming the Snapdragon model will be superior to the Exynos, especially in terms of things like overheat and reception. It's certainly possible it will be the better option, but there is no guarantee yet. And especially with the debacle on the 810, Snapdragon haven't exactly covered themselves in glory recently.
Hardly anyone has the Exynos model yet, whilst there are a lot of T-Mobile customers in the US who have the Snapdragon, some of who are reporting being unable to use the VR headset for more than 30 minutes without the phone complaining of overheat. Wait until next week and there will be proper comparison reviews that go beyond Snapdragon having a few extra meaningless numbers on some benchmark. That's when an informed decision can be made as to whether it's worth going through the bother of buying your device out of territory and forsaking the manufacturer guarantee.

Good point. I bother buying snapdragon mostly because of lower TDP and better 4g reception in past models. If exynos become equal in this areas i see no point in importing. And i dont wanna wait long cause if i preorder before 18 march i will get free gear vr though i dont need it xD

Yes, that's why I've removed the post, mixed the numbering, sorry.
But if you take a look, at least here aren't any of those bands supported at the U.S. variants.

But what about carrier software? I heard some carriers replace stock samsung apps like browser. Also is it true what at-t and tmobile phones recieve updates later than their unlocked counterparts?

Would be the first time I hear something like the browser replaced by a carrier, but maybe possible, in common they just add stuff though and make small changes (modem, bootscreen,...). And yes, carrier devices in common get updates later, because the carriers have to incorporate their changes (which can be a few days to months, depends on the carrier), but at the european variants we're lucky with stock roms at least (or at least have been). In most cases you simply can flash a unbranded rom there through odin without second thought.

Ive lost track (another Exynos vs Snap question)

Im hoping someone can please help me get up to speed here.
A while back I was looking at whether to get the AT&T version or the unlocked Exynos version sold at Best Buy.
From what I recall, many favored the Exynos version as having better real life performance and meaningfully better battery life. Also no bloatware.
The downside was that here in the US it would not work for Samsung Pay. From what I remember it worked just as well on AT&T's LTE network.
I have tried searching the forums to figure out if all of this still holds? Has Samsung Pay been made available - either through Samsung or through some kind of rooting, etc? Has the network performance been confirmed as identical between the two?
I am trying to decide which to purchase so any and all feedback would be helpful.
Thanks.
SPAY will not work and data transfers will be faster will the ATT variant.
Despite this, you should get the exynos for its fast mutli core capabilites, assuming you have no hope for a bl unlock and you care nothing about roms.
No way in hell does the Exynos model work as well on AT&T as the AT&T specific model. Not even the 930U.
With the 930A, you're gaining...
3xCA (bonds 3 LTE Channels), 4x4 MIMO (not active yet, but will probably require 930A), 256QAM (33% faster LTE speeds), WiFi Calling/Texting, RCS Messaging, and VoLTE. If LTE is your concern then the 930A is the only way to go.

Thank you both for the feedback.
Really the only reason I was thinking about the Exynos was the better battery life...I dont care THAT much about ROMS, etc.

So just to verify - does this mean that the 930U will have WORSE data and calling performance on AT&T 4G LTE network?

Data performance maybe, but not calling performance unless you have wifi calling as a necessity. Most people have lived without it for years, so I don't know how big of a deal it is for most people.
Thanks. I dont use Wifi calling although data performance is kind of a big deal!
Other than slower data on the 930U are there any other drawbacks?
Are there any BENEFITS for 930U? Its just unlocked right?

Battery life difference between the Snapdragon and Exynos variants

When the phone was first released, there were many tests done which showed a HUGE battery life advantage for the Exynos variant. I'm curious if there has been any more recent testing, say, since Nougat was released, or with more recent updates.
I want to get a 128GB dual sim S7 Edge, but I'd need to switch carriers if I move to Exynos, for technical reasons I'll explain below. If there's a huge battery life difference, I'll do that, but if recent software updates have closed the gap, I'd rather go with Snapdragon.
(Technical reasons: It's possible to enable WCDMA Band 6 on the Snapdragon variant. I live in Japan, in an area where I need WCDMA Band 6 for my carrier to work. There's no way to enable it on the Exynos variant, but there is another carrier which uses Band 8, which would work, but the other carrier does not have quite as good of service terms.)
I've had the sd820 for almost a year and cracked my screen so I got a g935f recently, I don't think theres enough difference to justify one over the other, I would just get the one more convient for you to get, unless you like rooting than definitely get the international version
