[Q] Is the F model different than the A (att) model? - Samsung Galaxy Alpha

Hi!
I am looking to buy this beautiful device.
There's a good deal on the ATT Version (G850A) UNLOCKED.
The question I have: is this the same as the F version (international unlocked)?
I want a device that can support LTE bands in my home country (1800), and does not have carrier bloat or depends on carrier updates. So my question is - can I buy the A and flash it to make it like the F?
Sorry, totally noob in this.
THANKS!

SM-G850F is with Exynos 5 Octa 5430, and SM-G850A for AT&T is Snapdragon 801

850f is octacore 850a quad core.
850a has a ton of lag. And battery drain.
If u want the octacore version with LTE
The 850m is the north american octacore version

Thanks so much! never even knew there was a G850M. Maybe they are rare?

is there a regional lock on the ATT variant? Also - is it possible to ROOT and put a different ROM on the ATT variant? Thanks?

no at the moment

Who locked it? ATT? Why would they do that?

Get the international version i9100 or i9100P (has NFC)
Sorry do you have 4G network in Jordan?
@Nyssa1104 thank you man for reply international version has 1.2GHZ but t-mobile has 1.5GHZ why international are better i dont know if we have 4g but i certain that we have 3g
Definitely get the international version if you're planning on using custom firmware.
There seems to be a lot more development that has happened/is continuing to happen for this variant as opposed to the others. But as Nyssa mentioned, if you can get one (international) with NFC (so you can use it as a virtual wallet/tap to pay, etc) why not
@MistahBungle thanks man i didnt understand you so i will rewrite the question in another type if i bought a T-mobile can i unlock it to apply our Sim (orange,zain,ect) and what is the different between international and T-mobile
I honestly don't know if the T-Mobile version will work in your country or not (I have international version). The T-Mobile has slightly bigger screen, different processor, 4 touch buttons, support for 42mbps data speeds, and supports 1700mhz UTMS...This is all as far as I know. You might want to do a bit more research about the features yourself.
You might want to ask your carrier if this phone will work on their network or not before buying it.
thanks guy for help but i have a little question to people who used the 1.5 and 1.2 processor is there a big different between them
Are you sure you don't want a Galaxy Note? I wouldn't buy SGS2 now, when GN is out.
But if you get one, get the international.
AFAIK it's the same processor, only OCed a bit, what you can do with a custom kernel aswell.
T mobile sgs2 uses a qualcomm snapdragon which is based on the cortex A8 vs the A9 in the exynos and as such is slower clock for clock, so the 1.2ghz exynos is faster and has a better CPU.
I would go for the i9100, it supports GSM (2g) 850/900/1800/1900 and 3G 850/900/1900/2100 so make sure it will work on your network.

PS, I was bored so I checked the networks in Jordan, and as far as I can tell, they use 900 and 1800 so at least it will work on edge/2g and should work on 3g (old thread where someone said they are using a at&t iPhone 3g there on 3g fine, and the i9100 covers the same 3g bands) but I can't find any hard info so I can't be 100% sure.

I recommend buying the International i9100 BUT make sure it isn't the i9100G. It's far worse than the original i9100. Aside from that the AT&T SGS2 looks good too

No, there isn't. Nothing you're gonna feel in day-to-day usage.

SIII only Dual Core??

So... Galaxy SIII in Europe comes with quad core processor - or so I've read... Why does the US only get dual core?? Can I use a European SIII on US T-Mobile network if I can get one?

The US version has qualcomm chip which supports LTE, the Exynos does not... INTL version has 1GB RAM, and qualcomm has 2GB RAM, yes you can use an unlocked INTL I9300 on T-Mobile but will not get LTE and have less RAM... The trade-offs are up to you...

Because the Exynos processor doesn't work with T-Mobile's non-standard 42Mbps on AWS (1700 MHz) and it also doesn't work with the LTE. You can use the international one on T-Mobile but you'll only get EDGE data. If you use it on AT&T though you'll get up to HSPA+ because most of Europe uses the same bands as AT&T (850/1900 MHz). If you want to use international phones, T-Mobile is the worst carrier to be on in terms of data speeds, but they're moving to the same frequency as AT&T, so eventually you'll be able to use it on T-Mobile with up to 21 Mbps.

To be fair, the i9300 is a lot faster than the US models. But to be honest, unless you game, you won't notice a different. The 2GB of RAM was a "whoops, my bad" from Samsung for having to switch processors; RAM does not affect performance unless you have too little RAM. Even the Nexus 7 comes with 1GB of RAM. But anyways, it depends how you use your phone. The other big thing is that the US models have the "bug" or "feature" where you might lose your IMEI when flashing anything to the phone, with no chance (so far) to get it back, meaning you'd have to do a warranty swap to get a working phone. The i9300 also gets major updates first. Development, I would say, is about the same for both though.

I'll try to reply in a nice way before you get flamed by someone. The quad core version (International) does not support LTE, hence we have the dual core setup which does support LTE. You can use an international device on ATT and T Mobile minus LTE. If I recall correctly you may not even get HSPA + either but I don't know if that is true or not.

Damn you beat me to it.
Damn we be on this one... LOL
Slight correction. There is a quad-core Exynos that supports LTE. Korea got it, but it wasn't completed by the time the US variants were in full production.

Because the LTE radio is separate from the Exynos SoC. The Exynos itself does not support LTE. Think HTC Thunderbolt. What this results in is horrible battery life. The Galaxy Tab 7.7 did the same thing with the Exynos dual-core, adding a separate LTE radio with the Exynos processor. If you need LTE, you're better off with the Snapdragon S4 (which is no slouch btw). We're at a cell phone generation where all CPU's perform pretty much the same (current gen meaning S4 - Tegra 3 - Exynos Quad) until you really push them. So again, unless you're benchmarking or heavily gaming, you won't notice a difference.
Also, yes you'll get HSPA+ on AT&T (I'm using my i9300 on Straight Talk), but only EDGE on T-Mobile.

I'm starting to think even Samsung doesn't have a clue what's really going on with that... or a very ingenius way to sell some phones at full price... Hasn't deterred me any...

Samsung supports developers. They gave the entire CyanogenMod team Galaxy S II's when they first came out. They hired Steve Kondik (Cyanogen), and they worked with XDA devs to try and fix the ICS recovery perma-brick issue on the SII, Note, and other phones. It's probably the carriers that messed with the software without knowing what they were doing.
if you haven't heard already from previous posts the USA s3 supports lte and the UK one doesn't and we also have 2gb of ram they do not but they have a quad core chip to even it out and to be fair.

4G Antenna

All S3 has the 4G antenna, they just pick up different data freq? I got the i9300 and currently reside in US under AT&T. KNow if there are anny ways to receive 4G? The phone according to specs can only do 4G in europe and such, but any one have any idea?

i9300 does not have LTE. The max you get with it is hspa+
Unwanted info: As of today you will get edge only on T Mo US.

where did you find that spec??? It's wrong.. international version doesn't have a LTE/4G Antenna.
Only the Korean (exynos) and the US (qualcomm s4) versions have 4G/LTE as far as I know.
Most of the websites say the s3 is 4G friendly or regional, etc., All that means is it's supported in certain regions (south Korea, US)
The i9300 does have the 4g bands except 4g lte bands for AT&T in the US.

We don't have 4G LTE bands, but we do have "faux" G bands though.

International LTE vs US LTE

What is the difference?
are the bands different from one to another, will the international LTE not work with the US LTE? im just saying for instance the Note 2 has LTE built in with the exynos quad, what will be different with the US version if it will have the same quad with LTE as well. Why wait for the american varients anymore?
any ideas, i have looked at some things.....and cant really make to much of it. except that verizon and at&t both use the 700mhz band for LTE
just wondering if someone with a little more knowledge of the network can tell me if the Internaltional version will get LTE here in the states....if so why would they release a US veriant

i know that for some reason the quad core processors dont play nice with our US LTE for some reason right now thats why all the exynos we get are only the dual core supposedly this will be fixed soon

Is it possible to install stock S21 ROM on S21 AT&T (USA) version?

I am thinking of getting an S21 from AT&T because of the deal they have right now, but I don't like AT&T bloatware. I'm a noob when it comes to phone firmware and such, so I'm not sure what is or isn't possible.
My understanding is as follows:
Carrier unlock is possible via AT&T website to use other carrier SIM cards.
Bootloader unlock is not possible on AT&T devices (starting at V2 seemingly?).
I'm just not clear if you need an unlocked bootloader to flash the stock S21 ROM on an AT&T device. If not needed, what is the point of unlocking the bootloader, just for root?
Any clarity is appreciated.
You can use "patched ODIN" to do flash "U1" firmware, which removes bloatware.
Not sure about the bootloader, I think you're correct on that.
I flashed an Xfinity Mobile S21 (carrier unlocked by them) to U1 but so far the phone is refusing to use the proper carrier settings for VoWIFI (I have a VZW sim in it now). It worked for 1-2 weeks previously. Everything else seems to work properly including VoLTE.
I'll probably switch back to Xfnity Mobile to get VoWIFI working again.
Thanks for the response.
can I ask something related? I got my Samsung S21 from Amazon unlocked and I'm in International market. the phone has esim capability but it's locked up. my question is (can) I flash international firmware or let's say the one being sold in the middle east? I'm stuck with single sim which is pretty annoying. what do you guys recommend

My understanding is that the international firmware is not compatible with the US phones because the US version uses the Qualcomm Snapdragon processor, whereas the international phones use the Exynos chip. I think you're stick with single SIM, unfortunately.

the snapdragon version is only sold in the US solely?
"International and Korea models of the S21 utilize the Exynos system-on-chip, while the U.S., Canadian, Chinese, Taiwanese, Hong Kong and Japanese models utilize the Qualcomm Snapdragon 888."
