Do you mean G955U? G950U is the S8 and G955U is the S8+
Sent from my wickedly kewl Galaxy S8 using my fingers. Duh!!!

Do we know for sure this particular model (US Variant) is locked? A lot of hype built around the fact they went that route the first time...

Yes, we do. Lots of people in the TWRP thread wondering why they can't unlock their phones too.
Basically you bought the wrong S8 if you care about easy dev stuff. Unlocking bootloader, rooting, ROMs, kernels, etc.
Now Verizon and Sprint users don't have a choice. Qualcomm has patents on CDMA modem technology and the Exynos variants don't have CDMA. BUT other carriers like AT&T or T-Mobile, Exynos would be better.
Or for Canadian users too. They got Exynos variant with bootloader unlock last year but this year got Snapdragon.
EXYNOS VARIANTS LTE BANDS:
LTE Bands: FDD: B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B12(700), B13(700), B17(700), B18(800), B19(800), B20(800), B25(1900), B26(800), B28(700), B32(1500), B66(AWS- 3) | TDD: B38(2600), B39(1900), B40(2300), B41(2500)
GSM/GPRS
850 / 900 / 1800 / 1900 MHz
3G/HSPA
850 / 900 / 1900 / 2100 MHz
You order off ebay, BUT make sure you choose a dealer who will disable the regional lock like Clove in UK does. Google Clove UK.

This time around SN 835 seems equal if not better than the exynos in terms of battery and speed. To bad we dont get root or.unlock bootloader

[Q] GTi9505 = AT&T i337?

Hi, so I understand the differences between the 9500 vs the 9505.
I'm buying another s4 off of contract, so I am looking for the best spec since I am paying full price for the phone.
If I am going to use the phone on the AT&T network (need a phone that utilizes AT&T LTE), (also spend time in Korea so international use would be nice), are these unlocked carrier-free 9505s any different than the AT&T i337?
Is the unlocked version (9505) run more bands than the i337?
TIA.
Just found my answer on Wiki, seems the LTE bands are different.
9505:
800, 850, GSM, 1800 MHz, IMT, IMT-E
vs
i337:
700 MHz (Band 17), AWS, IMT, IMT-E

The I9505 is also the only variant that has FM radio
So does this generally mean that the 9505 will not run on the AT&T LTE network? I'm also in the market for a full-price S4 ... that I'd like to use on AT&T while in the US but also have capability to swap SIM cards and use in Japan, South Korea, Spain and Norway. Thoughts?

the i9505 will work on 3G on AT&T, but not 4G. as for the other countries, look up their mobile frequencies and compare it to the i9505's. For example, here are AT&T's frequencies.

Guess I would have realized that if I had read the big (Verizon) text on that page.. Or looked at the photo of the back.
I assume the $200 trade-in doesn't apply to it, so for most it will be more expensive than getting a preorder.

correct lol and doubt we can get the $200 off on it. and i am going to go for it once my g3 sells and i get regular retail locked note 4
Perfect! Thanks!
I'm guessing this unit will work on most any US carrier. I back ordered mine on Samsung site, hopefully it happens soon and the price stays the same. There's chance may not even be charged tax and shipping is free.

Does anyone have any legitimate source for the LTE bands supported by the Developer Edition?
This is all that is listed on Samsung's site, and frankly, this tells me nothing.
2.5G (GSM/ GPRS/ EDGE) : 850 / 900 / 1800 / 1900 MHz;
3G (HSPA+ 42Mbps): 850 / 900 / 1900 / 2100 MHz;
4G (LTE Cat 4 150/50Mbps) or 4G (LTE Cat 6 300/50Mbps)***
Seems odd that they would omit exactly what LTE bands are supported by the phone.
-Thanks

Yeah, this is the unfortunately the same thing Verizon advertises about the Galaxy S5, despite the fact that it also at least supports 2600 (band 7) MHz(and likely more). Verizon only bothers to mention the bands in which Verizon supports, not the phone. Hence the request for a legitimate source. Thanks though.

Do you research it will have the same bands smh
digging into bands deeper the first thing you posted it has this at the bottom: * May differ by country and carrier
Network
2.5G (GSM/GPRS/EDGE) : 850/900/1800/1900 MHz
3G (HSPA+ 42Mbps): 850/900/1900/2100 MHz
4G (LTE Cat.4 150/50Mbps) or 4G (LTE Cat.6 300/50Mbps)
* May differ by country and carrier

Oh, I wonder why they bothered to display any specs at all, that last line covers everything. Syh all you want. Considering the Note 4 Developer Edition by all available information, seems to be a Verizon exclusive, it may be fair to conclude that "differing by country and carrier" might be limited to Verizon, and the USA. Further more, the Samsung site displays more/conflicting information with the Note 4 on Verizon's site. (non-developer edition). (4G (LTE Cat 4 150/50Mbps) : B2 / B4 / B5 / B12 / B17) -Hmmm, weird, more than 2 bands listed.
So to reiterate with clarity, does anyone have a comprehensive, reliable source to determine the LTE bands (and frequencies) supported by the Note 4 Developer Edition.
-Thanks

SM-N910F and AWS compatibility

I am looking to get a Snapdragon 805 based Note 4. The most common variant seems to be the SM-910F.
Is this variant compatible with WInd Mobile in Canada (AWS /UMTS Band 4 - aka 1700/2100MHz)? At the moment, Wind does not seem to have an LTE service, so that is not a concern right now.
Has anyone else attempted it?
A quick check on the US Amazon website and:
http://www.amazon.com/Samsung-SM-N910F-Factory-Unlocked-International/dp/B00NB1DVII
GSM (2G) GSM 850 MHz, GSM 900 MHz, DCS 1.800 MHz, PCS 1.900 MHz
UMTS (3G) B1 (2100), B2 (1900), B5 (850), B8 (900)
4G FDD LTE B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B17(700), B20(800)
The B4 (AWS) part makes me think that this should work on Wind Mobile.
910F is the international version with the Snapdragon 805. There is no 810 Snapdragon version of the Note 4. Since its the international version it should work fine.
Thanks - fixed typo.
But yeah I am thinking it will be fine as well.

I don't think it will work, the AWS band is being used for LTE. I would say get the sm-N910W
It is not.
Is there a database somewhere of model numbers of the Note 4 filtered by the compatibility with bands?
The 910T, 910F, and 910W8 seem to be compatible. Ideally I would like to have the Snapdragon 805 variants.
newbies
Just got the 910f thought it would works with wind but no such luck.
maybe I need a Modem flash of the ATT variant might be able to get it working but no luck finding that so far.
I will let u know if I can get it to work.

[Q] SM-N910W8 or SM-N910U ?

Dear Experts :
I'm in the process of buying a new unlocked Galaxy Note 4, after using my legendary Galaxy S II for 4 years so far, and i need your help regarding which version should i get ..
for those who are unaware the SM-N910W8 has the Snapdragon 805 CPU, while the SM-N910U has the Exynos 5433
i live in Canada and right now i am with Wind network, there is a slight chance i might switch to Fido depending on my data usage after i get my Note 4, anyhow my question is :
which of the two should i buy in terms of network speed, ROM development and availability for customization, Phone heating ... i honestly cant think of more differences than that but if there is then please enlighten me
Please help me decide .
up
I choose N910w8, for me is faster than N910U and more friendly with the battery... that's a simple opinion so good luck!
Wind or the Big 3
Wind frequency: UMTS band AWS (1700/2100) No LTE at the moment
Fido frequency: GSM, UMTS, HSPA and HSPA+ at 850 MHz and 1900 MHz. To access LTE network, the phone must be compatible with: 700 MHz on Band 17; 1700/2100 MHz on Band 4
First, let list some of the features of these devices N910W8 (Snapdragon), N910U and N910C (both Exynos 5433/Octa core)
For N910C Asia, Europe, South America version: Network 4G LTE FDD
2G GSM: GSM850, GSM900, DCS1800, PCS1900
3G UMTS: B1(2100), B2(1900), B5(850), B8(900)
4G FDD LTE: B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B17(700), B20(800)
***It cannot be use with WIND b/c it does not have band AWS for 3G but only for 4G. However, you can use this phone with the BIG 3 and on FIDO as it has 2 LTE bands, which FIDO currently using.
For N910U Hong Kong, Taiwan, Australia, New Zealand, Chile version: 4G LTE FDD
2G GSM: GSM850, GSM900, DCS1800, PCS1900
3G UMTS: B1(2100), B2(1900), B5(850), B8(900)
4G FDD LTE: B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B28(700)
*** it too cannot be use with WIND b/c it does not have band AWS for 3G but only for 4G. However, you can use this phone with the BIG 3 and on FIDO. BUT THE DIFFERENT BETWEEN THIS AND N910C is that this only has 1 LTE bands, which FIDO currently using and DO NOT HAVE band 17. So, you may not get good LTE speed compare to N910C model.
For N910W8 Canadian model: 2G GSM, 3G WCDMA, 4G LTE FDD
2G GSM: GSM850, GSM900, DCS1800, PCS1900
3G UMTS: B1(2100), B2(1900), B4(AWS), B5(850)
4G FDD LTE: B1(2100), B2(1900), B3(1800), B4(AWS), B5(850), B7(2600), B8(900), B12(700), B17(700)
*** It can be use with ALL CANADIAN NETWORK including WIND AND MOBILICITY. It can also run all LTE network in Canada at max potential b/c it has all of the bands, which Canadian Networks use.
If you choose to use WIND, your choice for which Note 4 model is clear
I have a friend who has SM-N910S model from Korea ( Exynos 5433/Octa core). He uses it on a Canadian network and he notices that his battery runs dry very quickly compare to my Note 4 (N910W8). I think that b/c for all of the international models like N910C or U, they have different radios and try to look for the signals differently compare to the Canadian version (N910W8). Hence, low life battery. So be careful and choose wisely as well b/c I do not think you want to have only 3-4 hours of screen on-time eh?
ROM development
Back when the phone was initially coming to the market, owning the Snapdragon was a plus b/c if I remember correctly, it was the 1st version to be Rooted successfully, while the Exynos have to wait. Same go with ROM as well. But I think the market has been saturated with both model, you cannot go wrong with either one. But I think that if you want to try out the earliest ROM or changes, the Snapdragon will be more suitable.
However, if Samsung decides to push 64 bit software support, then the Exynos variants are the best choice. But as of now, I think the Exynos still only runs 32 bit as Samsung has locked the 64 bit down. So will see!
Last week Sunday, I purchased my Note 4 from Wind on Wind tab $649.00 CAD. It is a great phone and I have no issue with it so far. The phone runs lighting fast, if you turn off some of Sammy features and animation.
I think present to you all of the information that I know about the Note 4 to the best of my abilities. I think you will be better off to get N910C rather then U if you have to choose between the two of them.
Now, depend on what you want and needs, N910C for raw power but limited as I listed reaons above or N910W8 for Wind and flexibility but lesser power compare to Exynos variants.
***TIPS*** if you look around expansys, ebay, you may get a good deal for N910C. But for N910W8, you have to buy it from Wind then. I would recommend you to buy out right as it a better option in the long run. If you have any question, let me know.
*****Source: from Samsung Website and GSMarena
Well, if you are a power user and need allot of processing power for apps and games. Then I would recommend the N910C rather than the N910U. As the N910C works on the same LTE bands for Canada while the N910U is design to work only on certain Asian specific LTE Bands. However you will still be able to use a N910C in Asia.

How can I order the Exynos bootloader & sim unlocked model in the usa?

Sorry if this is a dumb question. I've always bought my phones from my carrier (Tmobile USA) but I'm done with Samsung locked bootloaders. I want full root and development or I'll buy another brand that will allow those things.
Seems like trying to buy from Samsung doesn't offer me the option for the international unlocked version? Does that come later? Or do you buy from a third party retailer?
Like I said, sorry if this is a dumb question.... I've just always gotten my phones from the carrier or local shops... But nobody around here is going to have an international Exynos unlocked S8/s8+
Sent from my Rooted Galaxy S7 EDGE on Android 7.0 Nougat, here's the instructions how to do it!

Get it from clove.co.uk they ship to US. It has 2 year Samsung UK warranty (but you need to send it there for repairs).
You can also order off ebay, BUT make sure you choose a dealer who will disable the regional lock like Clove does.
