Hello,
I'm a probably future owner of an i897 but I have some questions about the hardware and models variations
I like in Brazil and my 3G carrier use 2100 MHZ (Where I live) and 850 MHz on other states (3g on Roaming). I have an unlimited data plan, but with a max speed of 300 kbps (so far).
I'm looking for the best GSM android phone: Fast processor, huge screen (4" or bigger), big resolution (at least 800 x 480), TV output, Wi-Fi, Internet tethering, GPS. All roads lead to I9000 or i897.
At first I thought choose the i897, because it uses both 850 MHz and 2100 MHz, so I'll have 3g anywhere in Brazil. BUT and you can see my data plan have a speed limit of 300kbps, so I don't know if I'll use the full potential of 3G, at least for now. Eventually I'll upgrade my data plan to a 1 MBPS plan.
I can also get i9000 but it will work only in few states. Probably it work for one year (As I don't intend to travel too much in the next year), but after one year I can change my carrier and some carriers here only use 850 MHZ 3G. So choosing the i9000 I will narrow my future options.
What I trying to ask (or answer) is whether is better to have an i897 with full country 3G BUT with an extremely "locked" firmware of if I should get the i9000 with a better firmware option but with restricted 3G (3G with 70% coverage).
In order to answer that I have other 'sub-questions':
1) Does i897 have the FM radio hardware? Would a future firmware/ROM update enable it?
2) Does i897 GPS works (I recall AT&T Blocking GPS on blackberry phones)
3) I saw some comments (other phones) that some ROMs messed up with 3G band. The 3G frequency is a hardware or software configuration?
4) Some sellers are already selling, here in Brazil, unlocked i897 phones. Is possible to unlock the phone but a ROM update or I'll have to pay for unlock codes?
5) Which other features AT&T decided to lock (Removed from their ROM) on this phone?
6) Is there an I9000 variant with front facing camera?
5) One very important question: Aside from Droid x (which is not GSM) and HTC evo (which also if not a GSM phone) is the Samsung i897/i9000 the best android phone available?
I also thought about getting a Motorola XT720 but it is only US$ 50 cheaper and have a slower processor and no 850 MHZ 3G. Also thought about the HTC Desire (A8183 Australian model that have both 850 and 2100
MHZ 3G) but so far I find the i897 the best option (although I would love having front facing camera that the Desire have).
Any other options?
Thanks
Jose Morais
In answer to your question(s), the phone you want is the best one for you ...
1. No, the i897 is not supporting an FM radio at this time, and I'm not sure if the hardware is present as I refuse to open my phone to look. AT&T's specifications page does not list FM radio as a feature either, but that doesn't mean its not there and disabled.
2. Yes the GPS works, it is spotty for some and Samsung has admitted to there being an issue that will be resolved by an upcomming OTA update.
3. (For WM Phones): It's not so much the ROM as it is the Radio software, which may, or may not, be changed in the ROM. Different versions of the radio software can improve performance for some and worsen it for others. I'm am not sure how the radio software is handled by an Android device, as this is the first one I've owned, but I imagine is is very similar. Just be aware of what you are doing, and how to undo it if something is amiss.
4. There is a thread on this board about unlocking the i897, and as of my last reading yesterday, there is no known way to unlock this phone...yet. There was even a report of someone selling "unlocked" i897 phones on e-bay, which were
later found to be firmly SIM locked. I would advise you read that thread, and be very aware of what you are buying if someone is advertising an unlocked i897.
5. AT&T has blocked (or tried to anyway) non-market apps from installing, and WiFi tethering apps from displaying in the android marketplace. There are work arounds for all of this already.
6. Yes, the are Galaxy S phones with FFC. Not sure if any of them are GSM. Keep in mind that transmitting live video is bandwidth intensive and your plan, and upload speed, may not be robust enough to handle it. On that note, I can find no data that either supports or denies this phone having HSUPA capability which would go a long way towards being able to use a FFC as intended.
7. Your last question is entirely subjective to perspective and intended use.
Were I you I would get the phone that most suits my needs and my HOME network. You may want to wait a bit and see what pans out with this phone.
In Brazil the i897 should not currently be an option you should consider until AT&T has made a definitive decision about unlocking the phones, or a third party solution is possible. The Samsung Galaxy S platform is going to be releases in 110 countries. Brazil being probably one of the bigger cell phone markets, is going to get a variant of the Galaxy S lineup in the near future, you best option will be to wait on a phone like this to be released and then pick it up.
Battlehymn,
Thanks for the answers. I have an expectation when using my phone and now I'm trying to find which phones can fullfill this expectation. That's why sometimes the phone that I (think) want may not be the best for me. I hope i897 will the "the one".
I also think it's the best to think about a phone that will work with 3G on my home state. I897 will work, but as well as i9000. Maybe the best option, as you sugested, is to wait a little to see how i897 works in terms or ROM and unlock.
@rajendra82
Sure. My carrier will start selling the i897 here in few months, but I don't really want to buy it here: An iphone 3GS 16GB brought in a store cost around 3.000 Brazilian reais (around US$ 1,650) while it can be purchased for US$ 400 in the US. I asked a friend of mine to bring me a US phone but I have up to next week to decide which one he should buy.
Thanks
don't buy the captivate if you don't have att you'll be dissapointed because it won't work!
get something that does, if you must get an android device, the nexus 1 with the ATT bands (I think thats what you're looking for?) is you're best bet. they're still available online at places but you are most definitely running out of time
Telstra in Australia run on 850/2100 3G, and I'm pretty sure some networks in Canada do aswell. Keep an eye on on those carriers for a compatible Galaxy S to be released soon.

I have a friend of mine that will travel to US next on august 13th, so I decide which phone I'll bet before he leaves. I don't think there will be Telstra ou Canada versions of the i9000 by than. Will have to decide about buying I9000, i897 or HTC Desire in the next two weeks...
I'm a T-Mobile Prepaid customer using a simple $19 phone but am planning to purchase a no-contract smart phone, say Samsung Galaxy S 2 or HTC Amaze 4G.
If I buy one of these for T-Mobile Prepaid, am I locked in there, or the phone is useful even if I might move onto another carrier such as Verizon or ATT, or to another Plan within T-Mobile later?

No you are not locked in if you buy a phone off contract. You will not be able to move to verizon or sprint with the phone though, because they use CDMA and not GSM like the rest of the world.
you can outright buy the phone, but check to see if they have a pre-paid plan/data plan for that phone, it will not be unlocked so you cannot move. You can request t-mobile to unlock it though, but you will not get the same 4g speeds

Thank you. Does that mean I can use the Samsung Galaxy S2 No-Contract Model I buy from/for T-Mobil Prepaid now for other carriers of GSM? May I understand from your reply message(s) that T-Mobile is a GSM format carrier(and so is AT&T?) as opposed to Verizon and Sprint being a CDMA guys? If so, I can use the phone as long as my next carrier is a GSM guy? Does this make sense?

Thank you. I will do some homework in order to understand what "locked", "unlock" and " . . . will not get the same 4g speeds" mean.
Even unlocked the phone may not support the 3G or "4"G data speed between TMobile and AT&T. The AT&T Galaxy S II will not run on TMobile 3G data, only Edge (2G) data, because they run on different frequencies, same thing with the TMobile Galaxy S II does not support AT&T frequencies. If you buy the phone off contract from TMobile, they should unlock it for you, but there is no guarantee it will work (fully) anywhere else.
If you buy a phone off of craigslist even though you are buying it off contract you cannot guarantee it can be unlocked freely. For example if you buy an AT&T phone used from someone, AT&T will not unlock it for you for free until it's a certain number of months old (based on when the first person bought it from AT&T). You would have to pay a third party for an unlock code (if there is no help here on xda to unlock it).
It's best to just buy a phone for the carrier you plan on using. That ensures its going to work, and that it will work at full speed. If you really think you are going to switch to AT&T buy one of their branded phones, or Verizon etc. Verizon and Sprint both use CDMA, but they are very resistant to allowing another carriers phone on their network. Plus their 4G networks are different types (Verizon uses LTE, Sprint WiMax) so they wouldn't work fully regardless.
Thank you, quarlow.
My budget is around $600 max. So I'm inclined to purchase an HTC Amaze 4Z or Samsung Galaxy S2 for use for T-Mobile Prepaid at Target or at T-Mobile. T-Mobile Net Shop is selling Galaxy S2 Re-Furbished at a discount price. Hear Galaxy S2 have high rate of initial failures and therefore maybe better to buy a re-furbished one that has failed once and was repaired by qualified repairman. Below is how I come to think of buying a smart phone now. I've been happy with a simple prepaid phone buying 100 minutes at a time, which lasts more than a year for me. I also use a Sony Clie, a PDA running Palm Desk Top, which has gone obsolete long time ago. With a smart phone such as Galaxy or Amaze 4Z, I can leave not only the PDA but also a digital camera home. I do not need to access my PDA data over internet. I will import necessary data from my PC to my new smart phone either via cable or via WIFI before going out. That's why I want to remain "Prepaid Customer" not a customer with monthly fees. (Besides, I am not so much interested in leaving my data at ISP's servers.)
Thank you.
I haven't heard of high failure on the Galaxy S II's for TMo. But I have seen several studies showing refurbished devices have lower failure rates because they can have problem components replaced, and have to pass full qa testing twice.
If you are going to put all your data on your phone via USB on the computer, or wifi, then data compatibility won't matter. That changes the whole issue of taking it to another carrier. Any att or TMo phone that is unlocked will make and receive phone calls, text messages and mms messages just fine on the other network. You will only notice the difference when web browsing, or downloading files. If you aren't going to do that, then it wont make a difference.
Knowing that and your budget I would say get a international version of the phone. Get the Galaxy S II (i9100), or the Galaxy Note, or the Galaxy Nexus. All of those phones are top tier, and international versions will receive updates quicker. The Nexus being the Google device will be the first ICS device to get the next version of android, so its the most future proof. The GSM version of any of those phones will likely come unlocked.
The i9100 has a 4.3" screen, and 1.2Ghz dual core Exynos chip. The TMo version has a 4.5" screen (same resolution) with 1.5Ghz dual core qualcomm chip. The bigger screens did have issues with splotches and vertical lines far more than the 4.3" screen. With them being the same resolution the smaller screen is crisper. The Exynos chip is made by Samsung and widely regarded as the better chip, even at a slower speed. It also comes with a more powerful gpu than the qualcomm chip. So, the graphics are better, and games run better. The att version (i777) is almost exactly the same as the i9100, except it has the U.S. norm of 4 buttons, vs the international 3 buttons. The dev support on xda for the i9100 is unmatched by any other phone, its an amazing device with a huge support and user base.
The Galaxy Note is a 5.3" half phone half tablet with a stylus, and 1.4Ghz dual core Exynos chip. Its screen is a whopping 1280x800 resolution. But, for some that's too big.
The Galaxy Nexus has a 4.65" screen with 720p resolution (this screen is pentile which means it doesn't have as many sub pixels as it could. Its hard to explain, Google pentile vs rgb and there should be plenty of explinations. But, most reviews say at that resolution you need a microscope to tell). But the real strength with that device is that its the pure Google device. Its running Android the way its meant to be ran, unbloated and unrestricted. That is the Rolls Royce of Android phones for the next year. The Nexus S is last years Google device, and will be the first gingerbread device with an official ICS upgrade, if it isn't already upgraded. Its like a Mercedes at this point, its got the pure android experience, but its running last years tech: 4" screen, 1Ghz single core hummingbird chip.
I'm sure that is way more information than you ever wanted to know, but I hope it helps.

Att 3G runs on 850 and 1900, with preference on 1900 generally. The TMo looks to have 850, but not 1900. So like the vibrant the support will be spotty at best. It may work in some places, but not everywhere.

To quarlow and lowandbehold -
Very informative! Thank you very much.
I will stay with the plan to go for a Galaxy S2(i1900) or an HTC Amaze 4Z for TMO Prepaid. If there be good prepaid phone service(s) available from other carrier(s), I'd definitely want to learn about.
morning guys
I've seen a few threads about buying in the US and using the N5 in different countries and the fact that although you can use it for 3G/GSM, being able to use 4G LTE is a no go due to the bands that are utilised.
Does/Would anyone know if this is changeable due to the radio being used or would it be a hardware matter as to me it would seem abit odd to produce 2 different phones using the same form factor where a piece of software enabling the bands would be more cost efficient. I appreciate that the software etc is probably being looked at by Dev's now but was wondering if anyone with previous knowledge of this would know.
Only reason I ask is as I'm in the US at the moment (the 32Gb works out considerably cheaper than in the UK) and the area I live in (in the UK) hasn't got 4G (and probably won't have for a while), whether or not to purchase one and then wait for a radio change, but if thats not possible I'll have to go with the expensive UK version
thanks for you help
There are two Nexus 5 models, the D820 (for the U.S) & D821 (for the rest of the world. According to this article by Android Central, it seems that there is a physical difference between the radios installed in each model. So I don't think you would have the option of flashing a radio from a D821 on to a D820 and suddenly have access to UK/European LTE bands. I'm no expert though so maybe others could confirm/deny this.
I too would like to know the same thing (hoping to take advantage of relatives in the US )
However reading around a bit I think it's a hardware limitation. They use the same software on the phones, but they enable the different LTE bands built into the hardware.
Pretty sure no amount of flashing radios will enable the different LTE bands...I'd love to be wrong though.
Shame, even after sales tax the saving would have been worth it. Might have to bite the bullet and buy UK price £££££££££
The CDMA version of this phone(XT1548) is elusive. You cannot order it from motorola.com as it is not even an option. Their customer service directed me to Verizon which is annoying since they do not carry it. Looking at the specs on Droid Life, I tried each carrier site listed for this version. US Cellular is the only company to offer it but they WILL NOT ship it unless your billing address is in one of their tiny coverage cities and in my case it is not even available in my state. Who has this phone and where can you buy it? I want it! Please help if you know, thanks.
Sprint and Sprint MVNOs still do not have any stock or information on their websites yet. Sprint employees don't have any information.
The sooner the better.
To add to this sad news, I noticed that only the 8GB/1GB factory firmware has been posted here which leads me to believe there might not be a 16GB/2GB model available when it does go on sale. I guess we're just going to have to settle for what we can get.
EDIT: On the bright side there are many happy customers with the 8GB/1GB model.
As of today for the Sprint network...
Virgin Mobile (USA) has the XT1548 listed on their site for $149. Will require a year of service before being released. Unlimited data plan is available.
Neither Boost Mobile or Ting have the XT1548 available.
I think I did see the Virgin mobile one but it is only 1gb and I think you have to buy coverage with it, but thanks for the heads up. I am trying out an xt1540 GSM 2gb alongside my moto x which is Verizon unlimited. The moto g is definitely faster smoother, better battery and much better camera but still too big but maybe I'll get used to it. I'm praying the CDMA version will come out in the 2gb flavor on their site and I'll sell this one for it.
Best Buy Here.
thanks so much, just wish they had a 2gb/16gb CDMA model available, but it looks like they did that on purpose. If there was a teardown available for this 3rd gen moto g then I would be tempted to attempt to swap the motherboard and ram from the 2gb gsm model to the 1gb CDMA one. I doubt it would be that easy, but I can always hope...
Why?
Why do you think they did it on purpose?

RAM on phones is soldered down and very small, so you probably won't be moving it from one motherboard to the other. The motherboard also contains the baseband, so putting a GSM motherboard in your CDMA phone would just give you a GSM phone with mismatched antennas.
I'm curious if the CDMA version only has 1GB/8GB to save space on the motherboard for CDMA radio components. I thought this was basically all handled in the Snapdragon SoC, but maybe CDMA requires more components on the motherboard and that's why these other specs suffered? More likely, though, it's just that the CDMA carriers wanted a cheaper price point for the device/higher profit margin at launch.
Hello
I'm looking at replacing my S4 with an S7. My carrier in the US is AT&T and that won't be changing. I've been looking at different unlocked versions and can't find a solid representation of what the real world differences are. I know they have different processors. Some say a band is missing, but does that matter. I don't use android or samsung pay, but i know there is a difference here too. I found one comment about some kind of samsung 'coverage' plan, but what is that?
Best Buy has US unlocked phones for about $700. B&H Photo has an International phone for about $640. Its a lot of money either way. Is one phone really better or different than that other?
I am planning a trip through Canada and maybe to Europe. I assume either would take a SIM from those areas and I could avoid getting raped by international fees.
Here is a summary of question I can think of:
Does the US unlocked phone from BestBuy have a warranty or insurance or anything like that?
Can the US phone be rooted. I only do this to remove apps I don't use.
Is the hardware one vs the other really better or just different?
Does a dual SIM do anything useful?
Does a band being missing make a real world difference?
Is there a good comparison somewhere to that can decide on a phone to purchase?
It comes with a limited warranty as stated on their site:
"This device is not warrantied through the manufacturer. This device has a limited 1 year warranty provided by CCR Warranty. To obtain technical or warranty assistance, please contact CCR Warranty at 866-579-8436."
What I don't know is how useful/limited that warranty is. I'd like the HTC 10 but the unlocked S7 is my runner up, and the warranty issue is one of the major factors in my hesitation.
I do believe it can be rooted.
As far as I know, through research, the only major difference between the two is battery life.
Hello, I'll just go straight to the answers.
1. I'm going to assume that if you go through a carrier (att, t-mobile etc etc.) they will offer an insurance plan. You will have to go to third party insurance for the international version
2. As far I know, the US version does not have a root option yet. Because of the locked bootloader.
3. Hardware will depend on which version you choose. Both are very good.
4. Dual sim is as the name implies, you'll be able to use 2 separate sim cards with their respective #s. that's the only benefit really.
5. Missing radio bands is something you may have to do some research on depending your location.
6. I'm sure YouTube or some online site will have some reviews/comparison of both.
I just looked at the best buy website again and something is different. The S7 listed for $690 is definitely the international version and not the US version. When I looked last month I was positive that the phone was listed as a US phone ... huh
A little late
a little late to the thread but just wanted to share what I learned while researching the matter.
There is an US unlocked version of the S7 (g930u) and available through a few places (Best Buy, B&H, Ebay). It goes for $679.99 retail and I have not been able to find one that goes for less. Probably because it just came out end of June. The biggest benefit of it is that it has a bunch of bands and CDMA-compatible. Thus, you can get full connection with AT&T and TMobile. Downside is no wifi calling or VOLTE (as those seem to be locked by the carriers to their own phones).
The international versions (930f/930fd) are both available on Ebay/Swappa for about $500. Upside are that they have the Exnyos chip and no bloatware. You can also root and flash them with new ROM. Another thing is that you get updates earlier. I got Marshmallow on my s6 a month or so before AT&T released its update. Downsides are no Samsung Pay or WiFi Calling/VOLTE and the biggie...missing bands. I had a g920i and it was missing support for bands 29 and 30 on AT&T...this led to poor LTE and indoor reception at times. I would have to turn on/off the mobile data switch sometimes to get good connection.
Finally, we have carrier based versions, which loads you down with bloatware and has the Snapdragon chip. But, it does support all features of your carrier. Slower updates also an issue and lack of support of all bands internationally are additional drawbacks. Cost is also about $500.
Personally, I am going with an unlocked 930a. Bloatware sucks but I can delete or disable almost all of them. Snapdragon seems pretty powerful to me. Samsung Pay, Wifi Calling, and Band support are just too important for me. Note, make sure you ask the seller on Ebay/Swappa about whether the phone is unlocked.
Hope that helps.
I did a lot of research into this before buying my S7 but was kind of screwed since I'm on Verizon (CDMA)...
Since you're on AT&T you have more options.
There are two different processors in the two different models, Snapdragon 820 in the US CDMA capable and an Eyxnos in the International GSM ONLY phone.
After doing my research, I personally recommend the Eyxnos, which I couldn't get :/
If for nothing else, better battery life, by far. Do some research into the comparison between the two.
However! When buying from Best Buy be careful!
Last I checked, on their website, the black/onyx S7 was an unlocked US Snapdragon 820 phone.... while strangely enough the other two, gold and silver? were both unlocked US (actually international) Eyxnos phones.
Also, last I checked Samsung themselves only sell the CDMA snapdragon processor model to the US.
Unless Best Buy made a mistake listing the Eyxnos processor, it is the only way to get that model without buying an "internationally sourced" phone on ebay.
Just a few notes:
1) The G930u is fully compatible with all the US Carriers
2) VoLTE works on both T-Mobile and Verizon
3) Wi-Fi Calling works on T-Mobile and potentially Verizon (but I am not positive about Verizon).
The big downside to the G930u is that for whatever reason it is not receiving updates from Samsung when its branded siblings are.
