Samsung Galaxy S4 i9500 Factory Unlocked Cellphone, International Version, 16GB, Black

Where do I begin? I upgraded from teh HTC Sensation, and the increase in performance is great. The phone does not break a sweat running apps, and there is a lot of memory so there no noticeable lag in performance. Mind you I have the quad core version from Tmobile. The screen itself is large, and very bright. There is a tinge of blueish-green when it is not lit up, but other than that, it is clear and I can't ask for more. It is though, a little large in the hand, with my thumb not being able to get across the whole screen, so if you think that you have small hands, you may want to hold it with both hands. Some people may complain of the polycarbonate body, but it is pretty sturdy and feels good in the hands. It also lends to the fact that the phone is light, very light for its size, and if the case is broken or dented, it should be relatively cheap to repair. Consider replacing a phone that is sealed, and how difficult that may be. The phone requires a micro sim, and it does come with a port for an SD card which if you own the 16gb version, you will be using. Samsung has loaded this phone up with some cool features, but nothing you can't already get. If you do not want the extra features, I would wait for google to release their version of the SGS4, which is going to be running a stock version of android. On to battery life. It is awesome. I am an average user. This is my primary phone and I talk about 2-3 hours on it daily. I surf the net, watch Netflix for roughly an hour, and text a lot. I keep the bluetooth and wifi running 24/7, and have disabled all of the sensors that I believe are a waste. That being said, the battery gives me roughly 12-14 hours a day, with me unplugging the phone at 7:30am and plugging it back in around 11pm, and still having 20% of juice left. I've mentioned the sensors.... I think that air view and air gesture were a little rushed. They really IMO do not work as advertised. Good effort, but needs a lot more work, and if you have them enabled, battery life is taking a hit. The internal speaker is what can be expected of any phone speaker, loud and a little annoying, but as I said, what can you expect out of it. That said, I think that the iphone speaker is a little better. Connectivity wise, I have very good reception with this phone, 4g anywhere I go, bluetooth works flawlessly, and gps is perfect reception. Wifi also is really good, with fast speeds. Call clarity is very good, especially if you are tmobile to tmobile, and if your phone supports HD calling. I definitely think that call clarity is a lot better than that of the iphone, which,whenever I speak to anyone who owns an iphone, it always sounds somewhat muffled. As for Samsung's TouchWiz, I've heard a lot of people bash it, but it really works pretty well. Layout is pretty well thought out, and to me, it makes sense. You really can't go wrong with it, unless you are an Android purist, in which case you can wait for the stock version to be released.

Pros on getting gti9500 1) Galaxy s4 gti9500 is indeed very fast, it does not run 8 cores at once but alternates between the 1.6 Ghz cortex quad core and 1.2Ghz cortex quad for efficient performance and in real life ,its battery is about 20% more lasting than the i9505 version. 2) The camera in gti9500 is more advanced (the exmor RS) compared to the exmor R in gt19505 version, giving better detailed shots and enhanced images in low light conditions 3)The GPU in gti9500(PowerVR SGX 544MP3) is different from the GPU in gti9505(Adreno 320) , its graphic options are set at a higher level than the adreno 320 but the frames per second on both GPU is around average and in actuality , the adreno 320 gives better fps for low end graphics games. Cons 1) LTE standards are not supported by the gti9500 version, though the exynos 5 chipset has the capability to support all LTE bandwares as mentioned by samsungexynos5 on twitter, the exynos 5 does not support LTE standards, so the closest non wifi data you will have is 3G, HSPA+ 2) Only GSM mobile companies will work on 3) Warranty; warranty is only valid if get it checked in the same country from where you got it, if your from US and break your gti9500, Samsung US will not accept your device to repair, hence either you get insurance for your phone or you just get the phone that is available in your country. That being said, the S4 does have gorilla class 3 and the back does not break easily , my own gti9500 is holding up quite well. If your doubtful on buying the gti9500 online, be rest assured that it is indeed just as described , brand new and factory unlocked. The shipping is also fast( based on my personal experience) any queries on which company to choose to buy the s4 from , i would suggest those companies which are Fulfilled by amazon.

The MAIN reason I changed my old smartphone -Galaxy Ace, which is a nice turtle- was based on the processor speed factor. The fastest one on the Galaxy family is the S4 and this is why I got it, but honestly the speed I was expecting to get is not too much noticeable. I'd hate to conclude that smartphones are lazy devices, so I won't do so. I'm not there yet. I guess that dealing with these beauties is a matter of patience, most of the times. Nope, I don't have installed tons of apps and games in my S4; I'm not one of those users. For me, a cellular phone is... a phone, basically. So I installed just 5 or 7 smart tools for my daily tasks, but that's it. And those tools are not heavy ones like those applications out there that require enormous resources from the OS or the processor for their operations. So this is not the reason that makes my S4 a bit lazy. But anyway... One of the aspects that professedly are one of the "great" features of this phone is its huge screen size. For some people this can be awesome. Well, sorry; not for me. Why? Just because you would need giant hands and an extremely elongate thumb to reach the entire area of the screen. So even if you have big hands like me this is not a comfortable phone to operate with one single hand (as I used to do with my Galaxy Ace). Now don't say "get a smaller phone then!". Please go back and read my first paragraph... Regardless of what I have mentioned above this is a great phone and I am happy with it. I guess this is a matter of a 'getting used to it' process. JAS

el cargador que enviaron con el producto no sirve, se sobrecalienta y nunca carga :(

works well, great price, easy instructions, arrived fast enough

I have very much satisfied with Samsung Galaxy S4 I9500

El producto no es completamente nuevo , había fotos en el teléfono que no deberían existir si es brand new adicional no se menciona que es de un operador en especifico lo que no me deja hacer updates o upgrades de sw. No lo devolví por la necesidad que tenia del telefono. Terrible.

Hong Kong version which i s id not know i was getting. When the Phone arrived looks great but the phone never worked. When making calls i can hear the person on the other end but they cannot hear me.
