The different chipsets used in the Samsung Galaxy S III phones affect their performances. They both perform excellently when it comes to gaming, multitasking or browsing. However, when it comes to gaming, the Exynos chip has a slight edge due to the dual-core functionality. The extra GB of RAM that the AT&T chip possesses comes in handy only while trying to shift apps very fast.
While on the topic of apps, it should be noted that AT&T has added five apps to the ones already listed on their Galaxy S III phone apart from the basic Samsung apps. On the other hand, the Sprint model includes nine new apps, including a Dropbox app and the Google Wallet app. In this regard, there might be a short lag while using the Sprint version. Audio wise, both phones are terrific, and there is no difference whatsoever in sound quality since neither have made any changes to the original Samsung model.
When it comes to call quality, neither phone disappoints, and you can participate in conference calls easily whilst using the speakerphone! Both Samsung Galaxy S III phones lock onto the GPS network rather fast. It takes the AT&T GSIII model only 3 seconds, while the Sprint model could take up to 7 seconds. That being said, the Sprint model is a tad more accurate when it comes to pinpointing your location.
Both GSIII phones use a standard 8MP rear view camera, and when it comes to picture quality, both models offer similar results. There are some niggles in the Sprint’s model when one tries to use the camcorder function. The Sprint’s camera has some issues while focussing on objects indoors. The same problem persists when you try to click pictures outside in places that have a high dynamic range. The final result is still great though, with top notch clarity. Video recording is also available at 1080p at 30fps, and the quality is far better than any other flagship device out there. Like the HTC One X, both models feature a 2 MP front cam for 720p video calling – which is mediocre but as good as video calling gets these days anyway.
To wrap up, if you’ve already fixed your mind on the Samsung Galaxy S III, then rest easy. Either carrier will give you a phone that performs excellently in every condition. If you are looking for the phone with the better battery life, go for the Sprint model. The same holds true if you love gaming as well. Budget wise, you will end up shelling out the same amount for either phone if you opt for the 16 GB model. If you’re in the mood for phones with a larger internal storage, the AT&T should definitely be your pick. The AT&T model is slightly better when you have multiple apps open and need to shift quickly from one app to another. Either way, you can’t go wrong when you’ve selected the SIII! You can pre-order the AT&T Samsung Galaxy S III starting at $149.
