Samsung Galaxy S II VS iPhone 4S 3

Samsung Galaxy S II and Apple iPhone 4S are two high-flying smartphones out in market today. The Galaxy S II has arguably been the best Android smartphone since its release early second half of 2011. On the other hand, iPhone 4S is the most recent upgrade to Apple’s flagship smartphone iPhone.

When the Galaxy S II runs Android 2.3 Gingerbread, the iPhone 4S dominates the market with the latest iOS 5. Indeed, these two devices now represent the so-called battle between Android and iOS platforms, which kicked off when Samsung brought out its original Galaxy S phone in 2010 in competition to the highly successful iPhone 4. Here is a brief comparison between Galaxy S II and iPhone 4S under some common parameters.

Form Factor

When it comes the form factor, Galaxy S II is enjoying a clear edge over iPhone 4S. The Samsung phone is one of the slimmest smartphones with a thickness of 8.49mm. The new Galaxy S phone rocks the dimensions of 125.3 x 66.1 x 8.5mm, while iPhone 4S has the same 115.2 x 58.6 x 9.3mm dimension of its predecessor, iPhone 4.


Galaxy S II sports a large 4.3-inch Super AMOLED Plus display with a resolution of 800 x 480 pixels. It has been one of leading smartphones with a large screen. It is when iPhone 4S stays there with the typical 3.5-inch of all its predecessors. The new iPhone’s screen is made of IPS LCD technology and it features 960 x 640 pixel resolution. There are lots of Apple geeks, who constantly demand Apple expand the screen size of its iPhone. Indeed, the next iPhone 5 may come with a large 4-inch plus display.


You have a powerful dual core 1.2 or 1.5GHz Cortex A9 Exynos 4210 SoC processor inside the Galaxy S II, which is muscled up with a 1GB of RAM and ARM Mali 400 MP GPU. In the meanwhile, iPhone 4S comes with a 1GHz dual core Cortex A9 processor with Apple’s famous A5 chipset. The PowerVR SGX543MP2 GPU wins iPhone 4S in graphical performance.


Galaxy S II is one of the first smartphones to get an 8-megapixel rear camera. It helps you capture video at Full HD 1080p at 30fps with additional capabilities like auto focus, LED flash and geo-tagging. For video chatting, the Galaxy S II sports a 2-megapixel camera. The iPhone 4S also mounts an 8-megapixel camera with 3264 x 2448 pixels, CMOS illuminated sensor and 1080p HD video recording capability. But it has only a VGA camera in the front for video calls.

Samsung designed its Galaxy S II to take on the 2011 version of iPhone. As Apple delayed release of its iPhone 4S until late last year, the Galaxy S II had been fighting iPhone 4 on market for some months. With the arrival of iPhone 4S, there came out many other high-end Android smartphones like HTC Rezound, Motorola Droid RAZR and others. In fact, the significance of Galaxy S II deteriorated. Now the Korean tech maker is busy working on its next Galaxy S III for this year to defend the iPhone 5 challenge from Apple.

    I’m not an Apple fanboy, but it does look like the iPhone 4S is the better device, the same way the S2 was better than the iPhone 4, and the same way the Galaxy S3 will be better than the iPhone 4S. Apple and Samsung are besting each others by turn at this point.

    I use Galaxy S II as it more cost effective. But no doubt iPhone 4s is more popular

    Galaxy S III is even more impressive. I’ve been lucky to study it carefully. No words. The friend who bought it asked me for a review. I can’t really say a word. It’s perfect. Now I just wait the iPhone 5 and I will choose carefully which one to buy.
