Samsung Galaxy S3 vs Galaxy S2

The Samsung Galaxy S 3 is the company's new Android flagship and it features a quad-core processor, a 4.8" 720p screen and an 8MP camera packed in a 8.6mm body (no chins this time).

Samsung Galaxy S III runs Ice Cream Sandwich with Samsung's latest TouchWiz interface that includes cool new ways to interact with the phone - S Voice (a direct Siri competitor), eye-tracking (Smart Stay) and several other clever tricks, which the smartphone has up its sleeves.

And, if you don't need to be quite on the bleeding edge of smartphones (and paying through the nose for it) then then Galaxy S 2 may well be enough for you. OK, here is a brief comparison between Samsung Galaxy S 2and Galaxy S 3.

To start with, both the Galaxy S2 and the S3 run Android, but different versions. Samsung Galaxy S2 uses Android 2.3.4 (Gingerbread), customized with the TouchWiz 4.0 UI overlay and Swype text input. It's upgradeable to Android 4.x -which the Galaxy S3 comes with by default - Android 4.0.4 to be precise.

Samsung Galaxy S3 vs Galaxy S2

Both handsets have Samsung's 'hub' apps in common including the Social Hub, the Games Hub and the Music Hub.

And with respect to processing speed, The Galaxy S2 was one of the first handsets to feature a dual-core processor. Inside the S2, you'll find an Exynos processor (formerly 'Orion'), rated at 1GHz. This was the dual-core follow-up to the successful single-core Hummingbird chip that appeared in the original Galaxy. The S3 by contrast ups the ante to quad-core with a new chip called the Exynos 4 Quad - it runs at 1.4GHz.

There are performance improvements over the earlier Exynos processor also the quad-core processor consumes 20 per cent less power.

Super AMOLED and Super AMOLED Plus:

The Galaxy S3 takes Super AMOLED to a new level with an HD, 1,280 x 720 screen. While it's half an inch bigger than the S2's 4.3-inch, 800 x 480 display, there's no Super AMOLED Plus tech used unlike the S2. But the S3's display has to be seen to be believed and, while the S3 seems to dial down Super AMOLED's massive colour saturation, it's a terrific screen.

Storage and memory

The Galaxy S2 comes in either 16GB or 32GB models, while the S3 also adds a 64GB model to the list. Both feature 1GB of RAM. And both the models support microSD card.


Samsung Galaxy S3 is an 8 Megapixel camera with extras that include: autofocus, LED flash, geo-tagging, touch focus functionality, face/smile detection, image stabilization and 1080p video capture (the S2 also had a 8MP unit). The front camera actually takes a step down - you'll find a 1.2MP 720p camera in the front of the S3 for video calls or self-portraits while the S2 had a 2MP unit. The S3 is also capable of full 1080p HD playback, and I guess S2 can also do the same with regard to HD playback.

Cameras aren't all about megapixel count, and both the rear and front cameras on S3 will be improved massively, especially in low light conditions, and hopefully during recording videos in lower light, the S2 suffered slightly grainy footage in low light. Having said all of that, the general consumer seem to take megapixel count as an example of how good the camera is.


In terms of connectivity, both phones are well-specced. The Galaxy S2 and S3 incorporate 3G/HSDPA and HSPA+ at speeds up to 21Mbps where supported. It's got every band of Wi-Fi covered too and can handle 802.11a/b/g/n with DLNA content sharing and Wi-Fi Direct.

Bluetooth 3.0+HS finishes off the wireless options in the S2, while you get the new and more power efficient Bluetooth 4.0 inside the S3. The S3 can also use MHL to output to a monitor via its micro USB port.


Both these Smartphones feature GPS/A-GPS, a built-in gyroscope, digital compass, plus screen-flipping accelerometer, proximity and light sensors. And the S3 adds a barometer.


Like the Galaxy S2, the new S3 is a neatly designed, beautiful-looking handset that measures 136.6 x 70.6 x 8.6mm compared to the S2's 125.3 x 66.1 x 8.49mm. Yes, note the size has gone up across all the dimensions, but the plastic remains which means the weight doesn't reflect the bulk. The S3 weighs in at a respectable 133g compared to the S2's 116g which, if you've held one, you'll have thought was very light indeed.


The Samsung Galaxy S2 boasts a 1650 mAh battery, while the S3 has a 2100mAh battery. Because, bigger screen and quad-core processor need a lot more juice, so the bigger bulk is no doubt down to the bigger battery inside the S3.

Final Words:

There's no doubting that the S3 is a terrific new handset and it seriously ups the ante on the ageing S2. However, it depends whether you're prepared to pay for the privilege of owing a new model handset.
