The Samsung Galaxy S II is the phone the Korean firm deems the successor to its best smartphone so far. And with a 1.2GHz processor, super-slim chassis and feather-light innards, it's easy to see why.

The dual-core race is set to heat up massively over the next few months, with the LG Optimus 2X already released, and the Motorola Atrix, HTC Sensation and iPhone 5 all set to bring the tech to market too.

The success of this smartphone...

The 4.3″ Super AMOLED Plus is nothing short of amazing!

Super AMOLED Plus technology is the best available technology for mobile displays. The images are sharp, blacks are true black (no backlighting) and colors are eye popping . It can make almost anything look better on the screen. Unlike the previous generation SAMOLED screen equipped in Galaxy S, sAMOLED+ consists of conventional RGB matrix, which makes the display sharper as well – you can even read the smallest of text.

As Samsung is the only manufacturer of Super AMOLED displays, you need to make a choice. If you want to experience the best screen there is no other choice in the market (not forgetting Nokia’s Clear Black AMOLED which is also promising but the current devices with Symbian or Meego platform doesn’t have a bright future as Nokia officially embraced WP7). Also, the 15:9 aspect ratio of the device is more suitable for playing HD content than the 3:2 aspect ratio of iPhones.

Processing power, RAM, Storage and others

Galaxy S2 is equipped with Samsung’s own Exynos processor (previously know as Orion) which is a dual core processor based System on Chip (SoC) with with a clock speed of 1.2 GHz. It is backed by a Mali 400 GPU and 1 GB of RAM. This is almost equal to the processing power of a desktop machine. The result is, you can play even full HD videos smoothly.

The phone is equipped with 16/32 GB of internal storage (though the 32 GB version is yet to be released) and comes with a micro SD slot to extend the storage up to a whopping 64 GB (32 GB + 32 GB).

In addition to a GPS receiver, proximity sensor and accelerometer it also includes a gyroscope for optimal motion tracking.

Excellent Connectivity

Samsung Galaxy S2 comes with amazing connectivity options. It does support 3G data speeds up to 21 Mbps (HSPA + networks), Bluetooth 3.0+HS transfer, Wifi Direct, Allshare (DLNA) and HDMI through MHL.

Unlike Apple iOS, where you can’t even transfer the pictures taken with the camera through bluetooth, there is no restriction here. You can transfer files through highspeed Bluetooh (it is the only device at present that supports true 3.0+HS standard), or Wifi Direct. Using Allshare, you will be able to stream multimedia content wirelessly to any device that supports DLNA (you can use XBMC media center software in your computer as well). Kies Air enables you to manage the phone content wirelessly without any software or driver. It also supports Usb on-the-go so that you can connect other USB storage devices directly to the phone.

Excellent Camera

The 8MP camera sensor can capture full HD videos (1920 x 1080px) and good quality images. It may not be the best camera (Nokia N8′s 12MP camera is still the best camera equipped in a mobile), but definitely one of the better mobile cameras. Samsung also listened to the users’ feedback and added an LED flash (at least it can be used as an emergency torch light).

Responsive UI

Samsung finally made the TouchWiz UI right. It was a bit buggy on the Galaxy S, but the new TouhWiz 4.0 is stable and usable. Because of the extensive processing power, the UI feels very responsive and fluid. My Galaxy S2 didn’t hang even once since I bought it (more than 1 month) while my friend’s Galaxy S is hanging frequently.
