When people are talking about Samsung's upcoming smartphone Galaxy S4, Samsung's other devices under the Galaxy series -- Galaxy S3 and S2 are busy getting Android Jelly Bean updates.

The Galaxy S2 comes with a 4.3-inch SUPER AMOLED Plus display and a dual-core Application processor. The smartphone is said to be the device which really gave a boost to Samsung's dreams of making a presence in the global samrtphone market.
