The image you’re looking above is in all likeliness, the Galaxy S II Plus. Renowned Mobile analyst and editor of site Mobile-Review, Eldar Murtazin posted this image on his Twitter feed and though he did not explicitly mention the name, he did somewhat confirm the device in another tweet.
Existence of Galaxy S II Plus came to light after the benchmark score of the device was leaked. The phone as you can see is strikingly similar to the original Galaxy S II but sports touch-sensitive menu buttons. It is also said to sport a faster dual-core processor clocked at 1.5GHz, will run Android 4.0 with TouchWiz and will have a WVGA display.
Let’s hope this image is real and is showcased at the MWC later this month.
