Summary: This is a terrific phone, I'm a first time smart phone/touch screen user transitioning from a blackberry 9780 and I really found the interphase really user friendly.

Conclusion: Samsung galaxy s2 is a nice android phone by Samsung. It has several number of applications and features like 8 mega pixel camera, 1 GB RAM and front camera also. The battery life is up to the mark. One of my friend has it and she says this gives a lot of hanging problem.
Conclusion: Samsung Galaxy S2 Plus has the same look as the original but with upgraded internals. With the lack of a true mid-range device from Samsung (though the Galaxy S3 will assume this spot as it decreases in price after the launch of the S4), it presents an attractive option.
Excerpt: Among the different choices available out there, I choose to go with Samsung. This is because I love the brand and the product it designs. I have not used the first S2 so I do not know about its performance. But the second one is simply the best that one can go after.
