Looking for trusted information about what smartest smartphones are, I found that most references I read seemed to agree that there are two leading brands competing to be smartest. Samsung with its Galaxy S III and Apple with the iPhone 5 always appeared on the pages of top smartphones I visited. Is it the fact or just the effect of their popularities? Well, you should decide by yourself because you may have your own opinions about what you hold on your hand as a user. However, it must be great to see some brands with different smartphones.
