The Samsung Focus by AT&T is a pretty good phone overall. it has a very plastic feel to it but the screen is very great given that is has a gorgeous 4"Super AMOLED display on it which is very bright. The Samsung Focus runs Windows Phone 7.5 or better known as mango which is a massive update which brings linked emails, multitasking, better integration with social networks like Twitter, Facebook, and LinkedIn, an improved Xbox live app, and many more features. The battery life on the other hand is a little bit of a downer , that Samsug decided to put in is a 1500mah battery and its great in the beginning but slowly starts to wear out and you suddenly see yourself charging the device every 4 hours or so. The Samsung Focus overall is a very good phone just a little hiccups here and there.
