The Samsung Focus S is running Microsoft’s latest Windows Phone 7.5 operating system. If you haven’t already, be sure to check our our Windows Phone 7.5 review for all of the details and new features that it brings. Of course, Samsung has done some customizations and AT&T has bundled a few AT&T branded apps as well, so that’s what we’re going to look at in the below video. You’ll also see what kind of customizations Samsung has done to the camera. I like the “wide dynamic range” option, but it doesn’t have anything comparable to what HTC has done with the panoramic and burst shot photo options. We’ll also take a look at what kind of speed increase you might see in some of the games. For the most part the Focus S might seem just as quick as last year’s Windows Phones, and it is, but you’ll see there’s definitely a speed increase when loading processor intensive apps and games.
