In the evolving mobile phone and smartphone market the operating system (OS) is becoming one of the most important aspects to consider. Indeed, by selecting a particular OS, the phone experience will be very different, as will the applications and possibilities that are linked to that choice.

In this test, we have selected several devices that work under different operating systems. In the current market, there are six different OS: iOS, Android, BlackBerry OS, Windows Phone 7, Symbian and Bada, each with their own specifications. The goal of this test is to see how well the OS is designed, how easy it is to use, and how versatile it is.
