I've purchased a generic netbook running on Android. I'm unhappy with it for a number of reasons, but it was sold as being Android 2.1, yet when I look in Settings > About device > Firmware version, it says "1.6". Is "Firmware version" the same as "version of Android"? I just notice that my Android phone has different menus (Settings > About phone > Software information > Android version) and am worried that the seller is going to argue that "Firmware version" is <> "Android version". Apart from this field, is there any other way of definitively establishing which version of Android the device is using? Thanks!
