One of my favourites ~ Samsung SideSync has updated to version 3.0. And it does not limit to Samsung ATIV Windows PC anymore. Yes, all PC with Windows XP SP3 and above are supported. However, you need to have Samsung mobile devices with at least Android 4.4 KitKat in order to use SideSync 3.0. Err… My Galaxy S4 still not updated to Kitkat yet. Maybe this will be the reason to do so?
