Hearing the phrase 'Galaxy S' builds up a certain level of anticipation these days. But in truth, the Samsung Galaxy S Duos doesn't really merit it, unless you are juggling two lives.The Duos concept isn't a new one, but this is the first time that Samsung has branded one of its dual-SIM phones with the Galaxy S name. The end result is a decent and practical affair, without the 'wow factor' of something like the Galaxy S III.Saying that, it can do something that the Galaxy S III cannot do, which is run two SIMs at the same time. So, for example, you can chat away to a personal contact via one SIM, but still keep up to date and perhaps take an incoming call from a a second SIM. If you need to run a busy home and work life, this could be the phone for you.But hardware-wise, this isn't a match for the Galaxy S III. You'll get a phone with a 1GHz processor, 1,500mAh battery, 4GB of built-in storage, a five-megapixel camera and a four-inch 480x800-pixel TFT screen. The operating system is Android Ice Cream Sandwich. Samsung's ChatON communication service also comes preloaded on the phone.No specific network details or pricing as yet, but Samsung has confirmed this will hit Europe first (including the UK), rolling out from September.
