I just love the Chinese phones they are so so much better than the English phones
I saw a phone about a year ago which was a phone on the front then when you turned it over it was a proper camera the zoom on it and the features where like you was holding a little camera in your hand
They use very cheap parts for constructing these phones and labor in China is one of the cheapest in the world. But I don't vouch for their quality. But if you are satisfied with phones of mediocre quality then you can buy one.
There's biggest population in that country, therefore labor cost is of course attractive, and since the labor cost isn't high, the raw material while purchasing won't be that high either. Further more, in the country many people don't care about the brand that much, they just like to buy copied stuff which they believe would work just good. And yea they are talented of course, because it's also a kind of technology to produce something which they haven't made before.
