Stephen Elop, CEO of Nokia, says the main reason of Nokia’s failure is the popularity of Android.

Here is what the China case says:

A good example of this is the CDMA technology in China, where that technology has seen quite an increase in market share in China. And as you know, we don’t currently have CDMA products, but clearly, that’s something that we’d be considering in the future. So there’s some dynamics like that that we have to deal with.

As for the European market, the main reason is called to be the price of the devices:

In Europe, that’s not the case on the management perspective. It’s very much about competitive pressures. We’re seeing, for example, a large volume of Android devices really coming into the market. They’re largely undifferentiated from one another, which is putting pricing pressure thereupon, which in turn affects the overall ranging decisions of the operators; so there’s definitely pricing pressure going on.

Unfortunately, I don’t really think that these are the only regions that Nokia has to worry about. The fact that they had to close up a few stores in the U.S.  is also bothering. So where is Nokia going to distribute its devices if not even in Europe?
