Let me put it briefly,

The Symbian system is a mobile phone of Nokia. This system is a fully closed system. Its system cannot change the system content of the machine, so No playability. Why is the brand so famous and sales so good? That is, he produces mobile phones from the lowest to mid-to-high-end.

The windows mobile system is mainly produced by HTC Dopod, headquartered in Taiwan. They produce all-smartphones, high-end products, and people who don’t know much computer knowledge can’t use it at all. This system is the same as a computer. Yes, you can see all the files of the system on the C drive of the computer. The same goes for the mobile phone. The computer can change the system, and the mobile phone can also change the system. In short, it is a handheld computer. This is OK to understand. What the computer can do is, it Generally it can be done. The reason why the brand is not popular is that they are all high-end products with high prices, which ordinary people cannot afford.

The Android system is a system developed by Google. HTC mainly produces hardware and Google provides system software support. This system is a fully open system, very playable, and is also a future development trend.

In short, Nokia is the worst in terms of intelligence, and is semi-intelligent at best, because the closed system determines it, while the other two systems are world-class in terms of intelligence.

There are basically no new touch-sensitive mobile phones in 2010 that cost around 2,000 yuan. For a few hundred yuan more and less than 3,000 yuan, you can buy a G3, a Google system, which is very popular now and very tasteful, or you can buy a The Diamond 2 generation of WM system is very good and powerful.
