Google Android's competitors will never be Motorola or Sony Ericsson. Android wants to build a mobile operating system and a software empire for mobile products, now, Google is able to access Nokia's Symbian and Microsoft's Windows Mobile. <Br/> Nokia's strength is not unreasonable. Symbian is not technically superior, but its East Nokia is the world's largest mobile communication device manufacturer, in short, there are sales and markets, and its Symbian will naturally gain a huge market share, which is somewhat cool. At this level, Windows Mobile and Android are similar. They are mobile products that only work on software and do not have sufficient advantages. <Br/> Android is busy drawing on mobile phone manufacturers like Motorola and Sony Ericsson that have been pressed by Nokia for a long time. It makes it clear that you were pressed by Nokia because you didn't have a strong operating system or software platform, but now all these problems are solved by Google. You only need to do your mobile phone well and do other things. Therefore, Android-based mobile products have sprung up recently, and the policy for Android is effective.
