What is a smartphone?

Smart Phone (Smartphone), is "like a personal computer, with a separate operating system, users can install software, games and other third-party service providers to provide programs, through such programs to continue to expand the function of mobile phones.

    Nowadays, with the development of technology, smart phones have become a necessity for life. I believe that many netizens will bring their mobile phones wherever they go. Even if there are no calls and text messages, they will play games,facebook, whatsapp or WeChat.

 Smartphones are simply open and independent operating systems. In addition to the mobile phone's calling function, users can also install mobile phones such as software, games and other third-party service providers. Like a personal computer, a smart phone has an independent operating system and an independent running space.

   Users can install programs provided by third-party service providers such as software, games, navigation, etc., and can realize wireless network access through a mobile communication network.

   The scope of smartphones is already covered all over the world. Because smartphones have excellent operating systems, freely installable software, and full-screen full-touch operation, they completely ended the old Keyboard phone.

   At present, most mobile phone manufacturers in the world have smart phone products, while Finland's Nokia, American Apple, Canada's RIM (Blackberry), American Motorola, and Taiwan's HTC (htc) are the best in the smart machine. Among them, Apple, Samsung, Nokia, HTC are the four most widely known brands in the world, while China's Lenovo Lenovo, Huawei HUAWEI, Xiaomi Mi, BBK (VIVO), ZTE ZTE, Cool Coolpad, Meizu MEIZU, Opal OPPO Gionee Gionee and Tianyu (Tianyu) K-Touch top ten brands are receiving much attention in China.

  A smartphone is a mobile phone with an open operating system installed in the mobile phone. By the end of 2008, there were about 450 million. Commonly used operating systems are: Symbian, Windows Mobile, iOS, Linux (including Android, Maemo, MeeGo, and WebOS), Palm OS, and BlackBerry OS. The applications between them are not compatible with each other. Because third-party software can be installed, smartphones have a wealth of features.
