Introduction to mainstream mobile phone operating systems-mobile phone platforms

I,Windows MobileOperating System of Series Mobile phones

Windows Mobile operating systems are changed on Microsoft's Windows operating system. Therefore, their operating interfaces are very similar, A friend familiar with Windows operating systems generally recognizes windows mobile operating systems as Microsoft. Most windows mobile operating systems have more powerful functions, including audio, video file playback, surfing, MSN chat, and email sending and receiving. Moreover, many smartphones that support this operating system use intel embedded processors, with high clock speed. In addition, smartphones using this operating system have much higher performance than smartphones using other operating systems in terms of other hardware configurations (such as memory and storage card capacity, the operation speed is faster. However, this series of mobile phones also has some disadvantages, such as high power consumption due to high configuration and many features, short battery life, and high hardware cost. Windows Mobile operating systems include smartphone and Pocket PC phone. Pocket PC phone is mainly used for Handheld smart phones, while smartphone provides OS for single-handed smart phones.

(1)SmartphoneOperating System

Microsoft smartphone is an operating system developed by Microsoft Based on the Microsoft Windows CE kernel for smartphones. Unlike a smartphone that uses a pen for operations, A mobile phone based on the operating system can complete almost all operations without the help of a pen. Therefore, a mobile phone user using the operating system only needs to perform one operation by one hand. Smartphones based on the smartphone operating system are not very different from other Microsoft operating systems in terms of functions. Most of them have functions such as MP3 playback, MSN chat, and email sending and receiving, you do not need to use a pen to perform operations. Currently, smartphones that support this operating system have reached Mio 8390 and Mio 565.

(2)Pocket PC phoneOperating System

Pocket PC phone is currently the most common Microsoft smartphone operating system. Most smartphones on the market currently use this operating system based on Microsoft OS, for example, the familiar smart phones such as Lenovo et180, et560, dashboard 696, dashboard cu928, and dashboard use this operating system. Unlike Microsoft smartphone, the operating system uses a pen to complete most operations.

II,SymbianOpen Operating System

The Symbian operating system provides a flexible application interface (UI) framework, which not only allows developers to quickly master the necessary technologies, but also enables mobile phone manufacturers to launch products with different interfaces. Mobile phones of the Symbian system can adopt multiple application interfaces: one is designed to be similar to the most common mobile phones, that is, the mobile phones that are input through the keyboard; the other is the mobile phones that use the pen for operations; there is also a type of mobile phone with both a keyboard and a touch screen. It has a large screen and a small keyboard. Different Input Methods and designs will have a great impact on the main use of various mobile phones. The requirements of the application interface are determined by mobile phones and the market. With the Symbian operating system, mobile phone manufacturers and third-party developers can develop unique application interfaces for the above types of mobile phones, such:

(1) Mobile phones with a digital keyboard (Symbian s60)

This type of mobile phone requires a flexible application interface for users to use the joystick, soft buttons, or jogdial buttons for operations, nokia 3650 and N-gage represent that they use the Series 60 application interface. Such as Nokia 6600, Nokia 7610, and Nokia 6670;

(2) Mobile phones with touch screens (Symbian uiq)

This type of mobile phone mainly uses the uiq interface, which is represented by Sony Ericsson P802 and p908. Uiq is a customizable application interface based on Pen input. It is suitable for mobile phones with rich multimedia features.

(3) Mobile phones with full keyboards and ultra-large color screens (Symbian S80)

These mobile phones provide advanced mobile communication functions for users who need to edit information and view business data outside the office. The Nokia 9300-9500 Personal Communicator series are typical examples of such application interfaces.

III,PalmMobile operating system

Palm is a 32-bit embedded operating system developed by the palm computing department of 3com. It was originally a company that mainly produces handheld and handheld operating systems, the palm operating system used by the palm smartphone is very similar to the operating system used by the Palm handheld computer. Therefore, there are many third-party software on the mobile phone based on the operating system, in the past, users who used to use Palm handheld computers were able to quickly master such smart phones.

Because palm has always followed the concept of less is more (less is more) to design, it is different from Microsoft's operating system that occupies a large amount of system resources and storage capacity, it occupies a very small amount of memory, and applications written based on the palm operating system occupy a small amount of space, usually only dozens of kb, therefore, although the palm operating system-based handheld computers only have a few megabytes of memory, they can run a large number of applications. However, as a result, there are not so many features. Of course, recently, palm seems to realize that rich features are very attractive to consumers. Therefore, palm also seems to be moving closer and closer to providing rich functions. The concept of "less is more than more" is gradually weakened. In addition, for Chinese users, its disadvantage is that its operating system still needs to use a Chinese plug-in platform for products originally sold in China, A considerable number of products are still based on the English interface, which affects the large-scale entry of palm-based products in the Chinese market to a certain extent. Currently, mobile phones based on the palm operating system are Samsung SPH-i330, Handspring Treo 650 series.

IV,LinuxMobile operating system

Like windows mobile operating systems, Linux mobile operating systems are "changed" by computer Linux operating systems. In short, Linux is a free-to-use and free-to-spread operating system. It supports 32-bit and 64-bit processors. In the computer field, it is mainly used for computers equipped with intel X86 series CPUs. in the mobile phone field, Motorola a768 is a representative product.

Linux is stable, reliable, secure, and has powerful network functions. With the support of related software, services such as WWW, FTP, DNS, DHCP, and e-mail can be implemented. Since Linux is open source code, this feature is very important, because a wide range of applications are the embodiment of the superiority of smart phones and the key selling points. From the perspective of application development, because the source code of Linux is open, it is helpful for independent software developers (ISVs) to develop application software with high hardware utilization efficiency and more powerful functions, it also facilitates industry users to develop their own secure and controllable authentication systems. Especially when smartphones are widely used as mobile terminals for industrial applications, Linux has also emerged in the mobile operating system market and has become a force that cannot be ignored. At present, based on Linux mobile phone operating system products are Samsung mitssch-i519 and Motorola a768, a780, e680 and so on.
