, Regarding the various operating systems of mobile phones. There are many questions. I hope professionals can answer them one by one!

There are seven mainstream systems, including Symbian (Symbian), Linux, Palm (Personal Digital Assistant), BlackBerry (BlackBerry), Windows Mobile (Microsoft), Android (Google's Android), and iOS , (in no particular order) there are other systems

symbian

The brand equipped with Symbian system

It is also called EPOC system, which is the earliest An operating system developed by Psion Company specifically for mobile devices such as mobile phones. The symbian system mainly has two platforms, namely Series and UIQ for handwriting smartphones. Symbian is currently supported by mobile phone giants such as Nokia, Sony Ericsson, Panasonic and Samsung, accounting for 41.2% of the smartphone operating system market. The current highest version is Symbian 9.5. Its representative models include Nokia N73, N80 and Sony Ericsson W958C using Symbian 9.1 system, Nokia N70 and N72 using Symbian 8.0 system, Sony Ericsson P802P908 using Symbian 7.0 system, Nokia 6600, and Siemens SX1.

Symbian operating system fully supports Microsoft Word, Excel and PowerPoint files, but whether you can create or edit these documents ultimately depends on your phone's hardware. Symbian's support for email is definitely no worse than other operating systems. The advantage of Symbian is that it is supported by handheld communication equipment manufacturers that occupy the majority of the market share. Under the strong advocacy of NOKIA, it has become an open, easy-to-use, and professional development platform. Third-party applications on the Symbian operating system There are the most software and games in mobile operating systems, and installation is also relatively easy.

Symbian's office features and multimedia features are constantly improving. It is a qualitative leap from the Symbian7 era to only support mono output to now support Bluetooth stereo. Thanks to Nokia's powerful promoter, Symbian has become the most popular operating system and the one with the highest recognition among users; and as more and more smartphones use Symbian, it will surely attract more customers.

Linux Relying on its advantages of freedom, free and open source code, through the efforts of programmers from the Internet and all over the world, coupled with the support of computer giants such as IBM and Sun, Linux has become the most popular mobile operating system in the world. A new force has emerged in the market, especially after many well-known manufacturers announced their support for Linux mobile operating systems. The development of Linux cannot be ignored.

Because Linux has the advantages of open source code, low software licensing fees, and abundant application development talent resources, it is convenient to develop personal and industry applications. This feature is very important because rich applications are the superiority and key selling point of smartphones. From the perspective of application development, since the source code of Linux is open, it is helpful for independent software vendors (ISVs) to develop application software with high hardware utilization efficiency and more powerful functions. It also facilitates industry users to develop their own safe and controllable software. Authentication system. Especially when smartphones are widely used as mobile terminals for industry applications, using Linux facilitates the implementation of system-integrated security strategies.

Linux’s entertainment performance is also relatively powerful, supporting multiple audio and video formats such as MP3, WMA, RM and AVI. Currently, there are relatively few third-party software suitable for Linux systems, but the basic software is available. Typical representatives of embedded Linux systems are Motorola’s smartphones E680i, A1200, etc.

Linux system is an open source operating system, and there are already many popular versions. But compared to the ones introduced earlier. The system has not yet received wider support.

Motorola has always attached great importance to the research and development of Linux mobile phones, and recently it plans to make 60% of its mobile phones run the Linux operating system in the next two years.

Open source software is gaining popularity because the Linux operating system can reduce costs for mobile phone manufacturers.

Linux software is a potential platform for mobile phones. Its emergence is only the cornerstone of open source. Its popularity on mobile phones still has a long way to go.

Linux system table Products include: Motorola E6, A1200, V8, etc. Linux kernel

Android's core system services rely on the Linux 2.6 kernel, such as security, memory management, process management, network protocol stack and driver model. The Linux kernel also serves as a hardware abstraction layer between the hardware and software stacks.

Palm The iconic feature of Palm OS is that it is simple to operate, uses a single thread, and can only run one program at a time. Therefore, Palm OS will never fall into the dilemma of memory overflow due to multiple applications being opened. This is both its strength and its weakness, as many people are not satisfied with being able to handle only one task at a time. Palm's schedule management and note-taking functions are the simplest and most powerful among all operating systems. Palm OS has good compatibility with desktop computers, Office compatibility, and sending and receiving emails.

Multimedia playback is Palm's weak point. Using Palm's own media player program, you can only play MPEG-1 files converted through Palm Desktop, and the effect is not good. For music, you also need to use third-party tools. Only then can you play DRM protected music. Today, when entertainment is the top priority, lagging multimedia performance is one of the reasons for Palm's decline.

Palm used to be the dominant operating system for handheld computers, but now it has lost its glory. Since Sony announced its withdrawal from the international PDA market, Palm's market share has been gradually eroded by Windows Mobile.

BlackBerry "BlackBerry" BlackBerry is the smartphone with the largest market share in the United States. This is due to its manufacturer RIM (Research in Motion) entering the mobile market earlier and developing mobile phones adapted to the U.S. market. Mail system. Everyone knows that the classic design of BlackBerry is its large screen and QWERTY keyboard for easy input, so BlackBerry has always been a giant in mobile email.

Another feature of BlackBerry is that it has a variety of built-in real-time communication software, including BlackBerry Messenger, Google Talk and Yahoo Messenger. However, currently communication can only be done in English, and the software still does not support Chinese fonts. show. Because it is an orthodox business machine, its function in multimedia playback is very weak. Perhaps it should focus on improving this weakness in the future, because the integration of mobile phone functions is the general trend, and people will not be satisfied with just a single function.

BlackBerry’s influence outside the United States is minimal, especially in China. Almost no one uses BlackBerry products, because Chinese people are far less dependent on email than Americans, and Chinese people are pursuing more It's entertaining.

Windows Mobile

The software of Pocket PC Phone and Smartphone is not universal. It is reported that 90% of the codes of PocketPC and Smartphone software are the same, so as long as the two softwares are modified, they can be used on each other's systems.

Both the Smartphone and Pocket PC Phone come with docks that sync with the desktop via ActiveSync - a software program designed to manage the connection between the two devices. . You can configure ActiveSync to synchronize information objects such as email, calendar, appointments, and contacts.

The Windows Mobile operating system can only synchronize with Microsoft Outlook. The recently released ActiveSync 4.1 supports truly seamless synchronization. Windows Mobile has an advantage in managing contacts, and it is easier to search large contact lists. Even if your phone has more than 1,000 contacts, you usually only need to press two or three keys to find what you want. information. With the arrival of Windows Mobile 6.5, Microsoft has added local file support to Word and Excel. In the past, documents had to be converted into a format that can be recognized by handheld devices, but now it is much more convenient. Due to the use of direct-push technology, the E-mail function of Windows Mobile 6.5 has made great progress.

When it comes to multimedia, no other operating system can compare to Windows Mobile. It is the king of multimedia. Every Windows Mobile phone comes pre-installed with Windows Media Player, which supports formats including MP3, WMA, WMV, ASF, and MPG. It can also play AVI files by installing other playback software. Windows Mobile also supports DRM-protected music, TV and movies.

Because of Microsoft's vigorous promotion, Windows Mobile has attracted many allies, and countless third-party software is launched every year. Among various application software, games are something that everyone cannot live without. There are many excellent games under the Windows Mobile platform. As the handheld operating system of software giant Microsoft, Windows Mobile has inherent advantages in terms of compatibility with desktop PCs and Office. Moreover, WM has powerful multimedia performance and can be used for both office and entertainment, making it the most promising operation. One of the systems.

Windows Phone 7 Windows Phone 7 is a smartphone operating system (Windows Phone series) produced and distributed by Microsoft.

When Microsoft released this operating system, its main sales target was the general consumer market, rather than the enterprise market targeted by previous versions.

Microsoft CEO Ballmer released Windows Phone 7

In Windows Phone 7, Microsoft applied a technology called "Metro" to its human-computer interaction interface (User Interface). design language (used in Zune) and integrates other Microsoft-owned software into the operating system to strictly control the specifications of the hardware running it. This announced that the Windows Mobile series has completely withdrawn from the mobile operating system market. The new wp7 completely abandons the operation interface of wm5 and 6x, and the programs are incompatible with each other. It just uses the past version number wm6.5 and then wp7. They are actually two completely different systems. On February 15, 2010, Microsoft CEO Steve Ballmer said at the 2010 Mobile World Congress (MWC2010) in Barcelona, ??"I am honored to introduce to you the Windows Phone series of mobile operating systems. In the market Full of products with the same functions and experiences, I motivated the team to come up with a solution that can bring a new mobile experience," Ballmer said, "The development of mobile phones requires products to truly fit the user's lifestyle, meet social needs and provide various aspects. A seamless experience. The release of the Windows Phone 7 series of mobile operating systems is a turning point in this journey. “The interface appearance of Microsoft Windows Phone 7 is simpler than that of most mobile phone systems. The bright blue icon stands out against a black background. The startup screen has four large square icons, representing mobile phone, contacts, email and text messaging functions. Microsoft calls this setting "Live Tiles", and below this interface is the entrance to the photo album and Xbox Live games. Microsoft has once again emphasized the importance of social functions on mobile phones in the new system. Users can directly update their personal social homepages on Facebook or Windows Live through the contact list and photo album on their mobile phones, and they can also view the information of their friends on social networking sites. page or photo.

Android HTC G1 operating interface Android is an open source mobile phone operating system based on the Linux platform developed by Google. It includes the operating system, user interface, and applications—all the software a mobile phone needs to work—without any of the proprietary barriers that have previously hindered innovation in the mobile industry. Google developed Android in partnership with the Open Handset Alliance, a group of more than 30 technology and wireless leaders including China Mobile, Motorola, Qualcomm, HTC and T-Mobile. By forming deep partnerships with operators, device manufacturers, developers and other interested parties, we hope to form an open ecosystem within the mobile industry by establishing a standardized, open mobile phone software platform . We believe that this move will definitely promote better and faster innovation and provide unpredictable applications and services to mobile users.

As an important part of Google's corporate strategy, Android will further promote the realization of the corporate goal of "providing information to everyone anytime, anywhere". We found that a large number of mobile phone users around the world have never used any Android-based phone. Google's goal is to make (mobile communications) independent of device or even platform. To this end, Android will complement, not replace, Google's long-standing mobile strategy: to develop mobile services that are both useful and engaging by partnering with phone manufacturers and mobile operators around the world. and promote these products.

The establishment of the Open Handset Alliance and the launch of Android are major changes to the status quo, which require a lot of patience and high investment before they can bring initial benefits. However, we believe the potential benefits to mobile users around the world are worth the effort. If you are also a developer and are interested in our ideas, please give us another week before Google can provide the SDK.

If you're a mobile user, just wait a little longer as some of our partners plan to launch phones based on the Android platform in the second half of 2008. If you already have a phone you know and love, log on to the Google Mobile site and make sure you've installed Google Maps for mobile, Gmail, and some other great apps built just for your phone. Google will continue to work hard to make these services better while also adding more attractive features, apps, and services.

In addition to the above advantages, Brew MP will also provide a new business model: the operating system will be provided free of charge with Qualcomm's chipset, and developers, operators and OEM manufacturers will not need to pay any fees to Qualcomm.

Edit this paragraph MTK system MTK is the platform currently used by black mobile phones and some domestic manufacturers. MTK mobile phones are commonly known as copycat phones and occupy a huge share in the low-end mobile phone market.

Advantages of MTK: MTK’s main menu and submenus can be selected using numbers, while Nokia’s submenus require pressing down one by one. . Anyone who uses strokes knows that the Nokia S40 uses Pinyin as the default input method and cannot be changed. The screen brightness and contrast of the Nokia S40 cannot be adjusted. The video playback capability of Nokia S40 is worse than that of MTK platform. The MTK platform has a scheduled power-off timer, but the Nokia S40 does not have a scheduled power-off timer. You can choose to turn it on when the alarm goes off. Nokia currently does not directly support TXT text reading, nor does it support the simultaneous display of MP3 lyrics. These MTKs can do it. MTK can have built-in support for emulator games, and Nokia can use java to support it, but keyboard operation is not so convenient. MTK supports touch functions, which can also be used in games.

Weaknesses of MTK: Poor photo control, there will be a faint red spot problem in the center. There can only be 5 custom ringtones. It is basically impossible to change the theme. Nokia has thousands of themes. MTK's java support is too weak. Nokia's Java is relatively strong. S40V3 supports Java within a maximum size of 1M, but it is enough for daily use. Of course, this is also related to the rush to design Java for Nokia. If someone specifically made Java programs for MTK, everyone would not have to search for general-purpose Java software online all day long.

Personal opinion: In fact, you don’t have to worry too much about domestic mobile phones over-relying on the MTK platform. MediaTek can build the MTK platform. Can’t manufacturers like Spreadtrum and TI see the profits from it? Will you just watch MTK take money? There will be more and more platforms in the future, and the current MP4 players also use solutions from Rockchip and Zhuhai Actions. MTK's Java is a weak point. In the future, new manufacturers will launch platforms that are more cost-effective than MTK in order to seize the MTK market. Therefore, it can be expected that the functions of future mobile phones will become more and more exciting~~ When the platform war starts, it is us consumers who will benefit.
