S40 or S60 refers to the upper platform of Nokia mobile phones. The S60 are all smartphones, and the underlying operating system used is Symbian.

Nokia’s 128*128 screens are all S40 1.0. And 128*160 is S40 2.0

In addition, among S40, 3100 supports JAVA MIDP 1.0, so it supports JAVA up to 64KB; 6230 supports JAVA MIDP 2.0, so it supports JAVA up to 128KB

40 and 60, including 90, and the previous 30, are all for operating systems different from Nokia

40 is a mobile operating system developed by Nokia itself. It supports mid- to low-end customers. The development of kJAVA has low processor efficiency, low memory, and a screen size of 128*128

60. It is based on the symbian operating system, which is the previous epoc. Its processor is arm9 and the processing efficiency is very high. High, the memory is quite large, the screen size is 208*176 and supports the development of kJAVA and C

90, it is a handheld device, and it is also a symbian operating system but has powerful functions, which is equivalent to a PDA

In fact, technically speaking, the difference between S40 and S60 lies in the system platform, just like WIN98 and WIN2000. However, mobile phones are not like PCs. The screen size is indeed a barrier, so it is not easy for the platform to be backward compatible, but Some games also have different versions

Of course, the difference between the S40 and the S60 is not only the screen, but also the performance gap. Generally speaking, games developed on the S60 The quality is much higher than that of S40, but unfortunately, S60 is much more expensive than S40

Nokia 40 series refers to: 7600, 7200, 7250, 7210, 6100, 6220, 6230, 6610, 6650, 6820, 6800, 6810, 3100, 3200, 3300, 5100.

Nokia 60 series refers to: 3650, 3660, 6600, 7650, N-Gage.

40 small screen ~ 60 large screen ~ 80 super large screen

In the United States, there is a book about cowboy culture with an outstanding title called "Those who don't have jeans, please raise your hands." Perhaps in the near future, we will also write such a book, called "Raise your hands if you don't have a Symbia" phone. Despite facing fierce competition from rivals, Motorola still has a market share of up to 80%. The company is still reluctant to give up after withdrawing from Symban's shares.

But when introducing the history of Symban, we must mention Psion (Sion) and its EPOC operating system.

Svmbian was developed from them. Psion, a company founded in 1980, is mainly dedicated to the development and research of digital products

It is said to have invented the world's first electronic organizer (the prototype of a punch computer). . It pioneered the handheld computer market. EPOC is an operating system launched by Psion Software.

Specially used for mobile communication devices, including handheld computers, EPOC is an open operating system

And since the beginning, EPOC has added wireless communication and an additional application system, so it has inherent advantages compared with other operating systems in wireless communication. At the same time, it is the same as Microsoft's windows

cE. EPoc is also a 32-bit operating system.

Real-time and multi-tasking. Multi-threading, low power consumption. Features include low memory usage.

In June 1998, Psion joined forces with Nokia

Ericsson and Motorola to establish Symbian. The company inherited the license of Psion's EPOC operating system software and is committed to Provide a secure and reliable operating system and a complete software and communicator platform for mobile information devices. As an open platform, Symbian exposes 80% of its source code so that anyone can develop software for Symbian-supported mobile devices. p>

Symbian company shareholders and share distribution chart

Symbian company is also heavily involved in the development of WAP, WireJess Java and Bluetooth. Therefore, it is closely related to Microsoft's Windows

Mobile operating system. Compared with Symbian, it has unique advantages in communication and is designed to ensure that user data will not be lost regardless of power outage.

At the same time, the system is a so-called micro-kernel operating system. "Microkernel" means that only a small part of the operating system runs at the highest priority, and other functions are provided in the form of client-server.

The current Symbian because of Panasonic, Siemens and Samsung has joined companies jointly controlled by Psion, Nokia, Sony Ericsson, Motorola, Panasonic, Siemens and Samsung. In the first quarter of 2004, LG, Arima and Lenovo became the latest companies to obtain Symbian licensing agreements. Mobile phone manufacturers. This brings the total number of authorized manufacturers to 1

including almost all major mobile phone manufacturers in the world. In 2000. Ericsson R380 was successfully launched.

In 2001, Nokia released the famous Series60 software platform for the first time.

In the same year, the world's first mobile phone based on the open Symbian operating system, the Nokia 9210 personal communicator, came out. . 2002. Japan's NTT

DoCoMo released the first 3G mobile phone FOMA F2051 using the Symbian operating system. In the same year, Nokia launched the first mobile phone based on the Series60 and Symbian operating systems. 2.5G mobile phone - 7650. In 2003, Nokia launched the Senries60 mobile phone 6600 using the Symbian7.0s operating system. In 2004, the first 3G mobile phone 6630 with the Symbian8.0a operating system came out on April 27, 2005. Japan

The first Symbian 9.1 operating system mobile phone Nokia N91 was released.

In the meantime, Motorola sold all its shares in Symbian in 2003 and developed smartphones with Linux operating system. Symbian CEO Dayid

Lavin even naively believed that Motorola's PCS department must be under pressure from the Chinese government, because the latter hopes to use the Linux operating system in smart phones.

Symbian's parent company has three products, namely Pestl (Pearl). Quartz (quartz) and Crystal

(crystal) are used in smartphones, pen input communicators and keyboard input communicators. The differences between different series mainly lie in the user interface

(for example: handwriting or keyboard input) and screen size. Among the three series, Quartz and Crysta are both called "communicators"

Only Pearl is a "smartphone". According to the official description. Quartz uses handwriting input, and the screen pixels are 320 x 240.

CrystaI is a terminal that supports full keyboard operation.

Use half VGA color monitor (640 x

200 pixels). Nokia 9210 is the representative of Crysta. As for the familiar Nokia Seirs60 mobile phones and Sony Ericsson P800, P900 and P910, they are the "smartphones" of the PearI series. However, due to Quartz's existence in name only

Symblan's product classification has been changed to mobile phones with numeric keyboards (including the Series 60 series and Fujitsu's independently developed application interfaces, etc.)

Mobile phones with touch screens (Mainly mobile phones that use the UIO interface, such as Sony Ericsson P910 and Motorola Al000, etc.) The last type is mobile phones that use a complete keyboard and a large color screen, such as the Nokia 9500.

Through software licensing, Symbian can get $5-$7.25 from each phone sold that uses its software. After several years of hard work. Symbian's market share has been greatly improved with the sales of Nokia Series60 products, and it currently has about 80% of the smartphone market share. Symbian,

a "small company" located in the UK, dominates the promising smartphone market.

Symbian operating system authorized manufacturer map

In many cases, people who are not familiar with the Symbian system think that Series60 and 80 are different Symbian operating system versions. So there were some jokes like "Series60 operating system" and even "Symian

80 operating system".

In fact, the symbian operating system is a mobile operating system developed by sYmbian Company. It is an operating system independent of mobile phone hardware, so it can be installed on any mobile phone that meets basic system resource requirements. However, mobile phone manufacturers do not want the interface and functions of their mobile phones to be the same as those of other manufacturers.

So some local modifications are generally made based on the symbian operating system. As a result, names such as sso and s80 appeared. They are not operating systems. It is a development platform based on the operating system. Through these development platforms, mobile phone manufacturers can quickly develop mobile phones with unique interfaces and advanced functions. We used to call these development platforms "user interface", but now, the capabilities of the development platforms represented by s60 have far exceeded the original "user interface" goal. Go deep into the customization of the internal functions of the mobile phone. Therefore, we now call it a "development platform".

If you include mobile phone manufacturers such as Japan's Fujitsu that use the Symbian operating system, under the current circumstances, the development platform of the Symbian system should have self-developed interfaces such as UIO, Series60, Series80, and Fujitsu.

S60 mobile phones account for the majority of products using the Symbian operating system.

Among them, the ulo user interface is mainly used by Sony Ericsson, Motorola and some Taiwanese brands. Its main features are support for handwriting and 208 x

320 pixel touch screen, using two-hand operation. . The Series 8O developed by Nokia has a so-called half OVGA screen and full keyboard input, representing the models 9500 and 9300. In contrast, the Series 60 designed for numeric keyboard phones can no longer use a Simple user interface interface to express. Based on its open architecture and external authorization, according to Nokia's official statement, "Series

60 is a feature-rich smartphone software platform with advanced data processing capabilities." The main features of this software platform Developed on the basis of the

Symbian operating system, it not only has a complete user interface that can adapt to various needs, but also has a set of rich and colorful applications. At the same time, this is a platform with flexible design. It not only has a set of common user interface components and development tools. It is convenient for developers to implement some new functional applications.

Moreover, Series

60 is specially optimized for the Symbian operating system. And it is also a source code product. Mobile phone manufacturers licensed by Nokia can port it and integrate it into their own hardware designs.

Nokia Series 60 uses the Symbian operating system and PreaI platform, which is positioned for one-handed operation

And most of them use AMR9-based processors and TI communication modules. The screen resolution of the mobile phone in the reference design is 176 x

208 pixels, and it has five direction keys and two function keys. The menu of the mobile phone is arranged in a nine-square grid. Supports MIDP Java and SIS extension packages written in C. Companies currently licensed for Series 60 include Siemens, Panasonic, Sendo and Samsung.

There are currently three main versions of Series 60, namely the first edition (Developer Platform V1.0) and 2ndEdition and

3rdEdition (second and third editions)

The first version of Series 60 includes the following features: Using

Symbian6.1 operating system. Java technology supports (MIDP) 1.O, (CLDC) 1.0 and (JSR-1.20).

(JSR-135) and other application programming interfaces, equipped with XHTML/

WML browsing and supporting MMS multimedia text message service, supporting personal information management: calendar, phone book, photo album, directory . File management applications that can be synchronized with PC, and data connections support USB, Bluetooth, IrDA protocols and GRPS, etc. Mainly supported mobile phones include Nokia 7650, 3650 and Siemens SXl.

Series 60 version 2 was originally released in 2003. The first mobile phone to support this version was the Nomiya 6600 mobile phone. The main feature is the unified messaging center (unifien Messaing

Center, MMS, SMS, Email). Various OMA instant messaging and presence applications, a complete mobile Internet browser (HTML 4.0 XHTML MP, amp; WAP CSS), 3GPP compatible streaming client (RealOne Player), Java MIDP

2.O environment, application manager, OMA digital rights management (forwarding lock), SyncML data synchronization and device management,

OMA client configuration, media gallery, video recording Mobile applications, image viewers, connection managers that support multiple PDP scenarios, mobile wallets, and a variety of personal information management applications, etc.

And through expansion, Series 60 Second Edition has been added to three Feature Packs, adding some new features while maintaining past compatibility. These new Feature

Packs also illustrate the flexible design and scalability of Series 60. This version uses the Symbian 7.0s operating system, and the user interface supports multiple screen resolutions (176 x

208, 240 x 320 (OVGA) and 352 x 416 pixels).

Among them, Series 60 Feature

Packs1 mainly adds support for EDGE technology, supports built-in megapixel cameras with stronger shooting capabilities, and enhances the application capabilities of Java technology. , improving the application level of multimedia, especially increasing the application of MP3 and AAC format music. In addition, the browser and information processing have also been improved. Mobile phones using this version mainly include Nokia 7610, 6260, Panasonic X700 and the latest Nokia 3230.

Featrue Packs2, the second edition of Series 60, uses the more advanced Symbian 8.0a operating system. The built-in OpenGL

ES engine supports 3D technology, adds support for WCDMA networks and has been enhanced in Java support, information email, and multimedia applications. In addition, the Feature

Packs2 also prominently adds support for Japanese and Thai. So it’s no surprise when the 6630 and 6680 make their way to Japan.

Series 6O Feature Packs3 supports SVG’s scalable user interface architecture. Supports high-resolution string display 176 x 208, 240 x 320, 352 x

416 pixels; the platform supports traditional keyboard input, rich email content (HTML, MS Office, etc.). For example, MS can be viewed in the attachment of the email.

Office documents); user interface that supports wireless LAN, etc. The N70 and N90 in Nokia's latest N Series series are models using Series 60 Feature

Packs3.

The third edition of Series 60 released by Nokia during this year's 3GSM World Congress mainly emphasized multimedia and enterprise functions among the added functions. This version is equipped with the new Symbien

9.1 operating system, but still retains the features and functions of the previous version. Includes multiple wireless formats, an extensive application suite, a scalable user interface and high-resolution support as major improvements. New features in Series 60 version 3 include enhanced support for different hardware configurations, including single-chip and dual-chip hardware architectures and improved performance. In terms of multimedia functions, the third version of Series60 will provide a new music player. The new music player will provide seamless and easy-to-operate music downloads with personalized themes and backgrounds. At the same time, Open Mobile Alliance Digital Rights Management (DRM) version 2.0 is also adopted to provide enhanced functions for rich media content, and at the same time realize the protection of high-security content. In addition, support for the USB Mass Storage protocol allows Nokia Smartphones to be used as ordinary USB storage for the first time. Its purpose is also to realize music transmission from PC to mobile phone in a more comprehensive way.

In terms of enterprise applications, the third version of Series

Series 60 mainly enhances the security of business data. For example, the security of calendar, synchronization and phone management has been improved compared to the past. The mobile phone currently using this version is the 2-megapixel mobile phone N91 with 4GB storage capacity just released by Nokia. In fact, as far as the Series

60 software platform is concerned, its advantages and disadvantages are the same as those of the Symbisn operating system itself. Disadvantages are inextricably linked. From the advantage point of view, Series60 is based on the widely authorized Symbian

operating system, has a considerable number of development partners, and provides numerous Java

APls, c programming Development Kit. At the same time, many years of mature mobile phone platform research and development experience, coupled with the completely open source code 0 and the stability of the Symbian operating system, make it easier for manufacturers using the Series60 platform to quickly replicate production. At the same time, because its embedded Symbian operating system has better support for mobile communication protocols, it also has unique advantages in terms of users compared with other operating systems. Even in terms of cooperation with operators, it is unmatched by other platforms.
