What exactly is S4's intelligent system? Explain it?
just as the Windows system is divided into multiple versions, the Series platform is also divided into S4 (JAVA platform based on mass market), S6 (based on mainstream smart terminals), S8 (based on high-end business and mobile office applications) and S9 (based on forward-looking hand-held touch control mode) according to product positioning. However, different from Windows system, each major category of Series platform adopts different technical specifications. Except for S9 system, which has only one 771, the other S4, S6 and S8 have all undergone the upgrade of operating system version. Among them, S4 system platform has the widest user base, and its latest version prototype has been first reflected in 627. After getting the engineering prototype of 627 first and launching a detailed evaluation with the attitude of the first launch in China, many netizens responded enthusiastically to the new version of S4. Therefore, the IT World Mobile Channel combines the official and related materials to present an exploratory special report on Series4, which does not seek everything, but only seeks to make you more appropriately appreciate the essence of S4 and make a proactive experience of the third edition of S4, and then start a wider discussion.
Nokia's definition of S4 platform is a Java mobile phone platform for mass market, which has experienced three versions of development. Compared with S6, S8 and S9, S4 is built on Nokia's own closed operating system platform. Because Symbian OS is not used at the bottom, S4 platform cannot support C++ program development, and the expansibility of the operating system is limited to the application of JAVA programs.
after defining the definition of S4, we will continue to study the change of S4 system version. At first, Nokia 712, 661, 31 and other models can only use the main menu style of large icons, and the screen configuration is mostly 496-color STN display with 128×128 pixel resolution, and then it gradually develops to support nine-grid menus, such as 725, 725i and 32. The 72 with 65536 color TFT color screen and the 76 with 128×16 pixel resolution can be regarded as the last works of the first edition of S4, and it can be analyzed from the screen configuration that the products of this period are ready to transition to the second edition of S4. In addition, judging from the JAVA version supported by the product, S4 models are all JAVA applications that only support MIDP (Mobile Information Device Description) 1. and CLDC (Limited Connection Device Configuration) 1., which has a 64KB limit on JAVA programs. As for the browser version supported by S4 model, most of them are WAP 1.1, and a few models have reached WAP 1.2.1 or WAP 2..
in other respects, the models in the first edition of S4 only have midi music playback, and only the exceptional models such as 33 and 76 support MP3 playback. Except for the 33 which supports MMC card extension, the other models in the first edition of S4 do not support external memory cards.
The first version of S4 mobile phone is best-selling with models such as 661, 61, 31 and 72. After extensively absorbing user feedback to improve and enhance, Nokia began to launch the second version of S4 products in the second half of 24. The main feature of S4 second edition mobile phones, represented by 322, 623 and 727, is that the screen configuration is generally upgraded to 65536 color level, while the straight model is still maintained at 128×128 pixels, while the folding model is 128×16 pixels, which adds good support for theme mode. The theme elements with extension *.nth can change wallpaper, screensaver, ringtone, color matching and so on at one time. At the same time, all S4 second edition models support JAVA MIDP2. and CLDC1.1 versions, and newly provide JAVA Bluetooth interface specification (JSR-82), wireless information interface specification (JSR-12) and mobile media interface specification (JSR-135). The WAP browser of S4 model in the second edition was upgraded to version 2., which increased the support for XHTML action description and WML browsing via wireless scene TCP/IP(wTCP/IP), and strengthened the entertainment function and network application.
Strengthening multimedia function is also the progress of S4 second edition. Many high-end products already support MP3 and AAC music playback, but the sound quality is mediocre. In addition, there are still few models supporting external memory cards, and only support MMC card expansion, which has certain disadvantages in versatility and data transmission speed.
In the two high-end models of S4 2nd Edition recently launched by Nokia, 623i and 88 with 28×28 pixel resolution appeared, in which the latter also increased the color coefficient of the screen to 26, colors, which greatly improved the screen resolution without changing the visual area of the screen, and achieved a more delicate display effect. The 88 with 26, colors has reached the strongest display effect in the current S4 2nd Edition mobile phone. Many S4 second edition mobile phones have the bottleneck that JAVA programs can't exceed 128KB, but 623i breaks through this limitation and supports 512KB JAVA programs at most. It can be seen from the improvement of screen resolution and the bottleneck capacity of supporting JAVA programs that the second edition of S4 is brewing a new round of reform.
The success of Nokia S4 products in the market is obvious to all, so it is imperative to increase R&D investment in this field. At the Nokia Connection 25 conference held simultaneously in Helsinki, Finland and Singapore, Nokia officially announced the launch of a new version of Series4 platform for application development. The latest S4 version 3 will bring new opportunities for developers and operators to enter a wider consumer market. The first batch of 627, 628 and 6265, which will be listed in the fourth quarter of this year and adopt the third edition of S4, have attracted much attention.
the third edition of Seires4 platform is a complete architecture including hardware, software and application programming interface, which provides enhanced user interface and supports rich multimedia applications, further strengthens the game and entertainment applications, adds a 3D image engine, and provides better support for JAVA. The common problems of the first two versions of S4, such as small screen and low resolution, have also been significantly improved. While equipped with a large screen, the resolution has been raised to the level of QVGA(24×32), and the newly designed man-machine interface can better reflect Nokia's corporate philosophy of "people-oriented technology".
as the first S4 model, the 627 is equipped with a 26,-color TFT display screen with a QVGA resolution of 24×32 pixels. The perfect combination of the two brings a shocking display effect. In addition to upgrading the hardware configuration of the screen, Nokia has also designed a brand-new man-machine interface. The vector icon of the zodiac has a more beautiful visual effect, which strengthens the theme mode supported since the second edition of S4, and supports dynamic desktop layout, which is more in line with users' requirements for DIY desktop style. The shortcut icon menu similar to Windows Mobile system that appears on the standby interface can be defined by users themselves, which effectively improves the operation efficiency. Excellent display effect and more user-friendly operation interface have laid a solid foundation for the excellent performance of the new S4 mobile phone in multimedia.
It is an indisputable fact that the old version of S4 mobile phone is not satisfactory in music performance. This time, Nokia has also strengthened this important detail. Taking 627 as an example, the stereo sound effect of dual speakers is clear and clear, and the newly added stereo enhancement function brings a virtual surround sound stage. Powerful musical performance enables MP3 and AAC music to be played back more thoroughly, and the effect of playing video files also gives people a refreshing feeling. According to the data, the third edition of Series4 supports streaming audio in adaptive multi-rate wideband (AMR-WB) format and Advanced Audio Coding (AAC) format, and also supports video in H.263 format.
the new version of S4 platform continues to be well compatible with JAVA MIDP2. and CLDC1.1, and some new Java specification requests (JSR) have been implemented. the extended API includes interactive three-dimensional graphics (JSR-184) and file connection and information management functions (JSR-75). First of all, let's talk about improving the file connection specification. The third version of S4 model has improved its Bluetooth transmission function. Users can actively search for data Bluetooth devices through "New Devices" under the menu of "Paired Devices" and support some Java APIs(JSR 82) for Bluetooth. The playback function of Bluetooth headset appearing in 623i can also be found in 627. When it is used with the upcoming Nokia Stereo Bluetooth headset HS-12W, players can completely get rid of the cable constraints and enjoy the fun of portable music.
the upgrade of information management function is mainly manifested in that the new version of S4 mobile phone will support OMA MMS v1.2, and two pictures can be placed on the same page, and the maximum capacity of MMS has reached 3K. However, at present, domestic network operators have set a capacity limit of 1K for MMS, so we can't enjoy the fun brought by this upgrade for the time being. Surprisingly, the 627 uses the Mini SD card with higher versatility and data transmission speed as an external memory card. I hope this improvement can be unified in all S4 third edition models.
"Interactive 3D graphics will provide richer games, messaging, customized user interface and product visual effects, as well as more advanced functions", citing the speech of Ms. Epting, global vice president of Nokia Forum. The 3D image engine newly added in the third edition of S4 brings richer entertainment applications, especially in games. With the support of new technology, classic games like snake can also play new flavors. With the popularity of models, it is believed that the corresponding three-dimensional games will become more and more abundant, and the pleasure brought by mobile games will continue to increase.
Sony Ericsson K75c and W8c sounded the horn of 2-megapixel shooting, and Nokia took the lead in responding with 2-megapixel Nseries. Then the emergence of 627 and other products also marked that Nokia quickly popularized the term 2-megapixel. Changing the disadvantages of previous S4 models, a new generation of S4 products, represented by 627, began to support full-screen framing, and at the same time, the shooting function was also enriched a lot. In the past, S4 models only recorded photos and evolved into photos with performance value on 627. Although the effective pixel of the camera is not the criterion for judging the third edition of S4, we believe that supporting full-screen framing and enhancing shooting function settings will be the * * * characteristics of the third edition S4 model.
The third edition of p>Series4 platform is an important part of Nokia's platform strategy to support mobile application development. The new series of products based on high performance will bring more multimedia applications and services. By providing a consistent technical platform among different mobile phone models, Nokia's developer platform approach can maximize the scale of business opportunities for developers, while minimizing the possibility of porting applications and services between different mobile phones, effectively avoiding targeted R&D investment for different mobile phones. Developers can build core functions based on platform technology, and optimize application programs according to the technical expansion of user interface and specific target devices, such as: creating various themes to realize personalized customization of user interface appearance and sound effects; Provide enhanced musical experience and promote the application of mobile multimedia.
compared with the first two versions of Series 4, the third version of S4 mobile phone will appear in a high-profile manner with top-level sound and sound configuration and powerful multimedia functions, which makes Nokia's humanistic concept always embodied in its intuitive surface performance, and undoubtedly makes Nokia mobile phones "pay equal attention to wisdom and beauty" by inheriting the fine tradition. From the general direction of mobile phone development, the progress of the third edition of S4 is worthy of recognition. The software platform with higher compatibility and wider openness will provide more opportunities for relevant developers, and the S4 system will be continuously improved under the complementary conditions. From the consumer's point of view, the model with the new version S4 will bring users better audio and video enjoyment, and the increase of 3D image engine can also greatly enhance the player's game pleasure. What we can expect here is that the third edition of S4 will once again lead the mainstream of mobile phone development and provide operators with more exciting and humanized mobile life enjoyment.
