Saipan system（Symbian system）It is an operating system designed by Symbian for mobile phones. Its predecessor is the EP (Electronic Piece of Cheese) operating system of British Baoyiang Company.
In Symbian's development stage, there are three branches: Crystal, Pearl and Quarz.The first two are mainly aimed at the communicator market, and also appear most frequently on mobile phones. They areSmartphone operating systemThe main force of.Section 1 Based onSymbian systemOur mobile phone was launched in 2000Ericsson mobile phone。However, the one that really matures and attracts people's attention is the one that was listed in 2001NOKIA9210, which adopts the system of Crystal branch.And in 2002NOKIA7650 and 3650 are Symbian Pearl models, of which 7650 is the first model based on2.5GThey are all Symbian's version 6.0 smartphone products.Sony EricssonThe launched model also uses Symbian's Pearl branch. The version has grown to 7.0, which is designed for3G networkDeveloped by, it can be said to represent the most powerful mobile phone operating system at that time.In addition, Symbian has supported external storage devices since version 6.0, such as MMC,CF cardThis gives full play to its powerful expansion ability to store more software and various large capacityMultimedia filesIt is possible.[1]

In terms of model, there is only one series, namely 9 series.Symbian OS Crystal platform is used.It represents the strongest technology of NOKIA, and each generation is at that timeNOKIAA collection of all the most advanced technologies.The biggest feature is that it is like a pencil box. There is a standard mobile phone operation interface on the outside. Inside, there is a 640X200 large screen with fourFunction keys, NShortcut keyAnd a full QWERTY keyboard.The net weight is usually about 200g, but it is powerful.It can be said to be the best business phone.NOKIA's own senior managers basically use this stuff.Typical examples are 9110/9210/9300/9500.

To promote and improveUIQSymbian founded UIQ Technolgy, a company that aims to develop and promote UIQ.At present, it seems thatUIQNo NokiaSeries 60The system is popular because it is based onUIQThere are few mobile phone products on the platform;However, with the emergence of UIQ 3.0, this situation will change dramatically, and more manufacturers will choose to configure UIQ platform for their products.
In 2009, various companies withdrew from Saipan platform, and UIQ company also went bankrupt in 2009.According to the decision of Symbian Foundation, UIQ user platform will stop development, while Nokia'sS60It will become the first choice of Symbian Foundation's user interface. At the same time, UIQ will contribute all its code and other assets to the Foundation.

Symbian operating system once competed with Windows Mobile, Palm OS, webOS, Linux, Android, iOS, etc,Windows Mobile、Palm OS、webOSHas lost market share, andiOSandAndroidThey took advantage of the opportunity to occupy the vast majority of the market share.Symbian has no choice but to compete with the embedded operating system used in low-grade mobile phones, which tends to be developed by various manufacturers.Compared with the embedded operating system, Symbian's advantage lies in its standardization -programThe runtime can call each other's shared libraries, as well as the addition architecture (that is, software can be installed).These allow mobile phones with more complex functions to be developed at a faster speed, which sometimes offsets some of the delaysC++Difficulty.
Symbian and Open Operating SystemLinux, and closedWindows MobileBy comparison, its advantages are more controversial.Mobile phone manufacturers and network operators prefer Symbian's customization flexibility to deny itWindows CE。Although these customization flexibility make it more difficult to integrate Symbian mobile phones.Symbian's limitations on hardware architecture and cumbersome application signature authorization also make it unable to compete with the new generation of operating systems (such as Android).
Due to poor support for emerging social networks and web 2.0 content, Symbian's market share in smartphones is shrinking.Its market share decreased year by year from 72.8% in the third quarter of 2006 to 37.6% in the third quarter of 2010.Since the end of 2009, major manufacturers including Motorola, Samsung Electronics, LG, Sony Ericsson and others have announced to stop developing Symbian platform and invest insteadAndroidDomain.At the beginning of 2011, Nokia announced the establishment of a strategic alliance with MicrosoftWindows PhoneAs a result, Saipan, which has been operating for many years, is abandoned, and its delisting has become a foregone conclusion.

Nokia announced to stop developing Symbian system and manufacturing Symbian mobile phones
According to foreign websites,NOKIAIt is pointed out in the released company financial report thatNokia 808Pure View will be the company's last mobile phone based on Symbian system, which also marks the official announcement of the death of Symbian system by Nokia.[11]
Saipan system
Nokia said: "In 2012, weWindows PhoneDuring the transition, Symbian system mobile phones have been sold.However, the 808 PureView released in the middle of last year will be our last Symbian phone. "
It has long been rumored in the scientific and technological circles that,PureViewIt is the first work of Nokia Symbian system.At the same time, the industry is also crazyPureViewImaging technology will transition toLumiamobile phone.
Analyzing why to abandonSymbian systemThe German Financial Times said that code aging was the main reason.Symbian is based on the Epoc OS developed in the 1990s.At present, Symbian has 30 million lines of system code, nearlyWindows XPLevel.Experts said that the new core functions are difficult to implement on Symbian.NOKIAIn responseiPhoneOne of the reasons is that Symbian transformation is time-consuming and laborious.
NOKIAThe financial report released today shows that 2.2 million Symbian mobile phones were sold in the fourth fiscal quarter of 2012, onlyLumiaHalf of mobile phonesNokia SmartphoneThe proportion of total shipments (15.9 million) is less than 14%.
Before the rise of the Apple platform, Symbian was the leader of the smartphone platform.However, Symbian mobile phones account for only 2.6% of the market share of all mobile phone shipments,Android72%.Part of the reason for this gap is the sluggish demand.According to the data, the sales of Symbian mobile phones in Greater China fell particularly seriously, with a year-on-year decrease of 69% in net sales.On the other handNOKIAThe in-depth development of Symbian mobile phones has been abandoned, and the R&D expenses and marketing expenses have been greatly reduced.
Although everyone knows that there will be such a day sooner or later, when it really comes, everyone will still sigh.
The old Symbian can no longer run the new system, and finally fell today.
On January 24, 2013,NOKIAIt was confirmed in the financial report of the fourth quarter of 2012 that 808 PureView was the last Symbian mobile phone, and Symbian had died.With the good memory of a generation of players, a glorious era has come to an end.
In Finland, there are still some customers using Symbian mobile phones, and the software developed by a third party still needs to be upgraded.The release of Symbian software requires a signature.It seems that the certificate required for signature can only be renewed abroad, while companies that can issue certificates in China are said to not issue certificates until October 2013.
Although Saipan has diedoperating systemThey all apply totouch screenOn mobile phones, when Symbian was the leader of the operating system, keyboard phones were popular, and Symbian had a very prominent effect on keyboard phones, but it was not suitable for touch screen phones, which should be experienced by many users when using the touch screen phones of Symbian system.However, the most powerfuloperating systemIt is still Saipan.
