Do we usually use non-smart phones?

What is a smart phone? Generally speaking, it is a simple formula of "1+1=" PDA+mobile phone = smart phone ". Broadly speaking, smart phone not only has the function of talking on mobile phone, but also has most functions of PDA, especially personal information management based on wireless data communication, browser and email functions. Smart phones provide users with enough screen size and bandwidth, which is not only convenient to carry around, but also provides a broad stage for software operation and content services. Many value-added services can be introduced in this respect, such as: stock, news, weather, transportation, goods, application download, music and picture download, etc. 3C (computer, communication, consumption) smart phone will surely become the new direction of mobile phone development in the future.

What about the smart phone? The popular saying is "Wenquxing+mobile phone = smart phone". A comparison shows that there is a big difference between PDA and Wenxing. In terms of functional application, PDA has its own obvious advantages.

In fact, the easiest thing to distinguish between smart phones and smart phones is whether there is an operating system. Let's take a look at several prerequisites for becoming a smart phone:

1, which has all the functions of an ordinary mobile phone, and can be used for normal mobile phone applications such as calling and texting.

2. Have wireless Internet access capability, that is, support GPRS under GSM network or CDMA 1X or 3G network under CDMA network.

3. It has the functions of PDA, including PIM (Personal Information Management), schedule, task arrangement, multimedia application and web browsing.

4. Have an open operating system. On this operating system platform, more applications can be installed, so that the functions of smart phones can be expanded infinitely.

Since only mobile phones with operating systems can be called smart phones, what are the types of operating systems? Since the birth of smart phone is related to PDA, its operating system will certainly be related to PDA. Symbian and Windows CE, Palm and Linux are still the four camps. However, unlike Palm and Windows CE competing for hegemony on PDA operating system, Symbian has taken the lead in smartphone operating system, and Sony Ericsson, Nokia, Motorola and Panasonic basically adopted Symbian-based operating system.

Symbian:Symbian is very similar to the combination of Windows and Linux. It has a good interface, adopts the technology of separating the kernel from the interface, has low hardware requirements, and supports C++, VB and J2ME. Poor compatibility. Representative model: Nokia 6600 Sony Ericsson P908 Siemens SX 1

WINDOWS CE: Due to the powerful strength of Microsoft, Windows CE has many inherent advantages, such as powerful built-in software, such as Word, Excel, IE, MSN Messenger, Outlook, Media Play and so on. It is difficult for similar software on other systems to be so perfectly unified. Due to the extremely high hardware requirements and high price, the power consumption is still very large and the system stability is poor. Representative model: dopod smart phone series.

Palm: This system doesn't require much hardware, so it can be well controlled in price and consumes little power. PALM appeared earlier, but there are still many imperfections in its application in mobile phones. Like the other two systems, PALM is weak. Representative model: Samsung SGH-i500Treo 600.

Linux:Linux has many advantages, such as open source code, low cost of software licensing, rich human resources for application development, and convenient development of personal and industrial applications. Starting too late, there is no solid foundation. Representative models: Motorola A760, Samsung i5 19.

Besides these four operating systems, have you heard of other operating systems such as S60 and S70? What are these? Actually, these are all branches of Symbian. Why do you say that? It turns out that Symbian OS is just the kernel of an operating system, and the interface can be developed by various manufacturers themselves. The interfaces of 92 10 and 3650 are different, and P908 and 6600 are different. 6600 uses 60 series interface, and P908 uses UIQ interface, which also leads to the program can not be universal because of subtle differences. Even Symbian OS 6.0 of 92 10 and 6. 1 of 3650 are mostly incompatible because of interface problems. I think we need to wait a few days to solve this problem. In different interfaces, there are different advantages and disadvantages. 60 series is easy to operate, and it is easy to switch off tasks, while UIQ interface can support handwriting operation and has more functions, but it is more troublesome to switch off tasks. Okay, let's get down to business. Let's talk about how to get out of the misunderstanding of smart phones and smart phone purchases.

Since we want to get out of this misunderstanding, we must first know its true face.

Myth 1: A mobile phone that can input by hand.

Many friends think that mobile phones that can be input by hand are generally smart phones. In fact, there is no direct causal relationship between the two. For example, Duoyi of TCL E859 and E757 has handwriting function. Because there is no operating system, we define them as smart phones. On the contrary, dopod 535, as a smart phone, does not support handwriting function, so we will not regard it as a smart phone! So there is no direct causal relationship between the two.

Myth 2: Built-in feature-rich mobile phone

Is a multi-functional mobile phone a smart phone? The answer is no, for example, the T868 of CECT has many built-in functions and also integrates PIM functions. Do we also regard it as a smart phone? Give a very appropriate example to illustrate this problem. Before 386 and 486 computers were sold in Chinese mainland, a kind of "Little Overlord" learning machine with similar computer functions appeared in the market. I don't know if you have heard of this product, but I have one at home. Because there was little software involved in the computer at that time, the learning software built in the learning machine was basically the same as the computer software, so the difference between them was not very big. However, with the development of computer technology, more and more applications and game software have been developed, and the market of learning machines has gradually shrunk. It is very difficult for the learning machine to keep up with the upgrade of computer software and hardware.

Similarly, although many smartphone manufacturers can provide online software upgrades and other functions, users have few choices. Because software update requires mobile phone manufacturers to spend more energy, in today's mobile phone market, the time to market of new products is the most concerned issue for mobile phone manufacturers.

Conversely, the functions of smart phones must be very rich. Why? Because its own operating system plays a big role in it. Smartphones corresponding to Symbian and Windows CE, Palm and Linux will find quite a lot of free resources on the Internet. What a pleasant thing it is!

Seeing this, I believe everyone has a spectrum of how to distinguish between smart phones and smart phones! But from the price point of view, the price of smart phones is significantly higher than that of smart phones. After all, it is "a penny for a penny." I would like to remind readers who want to buy this type of mobile phone that before buying a mobile phone, they need to think clearly about what type of mobile phone they need, and they must ask clearly when buying, so as not to be confused by what is on the surface of the mobile phone.
