Do smartphones support expansion 5

Broadly speaking, smartphones have most of the functions of PDAs in addition to the call function of a mobile phone, especially personal information management and browser and e-mail functions based on wireless data communication. Smartphones 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, and many value-added services can be used for it, such as: news, weather, transportation, goods, applications, ******, etc.

Smartphones that integrate 3C (computer, communication, and comsumer) will surely become a new direction for the development of mobile phones in the future.

Not absolutely, smartphones support multiple ** applications, and can generally expand memory.

Nokia's smartphones are all expandable

Not necessarily. Moto MPX200 is smart and does not support insert cards,But basically the smart ones support extensions. It's just a matter of how much or how little is extended. For example, the MPX220 can only support scaling up to 512M....

The vast majority of smart machines support memory expansion.

But on the flip side, a machine that supports extended memory is not necessarily a smart phone.

Apparently impossible. Storage expansion is usually not supported, in order to save space and reduce the size of the phone. You don't want to say how big a memory card is, you look at the difference between the size of the SIM card of the iphone5 and iphone4s, and you have to try to reduce it.

In comparison, the space of a memory card is already huge. What's more, adding a memory card requires adding appropriate control and management chips, and these chips and circuits are huge space overhead.

The development trend of smartphones will be closer and closer to PCs in terms of function, and it is likely that in a few years, there will be mobile phones that can customize hardware configurations like today's desktop computers. Not supporting storage expansion is not a general trend in any way. The storage space requirements for personal computer equipment are almost limitless, so not supporting storage expansion is bound to lose a lot of customers.

In addition, if you don't support expansion, you have to have a built-in large-capacity storage space, but the built-in storage space is more expensive than the external storage space. If you think about it, the 32G iphone4s are hundreds of yuan more expensive than the 16g iphone4s, but if you buy a 32g mobile phone storage card, it is only a few tens of yuan. In general, from the perspective of cost and user needs, not supporting storage expansion will not be the development trend of smartphones.

Flagships are generally not supported, because they want you to buy larger memory and more expensive.
