Times are constantly evolving, and the technology products people use have changed a bit. Nowadays, almost every young person has a mobile phone, and smart phones are generally sold cheaply. There are some hidden functions on the smartphone, which are not usually used.

You can choose to manage the above software in a category, and close the unused functions in time. If the function is not in use, it will occupy memory, and it may also make the phone stuck. Smartphones will have a function that rotates according to the finger, which is not usually used by anyone.

At this time, you can choose to close it, and it will not affect the memory. <>

Although voice input has always been expanded in life, there are still people who are used to typing or writing. If you don't use it, you can turn off the voice mode in time, which can save a certain amount of power on the phone. Because if the voice input is constantly running in the background, it consumes its own traffic and power functions.

It is necessary to make a suitable setting for the mobile phone according to your personal habits, so as to facilitate your use in daily life. <>

Anyone who has bought an Apple mobile phone knows that there will be an NFC function on the mobile phone, and most of this function may be used for the access control card of the community and the company's access control card. It is generally not used on the mobile phone, and you can choose to unlock it. The steps are very cumbersome, and even if you set it up, it won't be very easy to use.

When it is closed, it can be more convenient to use when it is used, and the access control will not be affected. <>

In general, although smartphones are becoming more and more popular, there are still some people who are not very knowledgeable about mobile phones. The sales staff should help users turn off the functions they don't use in time when selling mobile phones, and explain it clearly to them. If you have any questions, you should ask them face to face to get the answers you want.

In this case, the phone can be well organized, and it will be particularly comfortable to use.

There are many functions on the mobile phone that are not commonly used, such as compass, radio, etc., maybe we don't use it, but there are other people who use it, and the specific scene is divided, in short, there is a reason for installation.

What's the most useless feature on a smartphone?

What are some of the most useless features of smartphones? In fact, there are a lot of applications on mobile phones, although some are not commonly used, but they are still necessary, and in some specific cases, some people need them, maybe we just can't use them, for example, most people don't use the compass function, and now everyone is more commonly used to navigate.

Although the guide is useless for us, in some cases, if someone goes to the deep mountains and old forests to travel, the function of the compass is still relatively powerful, so it is not useless, just to use it in different scenes, and the radio, this is quite useless, now most people will watch TV series, watch movies or listen to songs, and the radio may only be used by older people, this function is also installed on the mobile phone, no one will open it.

Why?

Mainly because the functions of mobile phone software are too powerful, some of the more unpopular functions, compass, radio, etc., will not be too commonly used, mainly because there is now more powerful software than them, such as navigation and various **** software, more powerful than them, more functions, so they are not used by people. In fact, their memory is not large, and the installation does not have much effect.

It can be seen from this that many functions on the mobile phone are not used in our daily life, and this kind of software is often relatively simple, less entertainment, so we don't use them much, and there is a better replacement software, but some software is actually installed, maybe it is necessary, but we have not used it for the time being, the above is mine, I hope it can help you.

I think the most useless thing is the radio function, because 99% of people don't open the app at all.

I think the most useless feature is**; Because there are a lot of ** software that can be used now, most people will not use this feature.

I think it's definitely the radio feature, because the vast majority of people don't use a radio at all, so it's very chicken.
