Most mobile phone software needs to access storage. Is it really necessary?

It should be determined according to the use requirements of the software. The concept of storage permission is too big, and it needs to be divided into different areas and different privacy levels. Give the software the necessary permissions, but different stored information should be distinguished and given different permissions, and the software should report to the owner what information it has accessed.

Many softwares require external storage permission under the guise of caching pictures. In fact, all apps have their own private storage space. If you want an external license, you just want to read your various files, such as photo albums. Don't agree as long as it doesn't affect the use. Do not store sensitive information (ID photo, etc.). ) Where the task is open, if it affects the use, consider the actual situation.

What permissions involve privacy?

I. Contact person

Third, the telephone.

Telephone permission means that the software can make calls. This is easy to understand, so I won't explain it here

Recording means that the software can turn on the microphone to record, which can be done in the background. Therefore, if there are certain risks, we must carefully approve them.

Verb (short for verb) Take photos and albums.

As the name implies, taking photos means that the application can turn on the camera to take photos or take videos. Album permissions refer to the application's access rights to your album, including the rights to modify, delete, add and read photos in the album. Of course, this kind of operation may also happen without the user's knowledge, so grant it carefully.
