Min Zheng Tong's QR code shows what it means to open relevant permissions.

You can go to the mobile phone application settings to find the application permissions, and then the app can open the permissions.

Why does the App need to obtain user rights?

For many apps running on mobile phones, some user rights can ensure the normal use of the app. For example, to use the "View Contacts and Friends" function in social software such as WeChat and QQ, users need to be authorized to use the "Read Contacts" permission. When this permission is turned on, you can see who is using the same application in the phone address book. Similarly, map navigation software also needs to obtain the "user positioning" permission to navigate correctly for us.

There are also some permissions that can make mobile apps more convenient and easy to use. For example, you need to enter a verification code to log in to the application. In order to realize the function of "automatically filling in the verification code", App needs to be authorized to open the user right of "reading short messages". It can be said that this permission does not require users to manually fill in the verification code, which improves the convenience of the software to some extent. However, for unknown software, it is not a good habit to open the "Read SMS" permission.

The App of regular software does not need much user authorization. At present, most formal software does not require users to authorize mobile phone rights at will. Let's take the App "Ha _ Bike" as an example. If you want to run "Ha _ Bicycle" normally, you need to apply for three rights: storage rights, user positioning rights and reading equipment information. If you want to drive a bicycle in the software, you need to turn on the camera and turn on Bluetooth.
