Why do you ask for access to your address book, photo album, camera, etc. No matter what you log on to now.

One is to get the contacts in your address book, on the other hand, you can match them in his own system to find and mine your friends. Then you are prompted in the APP that you may have the following friends. I suggest you add friends with your address book friends in the APP. So you can pass

Your friend is watching, your friend is watching.

This function promotes your own content. On the other hand, through your contact's mobile phone number, you can push the download method of your own APP to him through advertising SMS to tap potential users.

In today's Internet, customers are money. Second, the APP has permission to read the album, mainly to facilitate you to upload the user's avatar or use the locally stored pictures when communicating. But many apps will also secretly scan photos in your phone in the background. Analyze your place, your favorite things and even your family through the photos in your mobile phone. Then, based on this information, you can accurately place advertisements. For example, if there is a photo of your baby in your mobile phone photo album, they will give you an advertisement for implanting baby products.

Third, it is more dangerous for the APP to get permission from the camera. Generally speaking, this application uses a camera to take pictures. But if they get your surroundings through your camera. This is scary, which means that your usual life may be monitored by them.

Fourth, the app wants to get the right to read your SMS. What they mean is that the reason is to avoid repeated registration. General app registration requires a verification code. In order to avoid repeated registration, you need to read SMS and MMS permissions. We will naturally think that some bad apps will get some personal information from you by reading your short messages.
