what is mobile app permission?

Do you know what app permissions are and which apps should allow which permissions? If you know it, that's a very good thing, but you don't, then please read this article from cover to cover. Read it carefully so you understand what it means to click the allow button when downloading a mobile app.

Many mobile users nowadays download applications from third-party websites and ask for permission when installing this application. Then they quickly click the "Allow" button because they don't know how to click the "Allow" button. By doing so, they have obtained permission to run the app on their phones.

 

  Permission is permission, allowing you to do this. When you download an app from the Internet, it needs some permissions to access it, such as B. Camera, Contacts, Microphone, Phone, SMS, Calendar, Location and Storage. But what does it mean to allow all of this? It just so happens that we get to know it bit by bit. Before that, let us know what types of permissions are there and what are they.

.There are 2 types of App Permission fair App Permission and Unfair App permission.

 Fair app permission. An application that asks for Camera, Location, Image permissions is called fair App Permission.

Unfair app permission.If you have installed any camera application and it asks for the permission of contact, SMS apart from camera, image file, then it is called Unfair App permission.

Why do apps want permissions?

While users worry about the privacy implications of app permissions, the simple fact is that even the simplest apps require permissions to function.

 For example, a "flashlight" app can turn on the camera flash so it can be used as a flashlight. Even such a simple app requires permission for flashlight control to work as advertised.

 To complicate matters for the user, the app developer cannot edit the details of each permission and therefore cannot provide any information on why each permission is required. This information can be included in the description of the app itself, but without each individual permission when the user views it. Users must first understand what the app is supposed to do, and then evaluate the permissions the app requests to determine whether they are appropriate.
