At times, this can be crucial to the basic function of an app. At other times, such access can be a helpful convenience that allows the app to function more broadly, but it is not critical to the core mechanism of how the app functions. Some of the key additional findings in our analysis of the permissions in the Android marketplace include:. The two most common permissions sought by Google Play apps help the app access the internet.
The third- and fourth-most common permissions allow apps to access memory on the phone, a feature apps would need in order to save content to the device. By category, communication and business apps require the largest number of permissions.
Google breaks apps into 41 different categories, and app developers then choose which category they want their app to appear in. Communication apps require an average of nine permissions, while business apps require an average of eight. A table running through all the categories and examples of apps in each category can be found here. The largest number of app permissions relate to hardware, rather than user information. To better understand what information apps could potentially access, Pew Research Center placed permissions into broad categories: 1 permissions that allow an app to access a hardware function of the device or 2 permissions that could potentially give the app access to any user information.
Using this distinction, 70 permissions could allow an app to access user information, while allow an app to control some hardware function of the device, such as allowing the app to control the vibration function of the device or control the camera flash.
As of fall , the overwhelming majority of Android apps have been installed by only a small number of users. On the other end of the spectrum, a relatively small number of apps have been installed by vast numbers of users — a total of four apps have been installed over 1 billion times. Complicating the matter even further for users, app developers cannot edit the description of each permission and therefore cannot include information about why each permission is needed.
