Many pre-installed apps facilitate access to privileged data and resources, without the average user being aware of their presence or being able to uninstall them.

On the one hand, the permission model on the Android operating system and its apps allow a large number of actors to track and obtain personal user information. At the same time, it reveals that the end user is not aware of these actors in the Android terminals or of the implications that this practice could have on their privacy. Furthermore, the presence of this privileged software in the system makes it difficult to eliminate it if one is not an expert user.
