Is it really necessary for Waze to know your position when you’re not using it? Or that the Flashlight accesses your contacts or messages? Maintain the confidentiality of your personal data by limiting the permissions granted to applications.
If the information is clearly displayed on the Android Play Store, who cares to read in detail the list of privileges required by the applications before installing them? However, these authorizations are very often unjustified, exposing without reason confidential data. Recent versions of Android are happy to revoke permissions granted a little faster.
Modify the privileges of an application
If your smartphone has Android 6 or 7, expand the notifications pane and then touch the gear icon to access the settings home page. Then open the Applications section, choose the app that seems a little too curious and touch the title Permissions to view the details of permissions. Simply disable those that you find superfluous or abusive. With Android 8, go to settings, tap Apps & notifications, App info and select an app.
Avoid inappropriate access to your contacts, photos, etc.
The previous method is appropriate if you have clearly identified which applications have abusive privileges. However, it can be laborious when it comes to managing permissions to access a particular type of data (camera, calendar, contacts, position, SMS, microphone, storage, etc.) In this case , go back to the Android settings and view the list of apps. Then touch the gear icon at the top of the screen and then titled App Authorization and designate the resource of your choice (contacts for example).
You only need to remove the rights to apps that make unjustified use of this data. However, act with restraint to prevent certain applications from working properly. Skype or Snapchat do need to use the camera or microphone of your phone!
