When I install a new app it shows me the rights it desires and I have no chance to manage them as I like. Take it all or nothing is the choice.
Now fairphone has a root access.
So: is there a superuser app with which I can revoke later on rights I was forced to grant while installing an app?
To revoke internet acces right you can use a firewall like AFWall+

If you want to revoque other rights, Xprivacy allows it, however itâs a bit more complex to use in my opinion.
If you are afraid of some security issue in one of this app, nothing prevents you from using both.
Go to âSystem settingsâ (button far left at the bottom of the phone).
Swipe down to 'Superuserâ
Tab and you will see all the apps that have âsuperuserâ rights.
Here you can alter the superuser rights.
It can happen that an app whoâs superuser rights are delete will not function anymore.
The app âPermissions Deniedâ should suit your aim. I have it installed for quite some time although I rarely use it (if ever). Be aware that some apps may sometimes malfunction or crash when denied a permission they count on having. The way XPrivacy handles this is smarter and should avoid most crashes but as mentioned above, XPrivacy is a rather complex tool (I didnât find it very usable for that reason).
Itâs a missed opportunity on Googleâs side that this isnât a default Anroid feature by now. Their fear of apps getting broken should be the app developerâs responsibility. Let me tell the app what it can and canât do, and the app developer should just make sure his app still functions (read: doesnât crash) without those permissions. For instance, if I revoke contact list access from an app, then I understand I wonât be able to use itâs âinvite a friendâ functionality, but the rest of the app should still function and if I try to access that friend-based functionality, it should gracefully inform me that the functionality is disabled, or offer some alternate version of the functionality.
But yeah, thatâs all a pipe dream. Such functionality was hidden yet accessible in Android 4.3 but entirely removed from recent 4.4 updates, so I donât see Google heading in this direction any time soon, especially not after the Play Store update that âsimplifiedâ the permissions model.
Once you have managed it to have xposed and xprivacy installed and up running, this is by far the best and most flexible way to regain control over what apps are doing on your phone and with your data - I will never use an android device without this tools
Thank you very much all. I am now using XPrivacy - yes, I donât understand every item, but for example I just installed skype and XPrivacy stopped it immediately from taking over the control of my phone
