I have noticed that on most of the Android app under BB10 OS, you can't change the Application Permissions and deactivate them, for instance.

Is it due to the Android runtime environement, or is it that most android apps do not allow these settings?
Is there a way to change that?

It first struck me with WhatsApp, when I was trying to install it and juggling between the BB and the Andrd version. One was editable and the other not at all! But WhatsApp is not the problem anymore I guess... But there are still some other interesting apps only under Android
