If you were not aware, but FB requires those who use their mobile/digital phone to access FB to d'load and use a specific application to access FB. However, that app gives FB access to everything on the mobile/digital 'phone.
BTW. Our supposed name shown here is an ens legis name created by Facebook. As the man we are known as Colin-Stephen:[Tonks], but that is not accepted by FB, so we advised them that they are the TRUSTEE and SURETY of their creation.
Apps need permissions to access certain aspects of a phone. Facebook is no different.
If you want to take a picture directly through Facebook it needs access to the camera. If you want to send an audio message it needs access to the microphone. Facebook isn't the only app on my phone, or yours,that needs access to all of these things. But because it's Facebook everyone gets into a panic. I'm not saying Facebook is the most angelic company on the planet but.........
