Things seem to be settling down around the debacle that was the permissions in the Facebook Messenger app. Now, Facebook finally has added a page to its help section explaining what’s going on, and why the app uses the permissions that it does. And — as expected — Facebook’s explanation is exactly what it was expected to be. There really is nothing to be alarmed over, so far as the app permissions are concerned.
FB Messenger can access phone numbers, cost you money and read phone status and identity. Of course it can, you can call people with it. With regard to testing, it can read, send, edit your SMS and MMS messages because it uses that information to confirm your number and allows you to text non-FB users. It can access the Camera to take pictures just like it can access your microphone – so you can call and make messages. The list goes on and on: GPS, SD, Accounts, Network – all so the app can do what you need it to.
