Duane came across something recently, so i checked out my phone and sure enough I was similarly affected.
It seems that some apps, when installed, take certain liberties with your privacy. Case in point, USAA, a once trusted company, and perhaps they still are like many other companies has its own phone app. When you check the permissions box, you are giving them permission to access your photos, your microphone, and your camera.
Begs the question as to why they would need to listen in on you, view your family pics, and be able to look at you and your surroundings whenever they like...
Go into the settings page on your phone, then to every app you downloaded and click on each one. I found that about a quarter of them were listening and viewing on my phone's camera. I disabled all those permissions.
Everyone is different, but for me, I only want the company or person on the other end of my phone to get what I feel comfortable in releasing, and nothing more.
FYI
