Default android camera app has access to camera, microphone, location, storage and telephone.
Microphone may potentially seem OK if you want to record video? But not a good permission for photos only.
Location - if you wnat to geotag photos.
Storage, obvious as need to save files.
But telephone permission? Nasty, nasty, nasty.
.. and if you remove thaat telephone permission, the camera app will not work (& other camera apps rely on that so a bit stuffed!)
So, its all well and good being concerned about apps you download, but inspect pre-installed apps for the odd WTF moment.
