On my Samsung Galaxy S2 I9100 with CM11, I always hear a very subtle click of the autofocus whenever the camera app is loaded. Since some weeks, I heard that sound randomly, especially after every restart and reconnect with WiFi. This somehow scares me and looks a bit like my phone is supervised. Is there a possibility on android (with / without root access) to find out which task uses the camera?
Install the Permissions app, and look the the apps under
take pictures and videos.
XPrivacy seems to be the tool of choice for these issues, although a bit tough to get through all the settings. Could not find the spying app yet, but will keep this post updated.
