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.

  • thanks, lots of apps there. I was looking for something like a task manager which shows the active task that just accessed camera functions, or a method to restrict camera access and show which tasks are asking for it. I have cerberus and wheresmydroid installed and could imagine them to stalk after my pictures, or potentially a virus. – aXeL-HH Mar 13 '14 at 7:52
  • @Axel Are there any pictures being taken? – geffchang Mar 13 '14 at 8:13
  • The camera is definitely being accessed since I see the camera lens moving every once in a while (once every 30 mins up to once every 15secs),and due to a hardware imprecision the lens touches the glass of the camera, which results in a very distinct click sound. Pictures don't show up in the gallery, but apps like Cerberus can do that easily without leaving any hint besides on my phone the click sound. – aXeL-HH Mar 14 '14 at 8:23

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.
