I have a Samsung Galaxy S5 (the blue one just to help set the scene) running Android version 4.4.2
My phone was sleeping beside me peacefully on my desk in standby mode (or whatever you call it when it's just a blank screen not being used).
Suddenly, the screen lights up and to my surprise the camera is active - with no human intervention whatsoever. There were also no notifications of any kind at this point that might have had a hand in it.
What could be the possible causes for this to happen? Are there any conditions is which this might be expected? Is it a bug? Or maybe worse, could it be a malicious application trying to "catch me in the act"?
Additional information that might be useful:
- When the camera started it was the main camera that was active, rather than the front camera
- Looking through the phone and camera settings, there is nothing enabled (or even available) that might explain this happening. For example, there is no quick start camera gesture or voice command
