Why is the camera loading and taking shots without being touched?

[Windows Central Question]

While my Nokia Lumia 920 is sitting untouched in screensaver mode, the camera keeps repeatedly loading and taking shot after shot until the battery dies. I thought it was a user error (e.g. like *** dialing), when I first had approx 600 shots of nothing on my camera roll, or I was just going crazy. Then it started happening all the time. Have tried soft reset. Anyone have a clue?

Check the physical camera button if its because of a phone protector OR if that has any dust or anything which might be causing it to be pressed always. you can also disable accidental camera press option in Settings > Photos + Camera.

Looks like the physical camera button has been short-circuited already. Try blowing dry air into the sides of the camera button while your phone is turned off (either by using a hand aspirator (the one used for cameras) or a canister of dry compressed... but never use your breath/mouth). You could also try to prevent your camera apps from launching when the camera button is pressed by changing the settings (if you can make it to your settings at all). Lastly, you may have to bring your phone to a service center.
