On multiple occasions, the native camera applications opens itself. This can even happen when the phone is locked and posed an a table. Is there a way to prevent this problem, or is this a harware one ?

  • Is the camera button loose, or does it launch on a hair-trigger? If so, it could be the button. Also what model phone do you have?

  • A lumia 520. I thought about the button, but it is stuck and doesn't launch camera when I push it.

    If it is stuck, it could very easily be stuck in a position which is causing your issues. Also, you should be able to take the back cover off, which supports the button, and reposition it.

Sometimes buttons can get jammed, if you get a crumb (or something else) stuck in there, which makes the phone think it's constantly being depressed.

For phones that have a removable cover (like the 520), removing the cover, and cleaning with a dry microfiber cloth may dislodge it.

For phones that do not have a removable cover, the best option would be to take it to an authorised repair centre, who might charge you an extortionate amount to do the same - if you're brave, and don't mind risking voiding any warranty, you might be able to dislodge anything fouling the button with a mini-vacuum, or air blower (similar to those used for cleaning DSLR sensors). If you do try this approach use the minimum amount of force required, to risk damaging the device - if you're unsure, take it to a servicing professional.


You can try changing the side button. I had similar issues, Nokia store replaced that faulty button
