If you haven't found it yet it's under 'advanced features' in settings. Under side key it gives you a quick launch option for the camera. I have mine as opening Bixby. You should be able to navigate it from the advanced features depending upon what key you use to lock and unlock your phone.
Seems like this helped thank you!. I was not pressing the button twice, just once to lock it or unlock it but the camara was opening also...thanks again
Mine is doing the same thing. Suddenly opens every time I touch the power button to open the phone. It's doing it with a single tap, not a double. I can turn off the quick access altogether but then I can't quick access my camera when I need it. Seems like an error in the latest update.
