One of the banner features of owning a Lumia PureView device tends to be the dedicated camera button. It seems like a small thing, but once you start using one, it is hard to go back to just a software camera launcher.
A neat trick that Lumias like the Lumia 950 and Lumia 950 XL have enabled out of the box is a feature to prevent accidental camera launches when in your pocket. It works by enabling the front sensor near the earpiece for proximity detection. You can try it yourself by covering the top front of the display with your finger and then trying to launch the camera button – it won't work.
The idea here is smart: if the Lumia is in your bag, purse or pants you do not want to hit accidentally the camera button and have it and the display active and draining your battery (and taking boring photos).
However, there can be some side effects too.
I sometimes pull the Lumia out of my pocket or bag while pressing the camera button at the same. Sometimes you want to be quick, right? Other times my hand may trick the sensor as I'm framing the photo. The result? I hit the camera button, and it doesn't seem to register.
Nothing it worse than a stuck button and if you have experienced that at least you now know what is causing it. Your button is fine, but the accidental press feature is doing its job.
Personally I like to disable the accidental launch feature. For one, I do not notice my camera launching when it shouldn't and two, the camera button feels more consistent now. Each button press is 100% guaranteed going to launch the camera no matter the environment.
Disable Accidental Camera Launch feature
1. Settings

Navigate until you find Prevent accidental camera launch when the device is locked and toggle it to off. The effect is immediate and does not require a restart.
