Depends on the dumbphone.

With a smartphone you have to turn it on, swipe your password and/or unlock it somehow, then tap the camera app and then tap/press something to take a picture. And you might get an error message, "Battery too low to use flash."

My dumbphone you press-hold camera button and that's it.

With a generic "smartphone" you do, with an iPhone you just swipe up from the bottom right corner. It's nicely sandboxed outside the lock screen - you can see the photos you just took, but to review other photos you need to enter your PIN.

Newer Android phones (4.0 upwards I believe) also allow quick camera access from the lockscreen.

Sony smartphones work the same way
