Do you know that you don’t have to tap the capture button on your screen to snap a picture? You can actually just press the volume up/down button. That’s just much easier, isn’t it?
Also, do you know you can take multiple photo bursts all at once by simply holding down the capture button or the volume up/down button? your phone will take a series of rapid shots, or bursts, in quick succession. This is especially useful if you’re photographing a moving subject. Later you can scan through all the bursts and pick your favorite ones.
