quick picture taking
this is probably old news but I just found this cool trick. While taking a picture I left my finger on the screen and ran it down the screen without lifting it. Moto x rapidly took a quick succession of pictures. So long as I ran my finger down the screen it would take a picture. I took a total of 5 quick pics before I ran out of screen space. Probably old news but jus thought I'd share.
Re: quick picture taking
you don't have to move your finger just hold it on the screen for the quick pictures feature!
