So I recently discovered some features I hadn't known about with the Moto G's camera. After wondering why I wasn't getting geo-tags with my photos, I Googled around a bit. When you slide right in the camera app, the options pop up. From there, you can scroll the wheel up and down to reveal more options, including: geo-tagging, widescreen & 4:3 mode, sound on or off. They don't discuss these features in the tutorial, so hopefully this helps others!
