The new stock camera found on the Google Play Editions of the Samsung Galaxy S4 and the HTC One is so much cleaner than it's predecessor. The menu system has more of a stack flow which keeps it out of the way of your display while you are trying to frame a picture. You can have this new camera right now. It can be installed on any device, and it does not require you to be rooted. Simply download the camera app from the link below and install the same way as you would any other sideloaded apk. The app will then populate in your app drawer. This does not replace your current camera, unless maybe you are on a Nexus device, it will just give you another option. This also comes with the stock gallery.
