|Cameras in my Nova Launcher menu|
|Samsung Camera UI|
Obviously there were issues with the camera app that came with my Samsung Galaxy S3 that made me start looking for an alternative. The most egregious problem was that the camera app kept losing its settings, especially my selection of short-cuts, if I was storing photos on the phone (as opposed to the SD card). The other issues were the interface and functionality was pretty basic, and when launching the camera from the Cover lock screen I couldn't switch to the video camera.
