Very useful! I had a better result in my phone using the intent STILL_IMAGE_CAMERA instead of IMAGE_CAPTURE.
IMAGE_CAPTURE opens some sort of subset of the camera application and even requires confirmation for the photos taken and the other one opens the actual camera application that I'm used to, with all the settings.
