Last night I loaded on the following apps to test:
Camera PRO
Camera Zoom FX

Both actually worked with the camera, and once I removed the thin film that covered the lens from packaging, the camera resulted in a much better picture.

Both programs provided a much larger image and very good digital zooming. The one downside is for some reason I wasn't able to discover, the image was off by 90 degrees and no matter how I rotated the device or change the orientation, stayed off. Go figure.

Camera Pro looked very nice in that it had an active histogram to adjust the lighting, and a gret deal of options. The issue: NO SHUTTER BUTTON. And I could find no way to activate one. It seems to be designed for phones with a dedicated camera shutter button.

Camera Zoom FX worked, but had the same skewed image, but the menu allowed me to add a shutter button to the screen. So I was able to zoom, correct color balance and take a picture by clicking on the screen shutter. In zoom mode this meant the camera "bobbled" as my hands shook a bit whilst tapping the screen button, but it took and saved a photo and did not crash the camera system. Maybe the 1.13 version of Dingo I am running has corrected the issue people previously found with the camera.

So if your neck is flexible or you can visualize a picture skewed 90 degrees from reality, this app will run.
