How to take better pics using your nexus devices on 4.2

I notice on the nexus device camera you have to hard press and hold the camera button and wait until the dialer lock into place. its a twisting dialer that goes from left to right from 9pm to 12. There is a green light at 12 o clock. You have to let go of the shutter button when the dialer hit 12 o clock. Simply just slightly tapping the camera shutter button cause the screen to get a lil out of focus but it produces a clear shot also.....try it out.

In low light use these settings. Turn on flash....change the iso/white balance to -2. pics should use way less light and get better pics
