How can I add a photo to a job?

From the Job Fault screen click on Photo.

This will launch the camera.

When the device shows the scene you wish to capture then click Take.

The application will now show you a preview of the photo just captured. If you wish to add the photo to the job then click Continue; if you are unhappy with the photo taken then click Retake Photo.

The fault screen is not the only place you can take a photo, any job screen with the "Take Photo" option will allow you to take a photo.
