Stand in front of a DigiVan screen. Tap Open camera, fit the screen inside the frame, press the shutter. Then copy the report and send it to Barbara.
1. Does the live camera work here? 2. How big are the photos? 3. Can the page set exposure or shutter speed? 4. Sharpness, light and LED lines on three quick shots. 5. The phone's own camera as a fallback, and whether its photos carry a location.
Copy this and send it to Barbara with a note of the phone, the time of day and what the screen looked like to your eye.
