The best use for phone cameras I have seen was at a part supplier, an electrician sent his apprentice to pick up a blue whatsit like they got 3 months ago the apprentice lined up every thing we had that could match the despription and sent the pictures to someone on site to compare to the existing unit. He reckoned he did things this way a lot and it made life much easier.
