A small selection of the hundreds of mobile phones that are analysed by the DFU on a regular basis.
The unit also probes phones for the City of London Police to allow it to develop tools and resources to tackle the variety of phones on the market.
Foggon says the DFU can cope with all of the major brands but still comes across handsets that leave it stumped, such as an Amoi phone that initially had it baffled.
The DFU has two attached officers from the City of London Police, soon to be increased to four, and provides evidence for a wide range of cases such as people trafficking.
