In light of the recent revelations, there was a company statement issued regarding these Samsung phones as personal equipment.
I raised a query regarding the potential for transport (as DG) in cargo, with our relevant folks. Specifically, whether there were any extra efforts beyond recording the carriage of Lithium cells in general, in the DG NoToC.
The reply that I got completely missed the point, but I was offered extra training/guidance in how to handle a personal phone using the big red book, when next I'm in the office.
