Android lost a huge ally at Samsung Mobile this week, with the departure of Omar Khan. The CTO is leaving the hardware manufacturer for the industry analyst side of factors, joining Citigroup’s mobile solutions team. Khan has led the charge on numerous Android-based devices, including, recently, the S II and diverse other products within the Galaxy line — he also made a memorable appearance at the Engadget Show, back in August of last year. Samsung’s Nick Dicarlo and Gavin Kim might be stepping in to seize a number of Khan’s PR responsibilities on the company.
