Omar Khan, the CTO and chief product officer at Samsung Mobile, is leaving the company to head up Citigroup's mobile banking services. The Droid Guy, a blog on Android news, published an e-mail from Khan, in which he said he will start next week heading Citi's global mobile operations. Khan joined Samsung in 2008 after previously working in the top management at Motorola. He helped launch the company's first smartphones and Android device range.
