Mats Lindoff, Sony Ericsson's chief technology architect, said that the firm had been testing Android with prototype devices, and that Google's was a " holistic" approach.
"[But] to go with mass production and working with prototypes are two different things," he explained. "If you want to give every service away to Google, then Android is the perfect solution."
