Google's dominance of the web will not translate to the mobile phone market, a senior executive at Symbian has said.
John Forsyth, vice president of strategy at Symbian, the platform that powers many of the world's phones, said Google lacked experience.
Google has formed an alliance with 33 firms to develop an open platform for mobile phones, called Android.
Meanwhile, the head of Nokia in the UK said the firm was in discussions with Google about using the platform.
Simon Ainslie, Nokia UK's managing director, said: "We are always open to discussion and debate on that. We were not ready to make any commitment to it or discuss it at the time."
"We are having ongoing discussions with Google."
