Schmidt made his comments after Gartner's chief of research for mobility and communications, David Willis, explained to Schmidt that Android is not secure.
"If you polled many people in this audience they would say Google Android is not their principal platform... When you say Android, people say, wait a minute, Android is not secure."
Schmidt quickly replied: "Not secure? It's more secure than the iPhone."
Reportedly, the audience laughed at Schmidt's response, as he then explained that Android's billion-plus activations put it through vigorous security testing.
Android is often criticized as being a fragmented platform, and Schmidt was quick to shoot down. "With Android we have an agreement for vendors that you keep the Android stores compatible and that is a great breakthrough for Android," he said.
Schmidt closed with saying how users "will be happier with Gmail, Chrome and Android more than you can possibly imagine" and reiterated his belief that "Android is very secure."
