Still, Elop, who has worked as Nokia's CEO for two years, said Nokia has made "strategic changes" to the company since February 2011 when the company outlined a new strategy, which included leadership and operational changes.
"We declared that there is an issue and now we are step by step demonstrating how the full power and might of Nokia can be brought to bear on the next smartphone experiences," Elop said.
Making smartphones that run primarily on Microsoft's Windows Phone software was part of the company's major changes, Elop said.
Nokia introduced the first series of Lumia smartphones in late October last year, but the company is really placing its hope on the launch of its latest Lumia phones.
"There's a lot more steps ahead. What we have to do as a team is make sure this translates into the right level of consumer interest and delight," he said. "And based on the reactions we are seeing even here today, as we show off these new capabilities, we're very hopeful of what this represents."
Nokia and Microsoft's announcement comes just before Apple's announcement next week, where it is widely expected the company will announce its latest iPhone. (Read More: Apple Will Make Big Announcement Next Week, Hints at iPhone 5 )
