Struggling phone maker Nokia has unveiled two new handsets it hopes will revive its fortunes.
At the start of the world's largest mobile phone trade show in Barcelona chief executive Stephen Elop said the phones - a low-price €189 (£160) smartphone that runs on Windows software and a handset with a high-resolution 41 megapixel camera - demonstrates "the actions necessary to improve the fortunes of Nokia".
"With great products for consumers, I think the rest will fall into place," he said.
Analysts said the new smartphone could attract users because of its low price but investors sent Nokia shares down more than 5%, erasing a big boost it gained on Friday in anticipation of new announcements at the trade show.
Nokia has lost its once-dominant position in the global phone market, with handsets running on Google's Android software and iPhones enjoying booming popularity.
The Finnish company is attempting a comeback with smartphones using Microsoft's Windows software in what Mr Elop has called a "war of ecosystems."
