Nokia unveiled a lighter, metal model in its Lumia smartphone range, as it tries to catch the eye of buyers to close the huge market lead of rivals Samsung and Apple in the lucrative handset market.
The Lumia 925, to be sold for $610 before taxes and subsidies through carriers such as Vodafone and China Mobile, is the latest in Nokia's range using Windows Phone software, on which CEO Stephen Elop has pinned the future of the loss-making company to reverse a dramatic drop in revenue over the last two years.
The phone weighs 139 grams, compared with 185 grams for the earlier 920 model, which some critics had said was too heavy.
The new phone will be rolled out globally starting in June, and is due to be sold in the United States by T-Mobile.
On Friday, Nokia unveiled the Lumia 928 for the U.S. market, priced at $99 after a rebate and a two-year deal with Verizon Wireless.
