Engineers who used to work for Nokia are hoping to grab a share of the lucrative and highly competitive smartphone market with a new handset, which is based on the former world No. 1 mobile phone maker's old software and is faintly reminiscent of its recent models.

The Jolla handset's Sailfish platform has been developed from the MeeGo operating software, Nokia's last open-source platform which it abandoned in 2011 when it switched over to using Microsoft's Windows system.

"Different": The Jolla smartphone.

The sleek 4.5-inch phone, which almost looks like it could be part of Nokia's Lumia range, features an eight megapixel camera, supports fast 4G internet connections and includes the well-received Nokia's HERE mapping services that cover more than 190 countries.

But, unlike Nokia's phones, Jolla is also compatible with more than 85,000 apps provided by Google's Android, the popular and dominant operating system that has helped Samsung overtake the former Finnish bellwether to be the world's largest mobile phone maker.
