Nokia may have designed a futuristic handset on a par with Motorola’s wacky Aura or any number of Vertu’s pricy phones, according to what's claimed to be a leaked internal video.

A CGI video mock-up of the phone – thought to be called Erdos – has been leaked online. The device’s looks have already led many to speculate that Nokia has selected the handset as a replacement for its existing 8800 device.

For example, Erdos features the same pull down keyboard cover as the one found on the 8800. However, do this on Erdos and you will be met by a “revolutionary raising keyboard”, the video states.

Erdos’ screen ‘appears’ on the phone’s silver surface – just above the keyboard. The video refers to this feature as a “Go-silver OLED display”.

Quite how this works isn’t yet clear. One explanation is that the silver surface above Erdos’ display can transform into a transparent state, revealing the OLED screen underneath.

Team this up with “tap-sensitive controls” and a rear-mounted 5Mp camera, and Nokia may have designed itself a sure-fire seller to WAGs, bankers and company executives.

Erdos is rumoured to have 8GB of internal memory – yet no expansion slot. The video also shows the phone slotting into what looks like an oddly shaped docking unit with stick-out speaker.

Since Nokia hasn’t officially confirmed Erdos’ existence yet, a launch date or price isn’t known. ®
