Leaked images of Nokia Lumia 630 detail the specification of the first Windows Phone having on-screen buttons.
The images, leaked on Evleaks, provide an early look at one of the first handsets running on the new OS update.
According to The Verge, the handset, codenamed Moneypenny, with 'softkeys'- the on-screen buttons, has been primarily designed by Microsoft for low-end Windows Phone 8.1 handsets.
The report said that it is unclear what specifications Nokia is planning for its Lumia 630, but some rumors have suggested it would include a 4-inch screen and 1GB of RAM.
Nokia is also speculated to be working on a dual-SIM version of the Lumia 630, dubbed Lumia 635.
