Nokia's return to the mobile space is happening end of 2016 with the leaked Nokia C1
A while back Nokia's CEO Rajeev Suri confirmed that although the firm had sold its smartphone business to Microsoft, the timeout on an agreement between the two companies would be expiring in Q4 2016 - at which point Nokia is free to act on its plans to re-enter the phone market. We've also heard whispers about the handset that will herald this return - the Nokia C1.But as of April 4 it appears the C1 isn't the only Android device Nokia is working on; we now have details of an alleged mid-range device called the Nokia A1 (scrap that: the A1 was an HILARIOUS April Fool's joke). A render has leaked via Android Authority showing a somewhat similar design to the C1 (pictured further down this article). AA's "trusted insider" said this is a mid-range device and it appears to be running Nokia's Z Launcher over Android - a similar setup to the Nokia N1 Tablet. There's not much else to go on at the moment and we're left to simply ogle the new design and speculate on the specs.
