After the Lumia 850 was showed in leaked renders, another Microsoft smartphone, tipped to launch next year, has appeared online. The phone was first spotted back in October in black, and now we have a chance to see the white variant of Microsoft's fourth Windows 10 handset.

Codenamed Lumia Saana, the Lumia 650 will join the Lumia 950, Lumia 950 XL, and Lumia 550, and by the time it becomes official, Microsoft might announce the Lumia 850. There is no word on when to expect the phone except it will be announced sometime next year.
