Microsoft is working on a pair of high-end Lumia smartphones set to debut later this year. Both models sound impressive on paper but it’s the flagship device, codenamed Cityman, that’s likely to draw the most attention.

Unleash the Phones has it on good authority that Cityman will ship with a large 5.7-inch QHD display. It’ll be powered by a Qualcomm octa-core processor, 3GB of RAM and 32GB of internal storage that’s expandable via microSD card slot. Buyers can also expect a 20-megapixel rear-facing camera, a five-megapixel front shooter for selfies and video calls and a generous 3,300mAh battery.

The lesser of the two devices, internally referred to as Talkman, isn’t exactly a slouch. It’ll reportedly feature a 5.2-inch QHD display with a hexa-core Qualcomm SoC, 3GB of memory and 32GB of flash storage with the same microSD card slot should you need more space. Talkman will also have a 20-megapixel rear camera, a five-megapixel front camera and a slightly smaller capacity 3,000mAh battery.

Both handsets will use 64-bit processors and while the source didn’t reveal exactly which chips will be used, the publication optimistically assumes it could be the Snapdragon 810 or 808. The phones will share a rear-facing triple-LED flash with each light having a different shade in order to provide more accurate images (think skin tones).

On the software side, Microsoft will introduce a new feature similar to Apple’s hand-off that’ll allow owners to receive calls on the phone but answer them on their Windows PC. Conversely, users will be able to initiate calls on their PC which of course will be handled through the phone.

Both phones are expected sometime during the second half of the year once Windows 10 is available for mobile devices.

Unleash the Phones has a solid track record when it comes to Microsoft rumors but as always, keep in mind that it’s just that – a rumor.
