Microsoft may next month announce the “last Lumia” smartphone, as uncertainty surrounds the company’s plans for this market.

According to Windows Central, the company’s Windows 10 Mobile-powered Lumia 650 will make its debut on 1 February, although it will be something of a low key launch. It would boast an uninspiring feature set, sitting a long way below the more capable Lumia 950 line.

While other Lumia devices were planned which would flesh out the mid-range, the report said that these have been cancelled.

If this is the case, it is also unclear what Microsoft has up its sleeve for Mobile World Congress. While it has, following its acquisition of Nokia Devices & Services, held one of the key opening press conferences, it may not have much to show at the end of February.

Microsoft is expected to shift to a more Surface-like model with its smartphones, in line with its plan to focus on high-end and business users. While the Surface tablet business undoubtedly encountered some teething troubles, it has matured into a solid business.

But it seems unlikely that a Surface smartphone will make its debut at Mobile World Congress, with a Q4 unveiling, Microsoft’s standard timing for a Surface update, more likely.

Mooted specifications of Lumia 650 include 5-inch 720p display, Snapdragon 210 or Snapdragon 212 proccessor, 1GB of RAM, 8GB of storage and microSD expansion slot.

Available in black or white, it would also have 5MP front and 8MP rear cameras.
