Technology giant Microsoft, which is expected to release the high-end Lumia 950 and Lumia 950 XL at an event on 6 October, is tipped to release yet another smartphone on the same day. The handset has surfaced via AdDuplex research.

The report, made public by Alan Mendelevich (founder and CEO of AdDuplex) was spotted by NokiaPowerUser, which has hinted at the existence of a newer mid-range Lumia smartphone. However, the device might-not necessarily fall in that category, as Mendelevich has claimed the smartphone could feature a 5in display, while the latest trends show that high-end flagships feature at least a 5.5in display.

The smartphone could be named Lumia 750 or Lumia 650. These rumours add to earlier reports that hinted at Microsoft developing six new exclusively-branded Lumia handsets under a new Windows Phone hardware restructuring process previously announced by CEO Satya Nadella.

Another report claimed that, out of these smartphones, one device would feature a front-facing LED flash. However, the technical specifications of the phones are yet to be released officially.

Nonetheless, a report published in PhoneArena has hinted that the Lumia 750 would feature a Qualcomm Snapdragon 410 SoC. It would offer 8GB internal storage which could be enhanced by an external MicroSD card.

The device could also sport an 8MP rear camera and a 5MP front camera and may run Windows 10 Mobile out-of-the-box.
