UPDATE: Sorry folks, these devices have been cancelled. According to our source, as well as WCthe Lumia 850, 750 and 650 are the Honjo, Saana, and Guilin devices and they’ve been cancelled. It’s worth noting that Microsoft is currently using these devices to test Windows 10 Mobile internally, however.

Original article follows below.

The Lumia 950 and 950 XL may be the Lumia devices that everyone knows about, but apparently that’s not all Microsoft has to offer.

According to a tip from a source who wishes to remain anonymous, Microsoft is also planning 3 additional Lumia devices – the Lumia 550, 750 and 850.

Lumia 550

The Lumia 550 is the low-end budget Lumia here, offering a Snapdragon 210 paired with an Adreno 304 GPU, 1 GB of RAM, 8 GB of internal storage and  a microSD card slot which offers a storage ceiling of 208 GB (200GB SD card + 8 GB internal storage).


The device is also said to have a 5” qHD Gorilla Glass 3 screen, along with a 5 MP rear camera with autofocus and a 2MP front facing camera. While the screen resolution is less than the resolution of its immediate successor the 540, Microsoft may be intent on keeping the 5xx line as its low-budget line and cancelling out the short-lived unprofitable 4xx line. Under this context slightly reduced specs make more sense. In addition, a qHd screen would be far easier for a device equipped with a Snapdragon 210 to handle. Here are the Lumia 550 specs in one simple list:

  • Qualcomm Snapdragon 210 MSMM8909 4xCortex-A7 cores @ 1GHz
  • Adreno 304 GPU
  • 1GB RAM / 8GB internal storage + micro sd
  • 5″ Screen 540×960 GG3
  • 5MP 2592×1936, autofocus, LED flash 480p@30fps + 2MP ffc
  • Wi-Fi 802.11 b/g/n, DLNA, hotspot
  • BT v4.0, A2DP, LE, apt-x
  • 1905mAh battery
  • GPS IA-GPS GLONASS), Accelerometer, proximity

Lumia 750

Moving on, we also have specs for the midrange Lumia 750 which we assume to be one of the two Microsoft business focused devices along with the 850. The Lumia 750 will have a Snapdragon 410 processor clocked at 1.2ghz paired with an Adreno 306 GPU, a first for the Lumia line. Its screen size and camera receive a bump to an 8 MP Zeiss lens and a 5 inch HD screen.


The 5 MP front facing camera from the Lumia 730  and 640 XL will be retained for maximum selfies, hopefully with the influx of new apps Windows 10 should bring. Rounding out the specs are a healthy 2650 mAh battery, 8GB of built-in storage with SD Card support for a potential 208 GB of storage for apps and media and support for LED notifications. All things taken together, the 750 sounds like a worthy upgrade to the 730. Here are the full specs of the Lumia 750 in one simple list:

  • Qualcomm Snapdragon 410 MSMM8916 4xCortex-A53 cores @ 1.2GHz
  • Adreno 306 GPU
  • 1GB RAM / 8GB + microSD
  • 5″ Screen 720×1280 GG3
  • 8MP 3264×2448, Zeiss optics, autofocus, LED flash 1080p@30fps + 5MP ffc
  • Wi-Fi 802.11 b/g/n, DLNA, hotspot
  • BT v4.0, A2DP, LE, apt-X
  • 2650mAh battery
  • GPS (A-GPS GLONASSL) Accelerometer, proximity, luminosity, led notification

Lumia 850

Finally, we have the specs of the Lumia 850. Like the other two, it is equipped with a 5 inch screen although it gets a WXGA screen rather than a HD or FHD screen.

Similarly to the Lumia 750 it comes with a Snapdragon 410 albeit one which is clocked at 1.4 ghz rather than 1.2 ghz. It is equipped with 16 GB of internal storage that can be expanded up to 216 GB via Micro SD.


Optics wise, it is said to have a 10 MP PureView Zeiss lens camera with a 5 MP camera ( a standard feature?). The spec sheet lists support for video up to  480 p @ 30 fps which we’d tag as being likely due to prototype status. The battery is the same as the 750 with 2650 mAh, which paired with the screen resolution and SD 410 should provide decent battery life. Here are the full specs of the Lumia 850:

  • Qualcomm Snapdragon 410 MSMM8916 4xCortex-A53 cores @ 1.4GHz
  • Adreno 306 GPU
  • 1GB RAM /16GB + micro sd
  • 5″ Screen 768×1280 GG3
  • 10 MP 3520×2640, Pureview, Zeiss optics, flash + 5MP ffc
  • Wi-Fi 802.11 b/g/n, DLNA, hotspot
  • BT A2DP, apt-x
  • 2650mAh battery
  • GPS IA-GPS GLONASSL proximity, luminosity, led notification

The specs given are prototype specs and subject to future alteration, but that appears to be what Microsoft’s working towards at the moment. While Satya’s email may have given some doubt towards the future of the Lumia line, it appears that Microsoft is instead cutting off devices like the 635, 638, 636, 920 T, 532 etc and “focussing” them into one main device instead.

Our source also had some words to say about the Windows 10 update for mobile. He/she revealed to use that Microsoft had set September as the target for completion of the OS, with October being the target for OTA updates.

This matches with the rumored dates of the Lumia 950 launch (at IFA most likely), Windows 10 Update 1, andthe French carrier target dates. Assuming this is accurate, Windows 10 mobile still has one more month of active development and feature additions to go.
