The Lumia 640 XL was announced on the 2nd March at Mobile World Congress 2015 and is set to hit the market in April, but Microsoft has already started uploading support videos for the handset.

The 5.7 inch HD phablet features a 13 megapixel rear camera, 5 megapixel front camera and a massive 3000 mAh battery.

The above video explains the keys and parts of the device, and below Microsoft explains the tricky process of removing the shell to replace the SIM and memory card.

The handset is set to cost a very reasonable $240 at launch, which makes it one of Microsoft Mobile’s best value for money handsets yet.
