Nokia to add Bluetooth 4.0 to all Windows Phone 8 Lumia devices

The upcoming Black update will introduce Bluetooth 4.0 to all remaining Windows Phone 8 Lumia hardware, as well as the Glance always-on screen tech, and RAW camera support for the Lumia 1020 and 1520.

Bluetooth 4.0 allows users to sync their tablet or smartphone with another device without consuming as much battery power as a standard Bluetooth connection demands.

The technology is widely used by fitness accessories, such as heart monitors and some smartwatches.

Nokia is yet to announce when the Black update will be distributed.
