Nokia's 'Lumia Amber' update is rolling out to its range of Windows Phone 8 devices this week. The update, that was originally due to launch in July, includes a number of Nokia specific app additions, and Microsoft's latest Windows Phone 8 version. Nokia is adding its Smart Camera software, that originally debuted with the Lumia 925, to its range of devices, adding the motion focus picture options.

The Lumia 920, 925, and 928 will all get Nokia's Pro Camera app that originally debuted on the Lumia 1020 recently. The app allows owners to adjust exposure settings such as ISO and shutter speed, and includes manual focus and other in-depth shooting features. Alongside the camera apps, Nokia is also rolling out its Glance software for its range of Windows Phone 8 devices with the exception of the Lumia 520 and 625. Glance features a clock on the lock-screen, and lets users double-tap to wake up the device. Flip to silence, a feature that mutes incoming calls, is also included.

Nokia says the update will start for the Lumia 920 and 820 in selected countries, as well as the Lumia 521, 810, and Lumia 928 in the US. Delivery won't be instant to all Lumia owners, as operators worldwide are rolling out the update on different schedules. Nokia expects the update to be made available fully to its range of Windows Phone 8 handsets by the end of September.
