The Lumia Cyan update for Windows Phone 8.1OS

Lumia Cyan is the third firmware update from Nokia's mobile division, now owned by Microsoft. Lumia Cyan is distributed in parallel with the Windows Phone 8.1 OS update, and provides the necessary drivers and APIs for specific Lumia devices. As such, it enables unique Lumia features like the PureView camera, Living Images and an updated Creative Studio editing app, in addition to optimizing the battery, performance, Bluetooth 4.0 LE, a revised Camera app and general telephony functions.

Other features of the Lumia Cyan update will be dependent upon specific hardware. For example, the Lumia 930, Lumia Icon, and Lumia 1520 are expected to receive SensorCore support for a built in pedometer and exercise features. Those three phones will also have new camera algorithms applied to improve the quality of photos.

Miracast support for select devices will also be facilitated with the Lumia Cyan update, allowing users to stream media and mirror their phones on Miracast compliant devices, like TVs and computers.

Lumia Cyan will let users set the ranges for brightness levels. For example, you can have your 'low' setting very low, or make the 'High' setting less intense.

Nokia Treasure Tag support will come with Lumia Cyan due to the inclusion of a revamped Bluetooth 4.0 LE stack. (Early adopters of the Windows Phone 8.1 Preview for Developers had Bluetooth 4.0 LE removed due to incompatibility issues).

Dolby Digital Plus recording ability, the first of its kind in mobile, is anticipated to be enabled in the Lumia 930, Lumia Icon and Lumia 1520, once again due to their unique hardware with newer Qualcomm chipsets.

The Lumia Cyan firmware update and Windows Phone 8.1 OS refresh began to roll-out over-the-air on June 25th, 2014, but only for the Lumia 925 in Finland and also in Argentina. The update will arrive for other phones throughout June, July and August, depending on the Lumia model, carrier (if applicable) and country/region.

Before starting the Lumia Cyan update, we recommend that you make enough space on your phone. Having about 1.5GB free phone memory will ensure that your software update goes smoothly. To check for available free space, go to Settings > storage check (storage sense). In the below Software Update FAQs you can find detailed instructions on how to clear up some space on your phone and other tips to help you, for example if you encounter an update error.

The Lumia Cyan update with Windows Phone 8.1 consists of two parts, and after the first update your phone will automatically check for updates again. Follow all the update prompts so that you don’t miss out on any of the goodies.
