Today at Microsoft's Build 2014, Nokia announced three Lumia smartphones -- the Lumia 930, the Lumia 635 and the Lumia 630 -- based on Windows Phone 8.1 and a series of exclusive Nokia features. The Nokia Lumia 930 sports a 20-megapixel PureView camera, optical image stabilization (OIS) and ZEISS optics to achieve sharp shots and the flexibility to zoom into any shot after you’ve taken it. A HD 1.2 MP wide-angle camera adorns the front.

The Nokia Lumia 930 also possesses HD video skills with four microphones. This quad allows directional recording, which enhances the clarity of your subjects by rejecting the sounds outside the direction of capture.

The 930 has a 5-inch, 1080p Full HD display (1920×1080; 441ppi), with Gorilla Glass 3, Super Sensitive Touch and a near 180-degree viewing angle. It comes with integrated Dolby Surround Sound, a 2.2 GHz quad-core Qualcomm Snapdragon 800 processor, 32GB of internal storage (7GB free OneDrive cloud storage) and 2GB of RAM. Also built into the pillow-like design is an LTE quad-band chip and Bluetooth 4.0 LE. Other features include a 2420 mAh battery and built-in wireless charging.

The new Nokia Lumia 930 also comes with imaging apps such as Nokia Camera, Nokia Storyteller, Nokia Creative Studio and Nokia Refocus.

The Nokia Lumia 930 is priced at $599 before taxes and subsidies. It will be available from June – beginning in Europe, Asia, India, Middle East and Latin America – and will continue to rollout throughout the world (except the US) throughout the summer.

The Nokia Lumia 630 and Nokia Lumia 635 are both delivering a quad-core processor, 4.5-inch ClearBlack screen and a colourful design with changeable shells.

The Nokia Lumia 630 comes in two 3G variants, including the most affordable Lumia, and the first Lumia with dual-SIM.

These funky new smartphones are the first Lumias to see the Windows Phone navigation keys integrated into the user interface (UI), disappearing when watching video and when the phones are locked, as well as slick volume buttons, matching the shell.

The Nokia Lumia 635 and Nokia Lumia 630 also offer a new speedy Word Flow keyboard and social apps like WhatsApp and WeChat, plus Nokia Camera, maps and navigation from HERE, and free Nokia MixRadio streaming.

They also introduce 'SensorCore' low-power sensing, that enables exercise and exploration apps like Bing Health and Fitness with real-time monitoring and data storing like steps taken, calories burned, and miles walked.

The Nokia Lumia 630 is expected to rollout in May, beginning with Asia, Russia, China, India and Europe, from $159 for the single-sim variant, and $169 for the dual-sim variant. The Nokia Lumia 635 will be broadly available, including in the US starting in July, from $189.

Nokia also confirmed that Windows Phone 8.1 is scheduled to be available across the entire Lumia Windows Phone 8 portfolio as an over-the-air update this summer following testing and partner approvals.
