Nokia has officially announced the Nokia Lumia 928, a new Windows Phone that will be exclusive to the Verizon network in the US.Much of the focus of the new handset is on the camera, carrying the PureView branding and offering a Carl Zeiss f\/2.0 wide angle lens. There's a 8.7-megapixel sensor, supported by optical image stabilisation, promising great quality photos whatever the situation.\u00a0Even though the Lumia 920 was impressive, the 928 takes photography a step further with the introduction of a Xenon flash, making this the only current smartphone to offer the same type of flash as a compact camera. We would expect this to enhance indoor snapping further.\u00a0Nokia has also made pains to emphasise the quality of the audio capture in video, claiming that the Lumia 928 will give you distortion-free capture, as well as impressively loud playback.\u00a0None of this comes as a surprise, as Nokia has been progressively revealing this information through its own website.Completing the picture there's a 4.5-inch OLED display, packing in Nokia's tech that will let it work even when you're wearing gloves. It offers a resolution of 1280 x 768 with a 15:9 aspect and a pixel density of 334ppi.\u00a0Sitting at the heart of the Nokia Lumia 928 is a 1.5GHz Qualcomm dual-core chipset, backed by 1GB RAM. There's 32GB of internal memory and you get the standard 7GB SkyDrive storage. There's no mention of expansion via microSD.The handset is powered by a 2000mAh battery, which we hope the Xenon flash won't have too much of an impact on."Verizon Wireless customers, we heard you and the wait is over - we're excited to offer a Nokia flagship smartphone, specially designed and optimised for the nation's largest 4G LTE network," said Matt Rothschild, vice-president, Nokia North America.This handset will sit on Verizon's 4G network and will be available from 16 May, in black or white, for $99 (\u00a365) after a $50 mail-in rebate on a new two-year contract.The news comes as a slight surprise, as we're awaiting Nokia's announcement for the 14 May, which we can now surmise will be the Lumia 925, a global variant of this handset. Of course, we'll bring you all the details when we have them.
