Nokia Lumia 630 specs leaked ahead of rumoured Build 2014 launch

News has been coming in dribs and drabs about the rumoured Nokia Lumia 630, but now more information has been released regarding the upcoming entry-level phone, including a list of specifications.

The device is expected to be released in China in April this year (following Microsoft's Build conference) with a price of around $150 (£90 at current rates). Images of the phone have already been released, revealing a colourful backside but a camera without flash or camera key.

The new details have been leaked by Chinese blog Winp.cn, revealing the phone to have a 4.5in, 854 x 480 screen, Qualcomm Snapdragon 400 quad-core processor with 1GB RAM, GSM + WCDMA network support and a dual-SIM slot.

As supposed by previous leaks, the Lumia 630 will also feature virtual navigation and the phone is tipped to measure 129.5 x 66.7mm in terms of height and width.

The device will come with Windows Phone 8.1 directly out of the box. The leaked specs appear to confirm, too, that the camera on the Lumia 630 will not feature a dedicated action key on the handset's frame, or come with flash capabilities.

Windows Phone 8.1 should get a release later this year with a host of new features including Siri-like personal assistant Cortana. Nokia is expected to reveal the Lumia 630 at Build 2014 in the near future.
