More information about the Nokia 630 has surfaced on the web. According to Sofica Camspeed, an online service that lets users test their phones’ camera speed, a user tested the rumored soon-to-be-released Lumia 630. That is not all, Sofica states that Lumia 630 was running the upcoming Windows Phone 8.1.
The test found the device running Windows Phone 8.1 (build 8.10.12324.0). Windows Phone 8.1 is the new version of Microsoft's mobile operating system, which is coming this spring. However, we have already seen its accidental listing on the Windows Phone website, and have played with its SDK. The upcoming Windows Phone OS bundles many new features, including support for "Universal Apps" and 3rd party message clients. You can read about all the features of Windows Phone 8.1 here.
The Lumia 630 is supposedly the successor of the Lumia 620. From the leaked specifications, the phone is tipped to have a 4.5-inch display with 845x480 resolution. The phone will be powered by a Qualcomm Snapdragon 400 Processor and will have a gig of RAM inside it. It is expected to come with dual SIM support.
