Upcoming Nokia phones 2014: In the last few weeks, there have been rumors circling the Web that there will be more Lumias during Microsoft's BUILD Conference on April 2. Today, one of those rumored Lumias has appeared in a demo clip ahead of its supposed announcement day on Wednesday. 

According to a report by GSM Arena, the Nokia Lumia 630 has recently been leaked in a demo video, and while it does not boast impressive high-end specs, it is still interesting because of Microsoft's new Windows Phone version. 

In the video, there isn't much to show about the Lumia 630's hardware specs aside from the 4.5-inch screen that you see all throughout the clip. On the other hand, there are a number of notable changes in the UI, thanks to Windows Phone 8.1.

Also known as Cherry Pink Blossom, the 8.1 update provides a number of new features to upcoming Nokia phones, such as the Lumia 630. 

Now, there are Wi-Fi, brightness level and Bluetooth toggles in the quick settings menu, just like in Android. You can even access the camera straightway through this window. 

Speaking of windows, the tiled homescreen in the Lumia 630 has a changeable background, thanks to Windows Phone 8.1.

In case rumors are true, here are other specs of the upcoming device: Snapdragon 400 chipset, 1GB RAM, 5MP camera with no flash, dual-SIM (the first ever for WP platform), and of course Windows Phone 8.1 a.k.a. Cherry Pink Blossom. 

Here are the two videos which showcase the Lumia 630.
