Walkthrough video of BlackBerry Z30 spotted online

Last week photos of BlackBerry's next flagship device the Z30 were leaked online by CrackBerry.com. Now a full-fledged video has come up, which shows a walk-through of the upcoming BlackBerry device.The video has been put up by a Vietnamese publication, Cellphone S and since the video is in Vietnamese, it is difficult to know what it talks about. In the video, however one can see the AT&T logo on the rear panel of the device.While it is hard to verify if this is indeed the new Z30 or just the old Z10, the phone's screen does look a little bigger than the current BlackBerry Z10.[caption id="attachment_1027329" align="alignleft" width="380"] BlackBerry Z30 in this screengrab from YouTube video.[/caption]According to rumours, the BlackBerry Z30 will come with a 5-inch AMOLED display with 720x1280 pixels screen resolution and pixel density of 295 ppi.Other features include: 1.7GHz dual-core Qualcomm MSM8960 processor, 2GB of RAM and Adreno graphics processor.The camera is expected to have a 8-megapixel camera at the back and a 2 megapixel front camera.
