It seems like no smartphone vendors can manage to keep their upcoming handsets under wraps these days, but BlackBerry always has more trouble than most keeping its unreleased devices a secret. BGR exclusively posted the first-ever photo of BlackBerry’s upcoming Z30 phablet last month, though it was thought to be called the A10 at that time. Several photos and videos have leaked since then, and now the Z30 stars in a full hands-on video walkthrough published by Vietnamese site Cellphone S. The BlackBerry Z30 is expected to feature a 1.7GHz dual-core Qualcomm MSM8960 processor, a 5-inch AMOLED display, an 8-megapixel rear camera, a 2-megapixel front camera, 2GB of RAM, 16GB of internal storage and a 2,800 mAh battery. The full hands-on video follows below.
