The Sony Xperia D6503 Sirius is widely expected to debut later this month as the Sony Xperia Z2, and the smartphone now stars in a new video.

Sony's follow-up to the popular Xperia Z1 has leaked on several occasions so far, and although nothing is official at this point, various reports have tried to paint a picture of what to expect.

Codenamed Sirius, the purported Sony Xperia Z2 has already appeared in several photos and a short video recently, and now a new video aims to give us a more detailed look.

Just last week, a YouTube user called Rimas Flyil leaked a video allegedly showing the Sony Xperia Z2. The latest leaked video now comes from the same source, but gives a longer look at the purported device.

The Sony Xperia Z2 is expected to boast high-end specs and features and bring notable improvements compared to its predecessor. The handset will reportedly rock the very latest version of Google's popular operating system, i.e. Android 4.4 KitKat.

In terms of specifications, the Sony Xperia Z2, or Sirius, is expected to sport a 5.2-inch full HD display with a resolution of 1920 x 1080 pixels, pack a powerful Qualcomm Snapdragon 800 quad-core processor and a hefty 3GB of RAM. The handset will reportedly come with 32GB of internal storage capacity and feature Sony's flagship mobile camera, the 20.7-megapixel Sony Exmor RS. The smartphone will likely have a 2.1-megapixel front camera as well.

The upcoming Sony Xperia Z2 is also expected to be water- and dust-resistant, just like most of Sony's recent offerings. The company has yet to officially disclose its plans for the Xperia Z1 successor, but it will likely not be too long before it becomes official.

With the Mobile World Congress (MWC) 2014 kicking off later this month, on Feb. 24, in Barcelona, we should hear more about the Sony Xperia Z2 soon enough. It is highly advisable to take all leaks and rumors with a grain of salt until official confirmation, including this video. That said, you can watch the latest leaked video below to see the purported Sony Xperia Z2 in action.
