The Japanese manufacturer has been teasing some of its upcoming Sony phones in 2014 for the past few months, and it looks like it's  working.  

If you are looking for the best Android phones in the market right or in the next couple of months, you better watch out for the Sony Sirius. 

Leaked several times already, the upcoming Sony handset is set to become a beast in terms of processing speed. It is rumored to boast a quad-core chipset, Snapdragon 800, 2GB of RAM and the camera lens Sony has been known for. 

Other rumors say the Sony Sirius is actually the Xperia Z2 in disguise. But even before Sony makes anything official, an alleged video of the device's UI has surfaced on the Internet. 

From the video, we can see the homescreen transitions in the phone, Android 4.4 Kitkat, and Sony's version of an mobile operating system skin. 

Sony has been releasing high quality phones in the past few months so we would expect nothing but the best from the Japanese tech giant, especially now that it is officially expanding its range in the US market. 

Here's the alleged UI video.
