If this really is the Xperia Z4, we're disappointed ~ lotfi

Excitement has been growing for Sony's upcoming flagship smartphone, the Xperia Z4, however a new image has leaked onto the internet that claims to show what the Z4 will look like; and if it's real we can't help buy feel our excitement deflate a tad.

The photo comes from the Sony Georgia Facebook page and claims to be a real image that will be sent to the press. We're going to be taking a big pinch of salt with this, as there are a number of things that make us think (or hope) that this isn't what the final Xperia Z4 will look like.

It's not that the device pictured is ugly, but it's just so uninspired. The photo shows that Sony's rectangular omni-balance design that we've seen many times in previous Xperia devices has been retained – but that's part of the problem.

This image could be of almost any previous Xperia device and you wouldn't really notice.

Not so sweet design

Sony Xperia Z4 Another detail that has got us doubting the authenticity of this image is that the screen is displaying what looks like Android 4.4 KitKat running Sony's custom interface. We find it hard to belive that any company would release its flagship smartphone in 2015 without the latest version of Google's mobile OS, Android 5.0 Lollipop.

The rather boring design and older version of Android means we can't shake the feeling that we're looking at a mid-range smarphone here, rather than a top-of-the-range flagship model.

It's no secret that Sony's mobile division is in trouble, so it needs to release a flagship Xperia Z4 that really wows us and puts the competition to shame.

We reached out to Sony for comment on the authenticity of the image, but were told that "we do not comment on rumour or speculation".

If this really is what Sony has planned for the Z4, we're not just disappointed. We're worried.
