Could these be the specs of the Sony Xperia Z4?

Rumoured specifications for the Sony Xperia Z4 have found their way onto the web.

If the latest rumours surrounding the specifications for the highly anticipated Sony Xperia Z4 prove to be true then we could see a significantly better smartphone than its predecessor.

There hasn't been any official word from Sony yet regarding the release or announcement of their flagship smartphone, but reports online suggest that the Japanese tech giant may be gearing up for an unveiling at CES 2015 in Las Vegas in January.

If this predicted announcement date is true then we can't expect to see an increased number of specification and product picture leaks the closer we get to next year.

Early reports did claim that Sony were planning on upping the screen size in the Z4 to 5.5-inches, which would be .3 of an inch larger than that on the Z3. However a recent 5.2-inch digitiser leak purporting to be from the Z4 does suggest otherwise.

The recent digitiser leak also suggests that the speakers will revert back to the Z2 design where they were inside small strips on the front panel's edges.

What is consistent in many of the rumours is the claim that the Xperia Z4's display will have stunning Quad HD resolution of 2560 x 1440. Reports are especially confident in making this prediction considering it has become the norm for many of the Z4's smartphone rivals including the Samsung Galaxy Note 4 and the LG G3.

Other unofficial leaks claims that the Z4 will be a bit of a smartphone powerhouse sporting a 2.8GHz Snapdragon 810 64-bit quad-core processor under the hood, accompanied by a huge 4GB of RAM. Why anyone would need as much RAM in a smartphone as you get in your average laptop these days isn't quite clear.

Also expect to see Bluetooth 4.1 on the device and a boost to the camera with reports claiming the Z4 will feature a 21MP Exmor RS CMOS lens.
