While we may only have recently seen the latest Sony flagship, the Xperia Z3, rumour has it that the tech giant is busy working on its next device, the Xperia Z4, which is due for release in 2015.

So, what do we know so far?

Release date

As all of this is so far speculation, we can try and work from what we know of Sony’s previous releases. The original Xperia Z was released in February 2013, with Xperia Z2 following suit little over a year later in March 2014. The latest release was obviously just in Autumn this year, perhaps due to the fact that Sony had said they wanted to beat the yearly cycle most companies have.

While there is no clear pattern to follow, there have been murmurings that point to the Xperia Z4 being Samsung’s only flagship device released next year, perhaps coinciding with the 2015 Mobile World Congress, which will be taking place in Barcelona in March. If it isn’t confirmed during the event, it will hopefully be released in April.


It is more than likely that the Android 5.0 Lollipop will be up and implemented within any 2015 device and as Sony confirmed that they will be using the update for a number of their products, it is looking likely that this is what we can expect.


Rumour has it that the device will be powered by the Qualcomm Snapdragon 810 octa-core 64-bit chipset at 2.8GHz, as well as the new Adreno 430 GPU.

Storage-wise, we have our fingers crossed that the usual 16GB internal storage will be upgraded to 32GB, with RAM supposedly going to be 4GB.

The Xperia Z4 will also apparently be the first within its family to come with LTE Cat.6 connectivity and Bluetooth 4.1.

Anyone worried about the camera can rest assured as that will also apparently be upgraded from the IMX220 20.7MP sensor to a curved Exmore RS CMOS sensor.

Again, it must be reiterated that all of this is rumour and nothing has yet been confirmed.
