Sony was the latest vendor to become the focus of the device rumour mill, with speculation about the new flagship the company is expected to unveil at Mobile World Congress.

The device is being referred to variously as Xperia Sirius and Xperia Z2.

According to Android Community, the device will feature the same 20.7 megapixel camera as its predecessor. However, it will support a number of new features, including 4K video capture and apps which support various imaging effects.

It will also enable 1080p video capture at 60 frames per second – double that of the Xperia Z1 – and gains a 15.5 megapixel still image resolution, alongside the existing 8 megapixels and 20.7 megapixels.

An earlier Android Community report also referred to “smart call handling” features, which enables calls to be answered, sent to voicemail, or ringtones silenced by moving the device. It is also said to feature an on-device voicemail feature.

Other features of the device are expected to include a 5.2-inch screen – falling into what would have been the phablet range not that long ago – and be powered by a Qualcomm Snapdragon 800 processor. It will have 3GB of RAM.

It is said to physically resemble the earlier Xperia Z1, but with a thinner body.
