Sony Xperia Z2 may make MWC 2014 appearance according to @evleaks.
The phone is currently known as the Sony Sirius and has a 5.2-inch display with a Qualcomm Snapdragon MSM8974AB SoC chipset.
Earlier rumours suggested that it would have a 1080p full HD display with 506ppi, a quad-core Snapdragon 800 processor, 3GB of RAM, Android 4.4 and a 20.7MP camera with a xenon flash.
No word on whether optical image stabilisation is on board. This would be a killer feature.
