Sony's flagship Android smartphones Xperia Z and Xperia ZL images have been leaked days ahead of its CES launch.

There have been several speculations about Sony's flagship smartphones but the company had kept mum on the matter.

However, the images that appeared on Sony's website more or less confirmed the launch of Sony Xperia Z and Xperia ZL.

Earlier in December, it was reported that Sony's much-anticipated 5-inch HD display and 1080p high end device, the C660X Xperia Yuga, could also come with IP57 certification for dust and water resistance. The C660X Xperia Yuga will reportedly debut as Xperia Z, as the latter is considered more market-friendly title.

Rumours about Sony's upcoming smartphone have been rife for quite some time. According to the earlier leaked information, Xperia Z is likely to boast of a 5-inch display with 1080p resolution along with a compact slim body measuring 139 x 71 x 7.9mm. The device is expected to be powered by Qualcomm Snapdragon S4 Pro quad core processor and might use Android 4.1.1 Jelly Bean Operating System. Other rumoured features include 12Megapixel P/13MegaPixel rear camera with HD quality and 3GB of RAM.

Xperia Z might also get Sony's OptiContrast technology which is used to reduce the onscreen reflection of televisions. It would also pack 128GB of built-in memory and a battery of 3000 mAh along with a micro SD card slot.

On the other hand, it is rumoured that the Sony Xperia ZL would come with a 1GHz Qualcomm Snapdragon MSM7227A CPU along with an Adreno 200 GPU. It is expected to run on Android 4.0.4 Ice Cream Sandwich.
