A new set of screenshots related to Sony's upcoming Xperia Z Ultra phablet have been leaked online, confirming its specifications.

The XDA-developers have posted the purported screenshots of the Xperia Z Ultra smartphone ahead of its speculated launch on 4 July. Snapshots of the smartphone, which has long been rumoured for release, have hit the internet quite a number of times in the past. The new set of images indicated that the device will sport a large 6.21-inch screen with 1080p resolution with 320PPI screen, contrary to earlier reports which suggested that it will have a bigger 6.44-inch Triluminos.

Other specifications include a 2.3GHz quad-core Qualcomm Snapdragon 800 chipset along with Adreno 330 GPU, Android - 4.2.2 Jelly Bean operating system, 2GB of RAM and 16GB of internal storage with an optional microSD card. Details of its image snapper are yet to be confirmed. According to earlier reports, the smartphone is expected to pack an 8-megapixel rear camera and a 2.2-megapixel camera on the front. It was also rumoured to be water resistant like the Xperia Z smartphone and would be compatible even with a pencil.

Last week, Sony has sent invites to the media fraternities for an event on 4 July and the smartphone, giving rise to speculations that the smartphone will make its debut. The invite showed an image of a slim device with power/lock key, volume rocker and a stylus. The design language of the smartphone seemed to be the same as that of Xperia Z. The device was initially expected to be unveiled on 25 June.
