According to new rumors Sony is incorporating new tech in its upcoming Phablet which will allow it to use any pen or pencil as input device. Other umored specs of the Sony Xperia Z Ultra include a 6.44" 1080p display, Qualcomm Snapdragon 800 chipset, 2GB of RAM, 16GB of expandable storage, and an 8MP main camera. The phablet is expected to boot Android 4.2 Jelly Bean at launch.
Like the Sony Xperia Z, the upcoming phablet is rumored to be water resistant. The display will reportedly support input from a stylus or a pencil - the hand written note on the invitation also suggests that the feature will be present.
