Hi, I was going to buy the Sony XPeria Z Ultra from a store last night when the salesman gave me a demo and I noticed a midly unnerving feature of the Sketch app in the device. Unlike the Samsung Galaxy Note 10.1 where the S Note screen rotates upon rotation of the screen and lets me take notes in both portrait and landscape modes, the Sketch app in the Sony XPeria Z Ultra doesn't seem to let me do that. Is this a software glitch which could be fixed by an update, or is it a hardware limitation? Thanks in advance! PS -- I couldn't find a sub-forum here for the Xperia Z Ultra. But to be sure, I am referring to the C6802 model.
