4K UltraHD video is expected to come to Android this year
At CES and MWC, Qualcomm showed off the 4K UltraHD recording capabilities of its Qualcomm Snapdragon 800 chip and has previously stated that it would be "in commercial devices" by the middle of 2013. For those unaware, 4K UltraHD video offers resolution four times the 1080p that is considered a Full HD display. That works out to 4096 x 2304.
So you might as well pick another one of the alleged specs belonging to the LG Megalotron to call the whole thing a fake, because we could very well see 4K UltraHD video sometime later this year.
