Sony Xperia Z5 Ultra rumored to come in March 2016 with Snapdragon 820 on board

According to a recent rumor, the Sony Xperia Z5 Premium, the world’s first smartphone with a 4K display, is not the only ultra high-res smartphone that Sony is preparing. Although when Sony unveiled the Z5 Premium this past week at IFA 2015 in Berlin, many thought that this is the handset that was previously referred to Xperia Z5 Ultra, a new rumor suggests that Sony did not give up on releasing a large-screened phablet under the “Ultra” moniker.
