Although Sony recently announced the Xperia Z at CES, rumor has it Sony is working on a new smartphone with a 6.44-inch display and 1080P resolution. This 6.44-inch display will place this phone closer to the new “phablet” category. It’s possible Sony could reveal the new phone at MWC happening next month, or sources are saying it might be a prototype, or even fake. Once we know more information about this new phone we’ll be sure to post it.
