According to DisplaySearch, the iPhone 6 will have a 5.5-inch 1,920×1,080 display. If Apple releases a 5.5″ iPhone, then yes that is a phablet. I’m hoping they use IGZO screens, and for the screen size to be at least 4.7″ , preferably 5″-5.2″.
After Apple releases a 5.5″ phone then what? Samsung will be on it’s 2nd generation bendable phone/tablet hybrid while Apple is still pushing “s” models. Apple is so predictable it’s sad to even think that the iPhone was a desirable phone in its history. Apple lacks innovation and only thinks about maximum profits with old ideas.
