The HTC J Butterfly has surfaced on HTC’s Japanese website and it is that elusive 1080p 5-inch monsterphone we’ve been hearing about all along. The 5-inch Super LCD 3 display on the HTC J Butterfly works out at 440ppi, a truly amazingly detailed resolution. It’s also very thin at just 9.1mm which makes it easier to deal with such a big display. The Butterfly has all you’d expect from such a device: a quad-core 1.5GHz Snapdragon S4 Pro APQ8064 processor, 2GB of RAM, and an 8-megapixel rear camera. It also runs on Android 4.1 Jelly Bean.
