We’ve been hearing about a certain 5-inch HTC phablet for Verizon since July, but it looks like its Japanese counterpart may actually hit the market first. Unveiled by KDDI as the HTC J Butterfly (HTL21), this Android 4.1 device is the first announced phone to feature a 5-inch, 440ppi full-HD “Super LCD 3″ panel, and it’s fittingly complemented by a 1.5GHz quad-core APQ8064 underneath, making this the latest member in the small family of Snapdragon S4 Pro phones. There’s an eight-megapixel camera that naturally handles 1080p video at the back, accompanied by a 2.1-megapixel front-facing imager. Other details include 2GB RAM, 16GB internal storage, microSDHC expansion, 802.11a/b/g/n WiFi, Bluetooth 4.0 (LE), NFC, LTE and CDMA/GSM/UMTS/GPRS radios — that’s right, it’s a global device. Not bad for a 140g package, and it’s waterproof as well, rated at IPX5. But the question is how well will the 2,020mAh battery last under that super dense LCD and high-end processor? Only time will tell — even KDDI has yet to finalize this part of the specs. Folks on the KDDI network can grab hold of this powerful phone in early December, with a choice of red, white or black.
