Japanese carrier KDDI has just announced a new HTC J Butterfly, a handset which resembles the HTC One in specs, but with features aimed at KDDI's home market. Like a lot of other Japanese devices, the 5-inch, full HD handset is waterproof in case you feel like taking fish photos. And to do so, the latest from HTC has brand new cameras: a 13-megapixel rear dual-camera model with a selfie-friendly 5-megapixel front shooter. That differs from the One M8's 4-megapixel Duo "Ultrapixel" camera. KDDI instead calls it a "Duo Effect" camera, with the secondary 2-megapixel module giving depth-of-field adjustment and other features. Filling out the spec sheet are a Snapdragon 801, 802.11ac WiFi, LTE-Advanced, 150Mbps 4g, 2GB of RAM, Android 4.4 KitKat, JBL audio profile (plus bundled earphones) and a Dot View case. All of that sounds pretty nice, but will it come to US shores? Hard to say, but the last J Butterfly model did eventually arrive as the Droid DNA (to Verizon), so we wouldn't be surprised to see the new model here too.
