The display in question is a 5.0-inch, Super LCD3 with a resolution of 1920 x 1080, which gives it a pixel density of the astonishing 440 ppi. The display is quite big but at 143 x 71 x 9.1 mm, the J butterfly is only slightly bigger than the One X (134.4 x 69.9 x 8.9 mm) and at 140g weighs just 10g more.
Inside, the HTC J butterfly runs on a quad-core Qualcomm APQ8064 Snapdragon S4 processor clocked at 1.5GHz with 2GB of RAM. It has 16GB internal memory along with a microSD card slot.
