A sequel to the HTC Butterfly, which was known in the U.S. as the HTC DROID DNA, a Verizon exclusive, has been rumored for some time. In April, a version of the HTC Butterfly 2 4G, headed for Japan, showed up on the AnTuTu site wearing a 5 inch display with resolution of 1080 x 1920. This model is powered by a quad-core 2.5GHz Snapdragon 801 with 2GB of RAM and 16GB of native storage. A 13MP snapper is on back with a 5MP front-facing camera.
The NCC certification indicates that the device could launch soon. But we don't expect to see this model outside Asia. The manufacturer still has the HTC One (M8) as its flagship handset, and with the HTC One (M8) Prime having been scrapped, it will remain up to the former to battle the Samsung Galaxy S5 and LG G3 for the top spot among Android top sellers this summer.
Thanks for the tip!
