First, we had the HTC J-Butterfly. Next, came the Verizon Droid DNA. Now, what we appear to have is the same phone, with a slightly different name heading for other markets. The Butterfly has appeared on HTC's website with little else to indicate on where or when it may be available.
The good news if you're in China -- it's heading your way. An HTC spokesperson has confirmed to Android Central that at present the Butterfly is slated for release in China, and that there is no information relating to availability in other markets at this time.
Looking through the spec sheet, there are a couple of differences between the Butterfly and the Droid DNA. For one, there's no LTE. The other difference that stands out is the expandable storage. The Butterfly carries the same 16GB of on board storage as the DNA, but is expandable by way of microSD cards. It still runs Android 4.1 Jelly Bean and Sense 4+ out of the box, and houses the same 2020mAh battery. Oh, and of course, that 5-inch, 1080p display.
