The Butterfly S is not made of metal in the same way that the One is. Instead, it uses polycarbonates to form the outer shell. The shell houses a 5-inch 1080p HD Super LCD 3 display. It has an eye-popping 441 pixels per inch and is coated with an optical lamination that makes it easier to see outside under the sun. The display is also scratch resistant thanks to Gorilla Glass 3.
The Butterfly S is powered by a Qualcomm Snapdragon 600 processor with four cores running at 1.9 GHz. It is paired with 2 GB of RAM and 16 GB of storage. The Snapdragon 600 is one of the fastest processors available. It comes with a bevy of other radios, including GPS/GLONASS, NFC, Bluetooth 4.0 and 802.11a/b/g/n/ac Wi-Fi.
Like the One, the Butterfly includes an ultrapixel camera, which has larger individual pixels for better low-light performance. It uses back-side illumination and an f/2 aperture, and it's powered by HTC's dedicated ImageChip. The camera has five different levels of flash, with intensities that vary based on the distance between the subject and the phone. The user-facing camera rates 2.1-megapixels and has a wide-angle lens with HDR video capture. HTC also ported the One's Zoe feature to the Butterfly S, which captures short bursts of video and images to create "moments." It can also capture slow-motion video.

The device is a media powerhouse. It can play back full HD video on the display, or send it to an HDTV using Miracast, DLNA or an HDMI cable. It also includes an IR blaster and can act as a remote control for home theater equipment, such as TVs, cable boxes, receivers and DVD players. The Butterfly S also features HTC's BoomSound, which is enhanced sound that comes from two speakers on the front of the phone, and Beats Audio.
In terms of software, it is running Android 4.2 Jelly Bean and includes the newest version of HTC's Sense user interface overlay. Sense comes with BlinkFeed, which is HTC's social newsreader. BlinkFeed pulls in Facebook and Twitter posts, as well as news and headlines and creates a digital magazine on the home screen.
The phone is kept running thanks to a large 3,200-mAh battery.
HTC did not sell the Butterfly J in the U.S. Instead, it brought a variant of the phone called the Droid DNA to Verizon's network last fall. There's no word yet if or when HTC will offer the Butterfly S to U.S. buyers.
