The HTC Butterfly is a high-end phone by the HTC Corporation. The phone has been quite popular all over the world; however, most people don’t know exactly how popular the phone has actually been. This is mainly because not many people know that the HTC Butterfly and HTC Droid DNA is actually pretty much the same phone, with only a few differences. The differences are only there to make the phone more regional specific.

The HTC Butterfly is sold in four variants: Droid DNA in the United States on the Verizob Network; J Butterfly HTL21 in Japan on KDDI's au network; Butterfly X920d in Taiwan, South East Asia and India; and Butterfly X920e in China and Russia.

The HTC Droid DNA differs from the other variants, in that it supports wireless charging, but lacks a MicroSD slot. The Droid DNA and the J Butterfly both support CDMA and LTE connections, as well as UMTS. However, only the Droid DNA comes with quad band UMTS radio. The X920d and X920e, on the other hand, do not even have LTE support. There are also some subtle differences regarding color accents, buttons and logo placement. However, these are minor and so not affect the phones.
