The Kyocera Echo might be one of the most unique phones in recent memory. The dual-display Android 2.2 handset on Sprint can do some interesting party tricks by running two applications on two screens at the same time. Simul-tasking is what Kyocera calls it. In our review, we gave the Echo a weak 2.5/5, because we felt that while the concept was interesting, the execution could have been better: the Echo isn’t exactly speedy, plus it is ugly, heavy, and has poor build quality.

It seems that we’re not the only ones that question whether the device is compelling enough to use everyday. When asked about sales of the Echo, a RadioShack saleswoman said “There hasn’t been much interest. We’ve sold four in a month, and all four were returned. People mostly don’t like the battery life.”

By our unscientific measures, the Echo isn’t the most popular device. But perhaps you, or someone you know, has purchased and Echo are really enjoying it. If that’s the case, drop us a comment and let us know how you’re getting along with your dual-screened Android!
