HTC's hidden tricks

Did you know you can set HTC smartphones to ring louder if they're in your pocket or purse? HTC phones offer a wealth of features it doesn't publicly brag about, but they're there. You can actually shut off a phone's ringer by flipping it on its face, or engage the speakerphone by flipping it back up. Pictured: HTC CEO Peter Chou holding up the Desire Z and Desire HD.
