I have an HTC SNAP S511 cell phone. The keypad keys are useless, even though the phone has been used much less frequently than typical for a cell phone. Click repeatedly on many of the keys and nothing enters, then sometimes bairly touch one and it will enter charactors multiple times. Dialing and generating text messages can be a major challenge. The keys worked poorly intermittently from the time the phone was only a couple of months old. This phone is a piece of useless junk. It isn't difficult to design keypads that are reliable. I feel that HTC wants the phone to not work well so you'll need to get another (and keep buying new phones over and over). Guess what - I'll never own another of anything that says HTC on it.
