If you've ever searched for the setting that controls the vibration of the capacitive touch buttons on the Dell Streak, then you know it doesn't exist. Haptic feedback can be disabled throughout the entire system very easily, yet for some reason the option isn't given for the capacitive controls. So your poor thumb always gets buzzed when it's doing nothing more than pressing the Back, Menu, or Home button.
Give the little guy a break and get Streak Vibrations, an app for rooted Streaks created by MoDaCo forum member JFDee that disables (and re-enables) all vibrations with a simple tap. Nice![MoDaCo]
