How can I enable the hardware lock button on the Xda?
You can enable the hardware lock button on the Xda by tapping Start>Phone>Tools>Options>More then tap ‘Lock all buttons except Power button’. This will disable all button presses when the device is switched off. Or you can also set a password for extra security (either 4 digit or alpha/numeric) – so if you tap the screen when it’s in standby mode, you are first prompted for your password. This will stop any accidental screen taps from progressing further (if it was in your pocket for instance).
