Question

Answer 1

As long as your Sensor Settings are On within Menu, Settings, Phone, Sensor Settings then you just need to do the following -
Tapping
The tap function allows you to quickly
mute and reject calls and alarm tones, and
to display a clock just by double-tapping
the back or front of the phone when the
slide is closed.
Select Menu > Settings > Phone >
Sensor settings to activate the tap
function and vibration feedback.
Mute calls or alarms
Double-tap the phone.
Reject a call or snooze an alarm after
muting it
Double-tap the phone again.
Display the clock
Double-tap the phone.
(If you have missed calls or received new
messages, you must view them before you
can see the clock.)
Simply, if you double tap the screen when the slide is closed and you can see the clock appear then it is working.
I hope this makes it clearer for you.
