@esthreel - I know your pain of the alarm not turning off! What's more annoying is when the phone rings, you take it out of your pocket and the screen just does not turn on... and then when it does it takes about 5 seconds before the phone registers you pushing the answer button.

Try this as well:

1. click onto a blank space in the desktop and then on the 'cog' to go into desktop edit mode.
2. push the power button once and click on secure device

Even though the device is locked the top menu still stays and you can click on it (although admittedly I can't see to get around the lock... yet)
