To lock the phone

Locking the phone turns off its functionality. This is a helpful feature if, for example, the phone is turned on and in your pocket, and you want to prevent accidental keypresses. Once the phone is locked, the left SOFT KEY label changes to Unlock.

You can lock the phone by:

•Pressing and holding for about 2 seconds (must not be in a text box).

•Pressing and holding the HOME key to open the Quick list and then selecting Lock.

•If the Manual Lock option is enabled in Settings, you will be prompted to lock the phone when you close the keyboard.
