Lock and unlock your screen
Your phone allows you to quickly turn the screen off when not in use and to turn it back on and
unlock it when you need it.
Turn the screen off when not in use
To quickly turn the screen off, press the Power key. Pressing the Power key again or receiving
an incoming call will turn on your phone screen and show the lock screen.
To save battery power, the phone automatically turns off the screen after a certain period of
time when you leave it idle. You will still be able to receive messages and calls while the
phone’s screen is off.
Note: For information on how to adjust the time before the screen turns off, see Display
settings.

password or PIN. See Screen lock for details.
Update your phone
From time to time, updates may become available for your phone. You can download and apply
updates through the Settings > System > System updates menu.
Software update cautions
Update Size: Any update larger than 100MB will require you to connect to Wi-Fi as the
update cannot be downloaded over the cellular network.
During update: The phone cannot be used until the software update is complete. It may
take time to update your phone’s software.
Signal during update: Update your phone where signal reception is good, and do not
change location during the update process. Make sure the battery is adequately charged
before beginning an update. A weak signal or low battery during an update may cause the
update to fail. An update failure may disable the phone.
