Lock or unlock your phone
LOCK YOUR PHONE
If you want to avoid accidentally making a call when your phone is in your pocket or 
bag, you can lock your keys and screen.
To lock your keys and screen, press the power key.
UNLOCK THE KEYS AND SCREEN
Press the power key, and swipe up across the screen. If asked, provide additional 
credentials.
Use the touch screen
Important: Avoid scratching the touch screen. Never use an actual pen, pencil, or 
other sharp object on the touch screen.
YOUR PHONE DISPLAY
Leaving the phone screen on with maximum brightness level for a long time may 
cause the display image to remain on the screen even when the screen switches off 
or when a new image appears on the screen. 
To avoid this:
- Lock your screen when you’re not using the phone and set the phone screen to 
switch off after a short time. Tap Settings > Display > Advanced > Sleep and 
select the time.
- Keep your phone up to date and accept available software updates 
- Lower the screen brightness: tap Settings > Display > Advanced > Brightness 
level.  To adjust the brightness, drag the brightness level slider. Make sure that 
Adaptive brightness is disabled.
