1. On the Home screen, touch > Apps tab > Settings > Storage.
2. Touch Unmount SD card and touch OK to confirm it.
3. Touch Erase SD card and then Erase SD card one more time to
confirm your choice.
4. If you have set a pattern lock, enter the pattern lock and touch Erase
Everything.
NOTE: If there is content on your memory card, the folder structure may be
different after formatting as all the files will be deleted.
Locking and unlocking the screen
If you do not use the phone for a while, the screen is turned off and locked
automatically. This helps to prevent accidental touches and saves battery
power.
When you are not using the LG OPTIMUS
SHOWTIME
™, press the Power/Lock
Key to lock your phone.
If there are any programs running when you set lock screen, they may be
still running in Lock mode. It is recommended that you exit all programs
before entering Lock mode to avoid unnecessary charges (e.g. phone calls,
web access and data communications).
