9. Unlock screen when using a data
connection
The LCD display will go dark if untouched for a set time
when using a data connection. Touch it to turn it on
again.
10. Do not connect your phone when
you turn your PC on and off
Make sure you disconnect your phone and PC via a data
cable to avoid any harm to your PC.
11. Hold your phone upright
Please hold your phone straight and level, like a normal
phone. The Optimus 3D has an internal antenna. Be
careful not to scratch or damage the back of the phone,
as this will impair performance. While making/receiving
calls or sending/receiving data, try to avoid holding the
lower part of the phone where the antenna is located.
This may affect call quality.
12. If the screen freezes
If the phone does not respond to user input, or the
screen freezes:
Remove the battery, reinsert it and switch on the phone.
If it still does not work, please contact the service centre.
