Hold Your Phone Upright - LG Optimus L4 II Guide De L'utilisateur

Important notice

8. Hold your phone upright

Hold your cell phone vertically, as you would a regular phone. Your phone has an
internal antenna. Be careful not to scratch or damage the back of the phone, as this
may affect performance.
When making/receiving calls or sending/receiving data, avoid holding the lower part of
the phone where the antenna is located. Doing so may affect call quality.
9. When the screen freezes
If the screen freezes or the phone does not respond when you try to operate it:
Press and hold the Power/Lock key for 10 seconds to turn your phone off.
If it still does not work, please contact the service center.
