11. Hold your phone straight up
Hold your mobile phone straight up, as
you would a regular phone. The LG-E405f
has an internal antenna. Be careful not to
scratch or damage the back of the phone, as
that causes loss of performance.
While 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.
12. When the screen freezes
If the screen freezes or the phone does not
respond when you try to operate it:
Remove the battery, reinsert it, then turn the
phone on. If it still does not work, please
contact the service centre.
13. Do not connect your phone
when you turn on/off your
PC.
Make sure you disconnect the data cable
between your phone and PC; leaving it
connected might cause errors on your PC.
