Troubleshooting
If you encounter problems while using the phone, or if it performs abnormally,
you can refer to the chart below. If your particular problem cannot be
resolved using the information in the chart, contact the dealer where you
purchased the phone.
Problem Possible causes Possible solution
Poor reception The network signal is too weak at
your current location, for example, in
a basement or near a tall building,
because wireless transmissions
cannot effectively reach it.
Move to a location where the
network signal can be properly
received.
The network is busy at the current
time (for example, during peak times,
there may be too much network
trafc to handle additional calls).
Avoid using the phone at such
times, or try again after waiting
a short time.
You are too far away from a base
station for your service provider.
You can request a service area
map from your service provider.
Echo or noise Poor network link quality on the part
of your service provider.
End the call and dial again. You
may be switched to a better-
quality network link or phone
line.
Poor local telephone line quality. End the call and dial again. You
may be switched to a better-
quality network link or phone
line.
Unable to
select certain
features
Your service provider does not
support these features, or you have
not applied for services that provide
these features.
Contact your service provider.
Problem Possible causes Possible solution
Battery not
charging
The battery or battery charger is
damaged.
Contact the dealer.
The phone’s temperature is below 0°C
or higher than 45°C.
Adjust the environment to avoid
extremes of temperature.
Poor contact between the battery
and charger.
Check all connectors to make
sure all connections have been
properly made.
Shortened
standby time
The standby time is related to your
service provider system conguration.
The same phone used with different
service providers’ systems will not
provide exactly the same length of
standby time.
If you are located in an area
where signaling is weak,
temporarily power off the phone.
The battery is depleted. In high
temperature environments, battery life
will be shortened.
Use a new battery.
Battery power is consumed in a
variety of ways, including sending
out signals to locate a base station
when you are unable to connect to
a network.
Turn off Wi-Fi, GPS, and Bluetooth
if they are not being used. You
can also adjust your screen
brightness and timeout duration
in Settings > Display.
