Troubleshooting
Q: What is my password for the lock,
PIN, or PUK codes?
A: The default lock code is 12345. If you
forget the lock code, contact your device
dealer. If you forget a PIN or PUK code, or
if you have not received such a code,
contact your network service provider.
For information about passwords, contact
your access point provider, for example, a
commercial internet service provider (ISP)
or network service provider.
Q: How do I close an application that is
not responding?
A: Select Options > Show open apps. ,
and go to the application using the menu
key. Press and hold the menu key to open
the application, and select Options >
Exit .
Q: Why do images look smudgy?
A: Ensure that the camera lens protection
windows are clean.
Q: Why do missing, discolored, or
bright dots appear on the screen every
time I switch on my device?
A: This is a characteristic of this type of
display. Some displays may contain pixels
or dots that remain on or off. This is
normal, not a fault.
Q: Why can't my Nokia device establish
a GPS connection?
A: Establishing a GPS connection may take
from a couple of seconds to several
minutes. Establishing a GPS connection in
a vehicle may take longer. If you are
indoors, go outdoors to receive a better
signal. If you are outdoors, move to a
more open space. Ensure that your hand
does not cover the GPS antenna of your
device. If the weather conditions are bad,
the signal strength may be affected. Some
vehicles have tinted (athermic) windows,
which may block the satellite signals.
Q: Why can’t I find my friend’s device
while using Bluetooth connectivity?
A: Check that both devices are compatible,
have activated Bluetooth connectivity,
and are not in hidden mode. Check also
that the distance between the two devices
is not over 10 meters (33 feet) and that
there are no walls or other obstructions
between the devices.
