22. 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: Press and hold the menu key, select Options > Show open apps., and navigate to
the application with the menu key. Press and hold the menu key, and select 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.
Q: Why can’t I end a Bluetooth connection?
A: If another device is connected to your device, you can end the connection from the
other device or deactivate Bluetooth connectivity in your device. Select Menu >
Settings and Connectivity > Bluetooth > Bluetooth > Off.
Q: Why can't I see a wireless LAN (WLAN) access point even though I
know I'm within its range?
A: The WLAN access point may use a hidden service set identifier (SSID). You can only
access networks that use a hidden SSID if you know the correct SSID, and have created
a WLAN internet access point for the network on your Nokia device.
