Troubleshooting

Troubleshooting
• The smartphone does not start.
- Make sure that the battery is properly installed and
charged.
- Make sure that the contacts on the battery are clean.
- Try to switch on the smartphone by pressing the
power key for several seconds.
- Remove the battery, wait for at least ten seconds, and
replace the battery.
• The screen or phone keys flash when I try to charge
the battery.
- Make sure that the battery is properly installed.
• The battery does not recharge properly.
- Make sure that the connector is firmly in place and
the power outlet that you are using is working.
- Your battery may be at the end of its life cycle or
faulty. Contact your local Nokia dealer.
- While charging, do not use features such as Web
browser or RealOne player, which consume a lot of
power. Too many power-consuming activities may
prevent the battery from charging properly.
• Missing, discoloured, or bright dots appear on the
screen every time I turn on the smartphone.
- This is normal characteristic of this type of screen.
• The touch screen feels inaccurate.
- Calibrate the screen. Use the scroll key to open the
Control Panel application, select
follow the instructions.
• The smartphone stops responding to some or all
commands.
- Wait for a while. Some processes may take long to
complete. If the device still does not respond, an
application may be taking up too much memory. Press
for at least 5 seconds to close all applications
except the currently used one. If this does not help,
switch off the smartphone, and switch it back on. If
there is still no response, switch the phone off, remove
the battery, wait for at least ten seconds, and replace
the battery. To avoid problems with Web animations,
disable plug-ins: In the Web browser, press
select Tools > Settings.... Open the Plugins page, and
clear the Enable plug-ins check box. Disabling plug-ins
restricts the functionality of your Web browser.
• The applications and power key do not respond.
- Remove the battery, wait for at least ten seconds and
replace the battery.
- Try charging the smartphone.
If the procedures described above do not help, as a last
resort before contacting your local dealer you can try
formatting the internal memory of the smartphone.
