Troubleshooting for Nokia N8-00

Many features in your Nokia N8 device increase the demand on battery power and reduce the battery life time. To save battery power, note the following:

1. Always charge the battery fully (until the battery full notification is seen or the battery status bar stops running and stays in full position and charging indicator light is off).
2. Activate power saving mode. Press the power key, and select Activate power saving.
3. Change the synchronisation frequency for your mailbox. Select Menu > (Applications) > Mail, your mailbox, and  Options > Settings, and the relevant sync frequency settings.
4. Mute unnecessary tones, such as key tones.
5. Use wired headphones, rather than the loudspeaker.
6. Deactivate the background animation effects. Select Menu > Settings >Themes > General > Options > Theme effects > Off.
7. Deactivate the Big clock screen saver. Select Menu > Settings > Themes > Screen saver > None.
8. Features that use Bluetooth technology, or allowing such features to run in the background while using other features, increase the demand on battery power. To prolong the operating time of your device, turn the Bluetooth technology off when you do not need it (Menu > Settings > Connectivity > Bluetooth > Bluetooth = Off).
9. Features that use wireless LAN (WLAN, Wi-Fi) increase the demand on battery power. WLAN on your Nokia device switches off when you are not trying to connect, not connected to another access point, or not scanning for available networks. To further reduce battery consumption, you can in Symbian Anna and earlier specify that your device does not scan, or scans less often, for available networks in the background. WLAN switches off in between background scans. When Menu > Settings > Connectivity > WLAN > Options > Settings > Show WLAN availability is set to Never, the WLAN availability icon is not shown in the standby mode. However, you can still manually scan for available WLAN networks and connect to WLAN networks as usual.
10. If you have set Packet data connection (or Mobile data connection) to When available in connection settings, and there is no packet data coverage (GPRS), the device periodically tries to establish a packet data connection, which causes increased demand on battery power. To prolong the operating time of your device, select Menu > Settings > Connectivity > Admin.settings > Packet Data (Mobile Data) > Packet data connection (Mobile data connection) > When needed. 
11. The Maps application downloads new map information when you scroll to new areas on the map, which increases the demand on battery power. You can avoid the automatic downloading of map data by downloading the needed map data via PC to your device.
12. If the signal strength of the cellular network varies much in your area, your device must scan for the available network repeatedly. This increases the demand on battery power. If the network mode is set to dual mode in the network settings, the device searches for the UMTS network. If it is not available, the device uses the available GSM network. To only use the GSM network, select Menu > Settings > Connectivity > Network > Network mode > GSM.
13. The backlight of the display increases the demand on battery power. To change the timeout after which the backlight is switched off, select Menu > Settings > Phone > Display > Light time-out. To adjust the light sensor that observes the lighting conditions and adjusts the brightness of the display, in the display settings, select Light sensor or Brightness.
14. The notification lights can be turned off to save the battery. Select Menu > Settings > Phone > Notification lights and disable the breathing light in Breathing light (or Standby breathing light) and adjust the light settings for different events in Notification light menu.
15. Leaving applications running in the background increases the demand on battery power. To close the applications you do not use, press and hold the menu key, swipe to the application in the list and close it by selecting X.
16. Pay special attention that you don't leave applications running in the background which are using GPS or network connection, for example Maps, if you are not using these applications.
17. Home screen widgets may periodically connect to internet if the home screen is in online mode. If you are not actively using the widgets, the automatic connection can be disabled by selecting Options > Widgets to offline mode on the home screen (Symbian Anna and earlier).
18. Installed 3rd party applications may consume extra power. Uninstall the application if you have noticed that power consumption has increased after the application was installed and if the application is not needed any more.
19. The AMOLED display in your device consumes more power with white color. Therefore the themes with a lot of white colors (e.g. in wallpaper image) may consume more power than the other themes.
20. When connecting to the internet, use a WLAN connection, rather than a packet data (GPRS or 3G) connection.
21. When you are listening to music, and do not want to make or receive calls, activate the offline profile..

It is recommended that you use the Nokia battery charger (AC-15) that was included in the sales package of your Nokia device. This charger is optimized for your Nokia device's battery.

You should uninstall the UMU MS full application from the Nokia Belle device before upgrading to Nokia Belle Refresh or Nokia Belle FP2.

If you have upgraded via Nokia Suite, the UMU MS full application will reset phone when you launch it. We recommend uninstalling the application.

The UMU MS full application has been removed from Nokia Store. The problem in the application is under the investigation of a third party. The application should not be reinstalled until issues have been fixed by the third party.

In case you have downloaded and paid the UMU MS full application from Nokia Store, contact Nokia Care to receive a refund.

Note that after updating to Nokia Belle Refresh, just like after updating from Nokia Anna to Nokia Belle, some apps may not work due to compatibility issues.

For more information on available apps, please contact your local Nokia Care support. Furthermore, you can also contact the respective App developer to enquire about the compatibility.

1. Disconnect and reconnect the charger.
2. Be sure to use the Nokia battery charger that was included with your phone. Older chargers may not fully charge the battery, or may take longer than normal.
3. Try the charger with another compatible phone to check if the problem is with the charger or the phone.

If the battery is completely discharged, it may take several minutes before the charging indicator is shown or before you can make any calls.

Pinch-zoom doesn't work if the web site developer has defined the following meta tag on the web page:

user-scalable = no

The above tag may be in use e.g. on mobile optimised web pages and it disables the zooming by the user. The tag is supported by the newer browser versions, e.g. Symbian Anna (and later) and MeeGo browsers. According to the specifications, the user is not allowed to scale the page in the above situation.

ColorizIT application is not automatically installed when updating from Nokia Belle to Belle Refresh. The application will be available as a separate update for eligible devices via the SW Updates menu on the phone or via Nokia Suite Software Updates menu.

For some reason the Mac computer is not receiving the updates.

You can do the manual checking.  On Mac computer : Go to tools and settings, and do 'Check for updates now'.

CommuniTake is a remote support tool that can be used by Nokia Care in certain countries to assist Nokia customers in solving their problems. The application is available to be used only with Nokia Care and the connection to the customer device can be opened only with the customer acceptance.

EAPlugin Error means that there is some problem in authenticating to your WLAN network. Check that the settings defined in the EAP plug-in settings menu in your phone WLAN settings are correct and match with the settings in the WLAN access point.

You can format your device by typing *#7370# in standby mode. Before the device is reset, you may need to provide the lock code. The default lock code is 12345.

IMPORTANT NOTICE!

• Formatting the device will permanently erase all user data and settings as well as add-on applications and operator specific settings.
• If you have made a backup of the device data, the data can be restored from the backup after formatting but some add-on applications can have restrictions that they are not restored from the backup.
• If you use formatting to repair faulty behaviour of the device, restoring the backed-up data files may restore the unwanted behaviour as well. In that case, a partial restore may resolve the situation.
• The contents of the SIM card and memory card (MMC) are not erased during formatting. Note, however, that in some device models (e.g. Nokia N8-00, E7-00, E6-00, C7-00 and X7-00) the internal mass memory E: will be formatted in this situation. It is therefore important that you back up all your data from the E: mass memory before resetting the device. Use Nokia Suite to back up the contents to your PC.
