Troubleshooting for Nokia Lumia 800

If your memory card or mass memory is not working properly, check the following:

1. Use only compatible memory cards approved by Nokia for use with your device. Check the user guide or the technical specifications at Nokia support pages for more details
   
2. Check that the memory card is properly inserted in the memory card slot. Push the memory card to the bottom of the slot.
3. If possible, test with another memory card to see if the issue is in the memory card.
4. Check that the device is not connected to PC. Depending on the device and the connection mode, the PC may reserve the mass memory and memory card for exclusive use and the memory drives cannot in this situation be accessed from the mobile device. Unplug your device from PC and try again.
   

If the memory card or mass memory is not working properly, try backing up any data from your device's memory card or mass memory to your PC, then format the memory card or mass memory by using your Nokia device. Depending on your device, the memory card can usually be formatted in one of the following applications (select the application, open the desired memory device and in the available options select the command to format the memory card or mass memory):

• File mgr.
• Memory tool
• Memory card tool

Refer to your device's user guide for more information on how to format the memory card or mass memory.

If you get an error message during the formatting process or an error message after formatting stating that your device cannot read the memory card volume or mass memory, take the memory card or Nokia device (in case you have internal mass memory in your device) to your nearest Nokia care point.

Warning: Formatting your memory card or mass memory will permanently erase all data stored on the memory card or mass memory. Please back up all data stored on your memory card or mass memory before formatting.

Important: The memory card or mass memory inside your Nokia device should ONLY be formatted using your Nokia device. Do not attempt to format your memory card on another device such as a PC, otherwise your memory card may not work properly.
 

The phone notifies you if the phone memory is getting low. To free phone memory you have the following options:

• Move data that you want to keep to an alternative memory (mass memory or memory card, if available) or to a compatible computer.
• Remove data you no longer need.

Use File Manager or the respective application in your phone to remove data or to move data to alternative memory as described in the user guide. Typically you first mark files to be removed or moved and then you select the corresponding option (Delete or Move to folder).

Use Nokia Suite to move data to a compatible computer.

To maximize free spaces to your phone memory, you can remove or move the following:

• Messages from Inbox, Drafts and Sent folders in Messaging
• Retrieved e-mail messages from the phone memory
• Saved Web pages. Clear the web browser cache to free some phone memory (e.g. select Options > Clear privacy data > Cache).
• Saved images, videos, or sound files (in Gallery, Photos, Videos or Music player)
• Contact information (in Contacts)
• Calendar notes (in Calendar)
• Downloaded application packages
• If there are applications which are not needed any more, uninstall them with Application Manager
• Any other data that you no longer need

If you are deleting multiple items and any of the following notes are shown: Not enough memory to perform operation. Delete some data first or Memory low. Delete some data, try deleting items one by one (starting from the smallest item). After deleting data, restart (power off/on) your phone.

Tips: Use the memory card or mass memory instead of phone memory in the Camera or other applicable applications in case the selection is available (e.g. via Options > Settings > Memory in use).

1. Restore the original factory settings on your Nokia phone. For information on how to do this, see your Nokia phone's user guide (your personal data is not deleted in the reset). Retry.
2. Contact your network operator to check that Internet browsing (data connection) is included in your service contract (SIM card). Also verify that roaming is supported when you are not within your home network.
3. Make sure your Nokia phone is running the latest software. For downloads and assistance, go to ýour local Nokia website's support page.

The blinking closed envelope icon indicates the SIM card message memory is full.

Select Menu > Messaging > Options > (View folders > Options) > SIM messages and delete one or more SMS messages.

Note 1: Class 2 messages (for example, service messages from operators) are stored in the SIM card message memory. Once the SIM card message memory is full, Class 2 messages can't be received. 

Note 2: You have used a Nokia S40 product before. In S40 products the SIM card message memory is filled before the device message memory. If you insert a SIM card with full message memory to another device, a blinking message icon appears on the display of your Nokia device.

Note 3: Other reason could be that there is not enough free memory available on the device to store the new message. To release a space go to Messaging > Inbox and remove unnecessary messages

Perform the following steps (until the solution is found):

1. Turn off your Nokia phone and remove the SIM card .
2. Turn on your Nokia phone (without SIM card).
3. Turn off your Nokia phone and reinsert the SIM card .
4. Turn on your Nokia phone. Retry.
5. Restore the original factory settings on your Nokia phone. For information how to do this, see your Nokia phone's user guide. Retry.
6.  Contact your network operator for the correct SMS settings.

If there is no response when tapping the touch screen, check the following:

1. Check that the device is not locked. When the device is locked, you must use the lock switch to unlock and wake up the screen.
2. If the device is not locked but only the display light time-out has expired and the display has dimmed (a situation which may occur if Keypad autolock feature has been disabled), the touch screen can be woken up by pressing any mechanical keys like menu key, volume keys, camera key or the lock key (lock key needs to be pressed twice because the first press of the key will lock the device).
3. If in a phone call, check that the proximity detector at the upper front corner of the device is not covered. The proximity sensor will lock the touch screen to avoid unintended touch screen actions during a phone call when placing the device next to your ear. Check that the proximity detector is not covered if trying to use the touch screen while a phone call is active. 
4. Remove the battery and reboot the phone.
5. If there is a memory card in the phone, try booting up without the memory card.
6. If your phone supports touch screen calibration, try to re-calibrate the touch screen (select Settings > Phone > Touch input > Touch screen calibration).
   

If the touch screen doesn't yet respond, try restoring the factory settings. If you cannot access the factory settings menu via the touch screen (Settings > Phone > Phone mgmt. > Factory settings), try entering the following reset commands via the keyboard. Before resetting the device, take a backup of your phone via Nokia Suite.

• *#7780# (try this first, it will do a soft reset).
  
• *#7370# (try this if the above command doesn't help, this command will do a hard reset).
  

If the touch screen is not yet working properly, take the phone to Nokia care point for inspection.

The calling phone number may not match with a contact name and the name is not shown in the following situations when an incoming call or SMS arrives:

• The contact is defined twice in the Contacts application (e.g. if both Phone memory and SIM memory contacts have been selected to be displayed in Contacts settings and the same contact is found in both of them).
• The same phone number is defined for two or more contacts.
• The phone number in Contacts application is in different format than the number received in the incoming call. The phone number may have been stored in local format while the incoming call number is in international format (including country prefix), or vice versa. The number may not be properly matched with a contact name in this situation, depending on the device variant and the length of the calling number. In order to verify the correct format of the contact phone number (local or international), check the number which is shown when the call is received and edit the contact details accordingly.

If the problem persists, make sure your Nokia device is running the latest software. For downloads and assistance, go to your local Nokia website.
