Can I save pictures and videos I've taken using my Nokia phone to a memory card?

Yes, your phone supports a memory card. The default location of photos and videos changes to the memory card when you insert a card in your phone.

To see your photos and videos on your phone memory, select Menu > Camera > Photos (or Videos) > Options > File location > Phone memory.

You can also select Menu > Photos (or Videos) and read the popup notice on how to see the files on your phone memory.
