“Memory Full…Close some applications and try again” is a normal
message that usually comes on Nokia N70. It showed the memory used in
the phone doesn’t have space anymore. But if the message still appears
although the user already closed some applications it can be the
problem.

Someone who experience in this memory full problem said, an error
message of memory full like above is appears each time he’s opened the
Camera. It also happens for a few times when he’s trying to open
messages, Gallery, or other applications. And then it will force to
restart the phone.

Seems like it’s a RAM problem and might there are some applications
unable to close completely. If your Nokia N70 phone has gone a start
menu button you can try to hold it down. This way will show you
everything that you have open and they can be closed easily so that
you can continue to take your photos.

So if it can resolve the problem you can reset/format by pressing
*#7370#. If that doesn’t work there are some other things you can do
such as re-installing your phones firmware.
