What to do when the memory is full?
If either of the following messages is displayed when you are deleting several items at the same time, delete items one by one, beginning with the smallest items:
Not enough memory to perform operation. Delete some data first.
Memory low. Delete some data from phone memory.
Move data you want to keep to the mass memory or to a compatible computer. If possible, install applications to the mass memory, rather than the device memory.
