Memory card is in use by another application?

Answer 1

hey ppl..

its simple..jus check if any of the wallpapers or themes in your memory card is currently in use..if so,jus transfer it to your internal memory..thts it.

alternative:

this is not needed just check wether you are using any theme from memory with GIF image .. if yes then just change your theme that's it!

Answer 2

That is probably because your computer has the access rights to the memory-card on the phone.

If you check on "my computer" you might see your phone's memory card there..
