I am using Nokia 7210 Supernova mobile from three months. But from few days this Nokia mobile is showing very strange error message. Whenever I try to play music file or any video file I immediately get error message saying that 'Not enough memory'. I also tried to release the memory from my mobile, but still getting same error message. If anyone posses solution to resolve this issue of Nokia 7210 Supernova, then try to share it with me. I will really appreciate your any help.
