My phone is nokia n70 . my nokia n70 change automatically function. come to the visual redio and music players many times.and not any work that time hang position finally i switch off my mobile

Hi,
your phone might be hanging because u don't have enough memory space on the phone memory, try freeing up some space by deleting some items like media files that is stored on the phone's memory. Hope you know that for the visual radio to work you must connect a headset to the phone to act as the antenna.
hope that helps
