hi, my nokia n86 doesn't switch off properly sometimes. When I streaming a video the device sometime freezes. When this happens I'm not able to close the frozen application although I can open/close other applications. The only option I have to close the frozen application is to switch off the device. When I switch off my mobile, it still shows my screen saver
(which is t

he time and date) and I cant switch it back on. To fully turn it off I remove the battery. Please help!
