I have a problem with my nokia n95 that I just bought. In fact, when someone calls me his number or his name does not appear, even if the caller is already saved in my contact list and the display name of the caller is enabled in "settings".
contact> Options> Settings> Display Contact .......... There are several choices, if everything is checked, the phone may be malfunctioning. It is best to choose "phone memory",as primary storage for your contact.
