I have had my n95 for about 4-5 months now. Just one day last week, the number pad "9" stops working. Later I realized that number 9 and the red disconnect buttons are now linked. When I press either one, the phone presses both 9 and disconnect for me.
So this means I have a phone that cannot dial 9 at all!
Anyone has any experience? It is always in my car or in my pocket, and never dropped any water on it AFAIK.
