In Windows Mobile or Android, when I press call button and type a short sequence of numbers, my phones will auto list all contacts and call histories (missed calls, dial calls, receive calls) that contain that sequence of numbers I have just typed. For example, if I press 085, the phone will list all contacts and call histories that contain 085 like 085xxxxxxx, 0xxxxx85xx, 0x8xxxxx5 or +xxxx80xxx5..., ect. That is used when some strange numbers call me and I'm not free to answer but I only remember some parts of those numbers so when I want to call back, it's easy to find. In addition, when somebody asks me who is the owner of the number and I can press some parts of number to find the contact's name very fast. So in OS7, how to search Contact name and call history by typing number?
