How do you delete a number in the memory of yoyr phone

[AC Question kelly74]

Iv deleted an unwanted number but and its not in my phone anymore, but if I go into messages and type in the name in the contact bar the name and number pops up, how do I stop this happening and delete it from the memory

Welcome to the forums. It might be still there due to your call/message history. Have you tried clearing that?
