This is bugging me about Whatsapp. My contact list in the app is presumably the list of contacts I have in my phone book who have whatsapp. I can see their picture and status if they have one. But their actual usernames are as I have inputted them into my phonebook. However, I'm sure it should appear as they have chosen their names to be (because I can choose how I want my name to be in the edit profile section). It may seem trivial but I'm worried I'm missing something or have done something wrong - does anyone know? Thanks.
PS I have a samsung galaxy s2 android 4.1.2
