Designing edit profile screen

I am designing edit profile screen for android mobile app have several fields (profile pic, full name, username, intro, career, interests and etc) to filled out by the user.

Possible user flows

  1. Profile -> Edit profile -> Edit intro (separate screen to edit a specific field)
  2. Profile -> Edit Profile (edit on the edit profile screen itself)
  3. Profile -> Edit Profile -> Dialog to edit a specific field

Pros and cons of the each approach as I see.

  1. Pro: No clutter with other due to other fields, Cons: 1 more click for user to edit a particular info.
  2. opposite of the first approach
  3. similar to first approach

For now I have total of 9 fields, it may increase in the future. So what is best approach to to give optimal UX for the user when editing profile? Any tips, more things to consider are welcome.

I was not able to find UI mocks on this topic, so UI mocks of edit profile screens are welcome.
