title: Allowing the user to undo a "don't ask again"?
body: <p>In Android if you ask for permissions, second requests onward allow the user to check "Don't ask me again" so the failure state will always be reached in the future.</p>
  
  <p>What if the user changes their mind and wants to allow permission, but can't now because the feature defaults to the permission-fail state? How can the user undo their "don't ask again" setting?</p>
