In Android autofill, favorite logins are not listed ahead of other logins. In the screenshot below, the “MAIN” login is a favorite, but it's listed fifth out of the six matching logins.
With the Firefox extension, favorites are always at the top of the list. It would be very helpful if that worked in Android.
