I have an app that stores previously saved information, for viewing and editing. When it is edited, the user chooses which piece of info (from a list) and can then currently change the sections.
I have it set up that the fields that can be changed are auto filled with the existing information, so it can be edited. However, it is not easy to edit text on phones sometimes, and I want this to be easy to use.
Another option I have is to not auto fill anything into the boxes - but any box that they don't add information to is left as it was. This would make editing easier, but may be less intuitive.
What is the standard for these sorts of things?
