Showing/hiding the bottom edge hint is a tricky one.
The proposal to hide the hint if you scroll up in the screen won't work with all applications. Especially with those, where there is no view to scroll, e.g. dialer app.

The initial idea was to show the hint for the first 3-5 times after launching the app, because user will learn what the bottom edge does.

The recommended solution can be either a combination or change to the following points:
1. Extend the bottom edge collapse to 5sec &/or
2. Only collapse the hint after user starts interacting with the content of the screen; dialer - typing numbers, address book - scrolling, etc
