There should be some very basic safeguards to help users discern what is “real” in the UI:<p>1. Every user should be able to select a custom color and pattern, e.g. to display around the border of system UI. This should be stored in such a fashion that an app can’t simply “guess” what color/pattern to show in a fake UI.<p>2. Part of the “set up new device” overview for all new users should be to remind them what the UI is supposed to look like.<p>3. For crying out loud can we move away from these simplistic, ugly UIs. I’m tired of looking at unimaginative colored rectangles on machines capable of displaying cool, photo-realistic artwork. Make Google/Apple/etc. hire entire teams of hundreds of artists to create cool, extremely-difficult-to-render UIs with beautiful buttons, etc. and then bad actors won’t be able to just hack together a real-looking UI in 5 minutes.
