I remember trying "call <my wife's name as in my contacts>" a few years ago and Google Assistant cheerfully responding with "calling <first Google search hit with the same name>, doctor". I couldn't believe it, but back then, instead of searching my contact list, it searched the web and called the first phone number it found. A few years later (but still pre-Gemini), I tried again and it worked as expected. Now, some time ago, post-Gemini, it refused to make a call. This is basically the first most obvious kind of voice command that comes to mind when wondering what you can do with the assistant on your phone and it's still (again?) not working after years of voice assistant development. Astonishing.
