My wife just got a Samsung Z Fold 2 (old phone died, limited choices), which I love and she is … adjusting to. The one real problem she’s having is that while using an app (Samsung’s email app, for instance) with the screen unfolded, the 3 buttons at the bottom right (the standard Android Recent apps / Home / Back buttons) don’t work. They don’t do anything at all when you tap them. If she puts the phone to sleep and wakes it back up, or even just partially folds then unfolds it, they come back to life. It’s very annoying. Any thoughts? Thanks.
