Ask Google about the meaning of life

Don’t do this. This was just my cheeky way of saying that you can ask the Google Assistant on the Galaxy Watch 4 most of the questions you’d ask it on the web. For instance, if you need to do a quick calculation or look up the weather, you can do that through the watch app, provided you don’t mind waiting while the app parses what you’re saying.
In its current iteration, the Google Assistant is slow on the Galaxy Watch 4. I tested it mainly on the LTE-connected version and sometimes ran into an issue where the watch would lose connection as the Assistant was looking for a result.
Also, take heed if you have multiple Google Assistant smart speakers and displays around your home. If you’ve got the hot word setup on your watch and you’re at home, you will trigger everything. With the watch directly on your wrist, it could add a little confusion to your household’s ecosystem.
