Apart from using WhatsApp to chat with your friends and family, you can also use the app to call them. If you frequently use WhatsApp calling and wear a Wear OS smartwatch, you'd know that you won't get any notification for the incoming call—forget about taking the call. At best, you can hang up the call after you have accepted it. This led to a frustrating user experience and was a puzzling limitation since you can receive regular calls on Wear OS watches. Now, if you own the Wear OS 3-based Galaxy Watch 4 or 5, this will soon no longer be an issue.
