The Redmi Watch 5 Active can only answer calls from the Phone app and cannot answer calls from third-party apps. The device is designed to work seamlessly with the Phone app for receiving calls. However, it does not support answering calls from third-party apps like WhatsApp, Telegram, or Facebook Messenger.
Additionally, it does not support making outgoing calls or initiating calls. For making calls, you would still need to use your smartphone or a device that supports this feature. Additionally, the watch offers the ability to mute or silence the call, allowing you to manage notifications discreetly.
While it provides basic call-handling functionality, it's important to note that the watch is designed primarily for fitness tracking and notifications, not as a replacement for more advanced communication features.
