Amazfit has announced a new software updated for its latest GTR 3/3 Pro and GTS 3 smartwatches. It functions to fix some pre-existing bugs in all 3 devices - however, in the case of the highest-end GTR 3 Pro, it also enables the user to set it to send SMS messages by itself in response to incoming calls or other events such as WhatsApp messages.
