  1. There’s a contradictory note in your review, Bluetooth calling. Can this device receive notifications from one’s phone? Example call and message notifications.

    • Hi Adebola, Bluetooth calling means that the watch is equipped with a speaker and microphone which means you can answer calls via smartwatch, But this Haylou watch does not support BT calling, it can just receive notifications from your phone.
