Why does the green light flash when I take of my smart watch?Updated a month ago

The green light on your smart watch is part of the heart rate sensor, which uses light to detect your pulse. Your watch will attempt to measure your heart rate at regular intervals—typically every 5 minutes. This function continues even when the watch is not being worn, which is why the green light may flash after removal. Sadly, this watch does not have the ability to turn the tracker off.
