Fire-Boltt Smart Watch Troubleshoot - Sensor Issue
Please be informed make sure that the hand surface may not be clear like having hair or covered with moisturizer due to which the sensors are not performing. Wearing the watch very tightly can also be a reason due to which the sensors are not performing. If the surface of the hand is covered with tattoos then this can also be a reason due to which the sensors are not performing. If your issue still persists, kindly revert back to us on this email and we shall be happy to assist you with the replacement.
