Review on 🌟 SAMSUNG Galaxy Watch 3 Titanium 45mm Mystic Black - US Version, GPS, Bluetooth, Advanced Health Monitoring, Fitness Tracking, Long-Lasting Battery by Amy Cummings

I will be returning my Samsun Watch 3 Titanium for the second time this week. It won't detect my heart rate, O2, stress level, etc. except on rare occasions. Of course I tried to wear it properly and also tried to wear it with the sensor on the inside of the wrist, over the veins/arteries. This watch is too expensive to have such a defect. My Samsung Gear S3 worked great.
