I have purchased both the 46mm Galaxy Watch and the 44mm Active 2 and it seems either the heart rate sensors or the software on the watch and mobile app aren't showing accurate information. I had the 46mm GW first for 2 weeks and noticed a pretty big discrepancy between the heart rate data on it and my FitBit. Then after reading that the Active 2 had 4 more sensors for tracking heart rate I decided to give it a try but still getting the same results. It seem the sensors are accurately reading my heart rate but the detailed data being shown on both the watch and the Fitness app is inaccurate. For example, sometimes the watch and app will show a HR range of 30-166 and yet when you look at the graph my HR never goes below 45bpm and never goes higher than 130bpm. So it's like where do they get the 30 figure from and where do they get the 166 from? I took a pic of my watch and a screen shot of the app to show you an example.... http://imgur.com/a/4aCJ34o http://imgur.com/a/ahOwTgR Would like someone from Samsung to comment on this.
