Hi All, I wrote the Gear Tracker App. I've seen issues with HR since Tizen 3. The reason Gear Tracker works continuously is that I detect the HR API lock up and restart the sensor after 30secs. I also have issues with high readings. I've also noticed on my Gear S3 since the recent update the issues have worsened for me. Check out my posts at https://facebook.com/GearTrackerApp I have had an open ticket with the Samsung Developer Program on this for several months now and have been continually updating it with ongoing issues, and info from other posts and users like here. I've actually had a response from support showing their own test results and confirming they were able to reproduce the issue on Tizen 188.8.131.52! They've also stated that this info has been forwarded to the HR team for review. I'll keep pushing for a response. As far as I'm concerned this is a software issue as it worked fine under tizen 2.3.2. I beleive that Samsung are so focused on saving battery usage that everything else comes second and gets overlooked. As a developer it's a very challenging working on this platform. Finally, I'm continuously looking into ways to overcome or fix these issues, hopefully one day soon Samsung will sort this out.
