[BUG] FW 15.19 - Heart rate and step issue

Hi, after update FW15.19 and full charge 955, i observe some issue on my heart rate data and steps counting.  Steps data was not moving at 0 value. Heart rate is constant at 77 for a long time , when I check the HR graph, it's a flat chart of 77... 

I have sync with Garmin Express, reset my 955, HR and Steps remain an issue.  What should I do next ? 

 please assist me on the above issue.  

I started my run , and it did not detect my HR data despite having green LED OHR blinking.

  • I have furthered checked, the green LED optical HR sensor light is blinking , thus I believe its working, just that, it's not broadcast HR,  I try to manual broadcast under Sensor/Wrist HR/broadcast HR, however, it does not reflect on the HR graph, remaining at " -- " both the HR graph and watchface.  Step sensor is not gathered any steps data, calories is normal though.

    I have reset my watch, delete all settings and activities.... Do I need to restore factory settings?  Anyone having similar issue or Garmin support that can assist me on these issues.

  • I am reading FR955 manual (page 47), there suppose to be "Activity Tracking Settings" , Hold left middle button, then scroll to "Activity tracking", I can't find this anymore on FR955, has it been renamed ?   I wonder if this has been turned OFF?  Where could I find this ? 

  • I have exactly the same problem. In addition, the altimeter no longer works...

  • I'm on 15.19 also but I not have these problems. HR works like a charm when I running. I only detected some occasional delays to connect to my external HR strap that I use for my cycling activities (I need to exit from cycling sport mode, wait a while and reenter to the cycling activity to the HR display correctly the external sensor, but only few times).

    If you already reset your watch maybe the factory reset should be the best to discard any other problem and start again from zero.

    You can find this options at:
    Middle button > Settings > Health & Wellness > Wrist Heart Rate

  • It also takes very long from press start an activity until it really starts.. (overall also quite bad performance..) 

    it there a possibility re-install the software? because i did the full reset but with no improvement..
