Heart Rate Monitor Incorrect Following 27.09 Update

4206607

I am noticing the heart rate monitor is incorrect following the 27.09 update. I have tested with my Garmin Forerunner 165 Music in built heart monitor and my Garmin HRM Pro Plus external monitor when running.

I have tried rebooting the watch multiple occaisions, but it does not recognise when my heartrate increases when running.

Anyone else experienced something similar since the latest update?

    Hi, I have the same issue. After the 27.09 Update the heartrate is constant between 72-80  idependent what I do. No sleep is detected anymore and body battery is also not working. This is a shame! My forerunner 165 is now useless for me. I resettet the watch which did not help. Does someone has an idea how to downgrade to the old firmware? Is Garmin aware of this *** Firmware 27.09 Bugs?

    I have the same issue with FR 165 after this *** update 27.09. Before this update everything was good but now the heart rate is constant at 72-80 bpm, the body battery and sleep detection is not working anymore. Also the tracking is now very slow when starting the activity... I tried to reset which did not help. I want to downgrade the firmware but don't know where to find the old firmware. I hope Garmin is aware of its stupid firmware release ...I think thousand of Forerunners are not working anymore properly. My FR seems to get several debugging updates which also not helped. Is this watch now damaged?

    I'm also experiencing the same problem. Yesterday, my heart rate was dropping intermittently, from 135-140 to around 70. This only happened on my second run after the update. I didn't have any problems before the 27/09 version. Could you please check and fix this ASAP?

    Hi, is someone from Garmin reading this and also other topics related to update 29.07? Are you aware that you made millions of watches useless with your glorious update? How are you working? are you testing updates before rollout? I'm frustrated because my FR 165 is now useless for me and my training.... perhaps better now changing the brand.

    I’m experiencing the same issue. Was fine before the 27.09 update. After the update, HR monitor has been completely inaccurate. Stuck in the 70’s even when running all out, then jumps up to 150’s for few seconds than drops back and stuck in 70’s again. Garmin can you pls fix this.

    I’ve had the exact issues others are describing for the last two weeks since updating. I contacted support, no reply, and am now finding these forums in my frustration. I completely agree with you above. Why can’t I find any responses from Garmin anywhere?! Not even acknowledgement of the issue and some sort of statement that they are working on it. Please Garmin tell us all what’s going on.

    I made this post 2 weeks ago and still no update from Garmin? The watch is completely useless now. What is being done to fix this issue? What compensation will be offered?

    Agreed. Communication is always key. Just some transparency about what went wrong and a timeline for fixing it would be really reassuring to a lot of people. Silence is only leading to a lot of resentment from what I’m reading on these forums.

    No, this has been a problem for about a year and a half...it was an update a long time ago that messed something up. Still waiting for the update that fixes it and improves Wrist HR and Sleep so it's at least not in the bottom 50% of Wrist HR and Sleep trackers on the market. Everyone else is improving their algorithm while Garmin's seems to be going backwards, I was hoping this 27.09 was the one that bring massive changes. It seems better to me honestly, but that could just be hope, if others are still having serious issues, maybe it isn't, or maybe it's something else where users need to circle back to proper guidance on how to wear and clean the watch? Just my two cents
