update: no more step tracking, sleep and inconsistent heart rate

Hi, I´ve already contacted garmin support, they asked me to factpry reset my device, but the issues still percist; please help.

Any empty file called force.tmp should work. Both files need to be in the Garmin folder. The FR165M firmware won't work on the normal 165.

Since January 18th (following a software update), I have been experiencing these issues as well.

When I contacted Garmin Support, they asked me to install "Garmin Express" on a laptop for data backup and to perform a hard reset on my device. I couldn't install the software, but I did perform a factory reset and removed the device from my phone's Bluetooth settings. I also uninstalled and reinstalled the "Connect" and "IQ" apps, but the problems persist.

Below are the issues I have noticed on my device:

Daily Use:

• Rapid battery drain: The battery only lasts 2 days.

• Inconsistent HR readings: It stays between 72 and 80 BPM regardless of activity.

• Tracking failures: It does not track sleep or HRV, which affects the recovery indicator (showing "prolonged" recovery due to lack of sleep data).

During Activity (Running, HIIT):

• Heart Rate issues: It does not track heart rate correctly (stays in the 72–76 range). I used an older device (Forerunner 245) simultaneously, and it displayed my heart rate correctly.

• Input Lag: There is a 10-to-20-second delay when starting or stopping an activity after pressing the button.

• Faulty Cadence: Cadence readings are very low, even when increasing speed.

• Inconsistent Running Pace: The pace increases intermittently; it initially displays a low pace, then "jumps" or accelerates to catch up once the GPS updates the distance covered.

I request your support with these issues, as they are significant and have persisted for a considerable time.

Tengo problemas con el Forerunner 965 en los datos de la frecuencia cardiaca. Han habido días que ha marcado fatal. 

Look on page 9. There is a link to an older firmware for the non music version and a link to the music firmware with instructions on how to downgrade. If you're not technically inclined then rather wait till Garmin brings out an update to fix the issues.

I'm seeing the same thing! And the issue has been consistent too - heart rate stays at 74-76bpm even if I push myself (or even if I know I'm staying at zone 2 but I know this is obviously not). Garmin fix this please!

I've been in contact with Garmin Support and they acknowledged the issues , they have a ticket raised and noted that its been worked on but no timeline to resolve unfortunately.

I don't have anything other that above from them.

Seeing as Garmin obviously doesn't give 2 shits about their customer base, which other watch brand/model would be a 165 or even a 570 competitor? Going to look elsewhere as this service is unacceptable 

My sleep tracking steps have stopped working since the update of a few days ago severed my connection to Connect. It hasn’t worked correctly since I reconnected it. Running a medical study with a university medical school using his Epix Pro Gen 2, and now I’m missing vital sleep data after 1.4 years of this study. Please advise
