Instructions for installation are available below the change log on each of the above pages.

19.78 Change Log Notes:

  • Improved altitude calibration.
  • Fixed fonts used on the activity timer when the device is set to French.
  • Fixed intermittent issue that would cause device shutdown while saving an activity.
  • Fixed Tennis, Pickleball, and Padel outdoor activities to only prompt the user for altitude calibration when the device’s Altimeter Auto Calibration setting is set to Nightly.
  • Fixed issue with HIIT activities where the Workout Complete banner would continually be displayed after completing a HIIT timer workout.
  • Connect IQ improvements and bug fixes.
  • Other minor improvements and bug fixes.

Please send all bug reports to [email protected], and indicate which model of the Fenix 6 Series you have in the subject line

  • I'm in the same situation as you. I do manual calibration twice a day (outside, before starting activity, using DEM), and after I'm back indoors (to known altitude). Works quite well, no weird jumps/flat spots/spikes in alti or baro, only thing is the alti graph misses parts sometimes, but thats not that important to me.

  • Yea but manual is annoying and I don't really see many people in a situation where this nightly auto calibration is going to work, all the people I know are in the same situation as me.

    For me the "connect a height with known WiFis and check for them to calibrate" would work, but then that's only for the versions with Wifi. Could be extended with the phone connection to have the phone check that for the non WiFi watches, for the people who keep the connection alive.

    But I can't imagine there are many people living in a tent with GPS reception at night and on the ground for DEM calibration.

  • But I can't imagine there are many people living in a tent with GPS reception at night and on the ground for DEM calibration.

    Agreed, but for first floor the error is negligible, and could always use GPS calibration instead.  I can imagine auto calibration is more for people who are out adventuring and perhaps sleeping out. For me, calibrating before each activity works well as I run every day.

    And known wifi would only work for the Pro watches, as the non-pro's dont have wifi.

  • No one I know is living on the first floor. I don't know about other countries, in Germany the buildings made out of concrete usually don't have GPS reception and most people live in buildings. Sometimes with luck and a sensitive receiver (the watch isn't that sensitive) it would be possible by a window, but a weak fix does not give a correct position or correct height information. And you still would have to sleep next to the window. And then people do stuff like closing metal blinds on the windows to keep the light out for sleeping.

    I just don't see the usage scenario of this specific feature.

  • I just don't see the usage scenario of this specific feature.

    As I said, I imagine its for when people are out in the field, perhaps camping etc on multi-day activities. However they do auto calibration, there will always be good cases and bad cases. One mans meat is another mans poison and all that.

  • No one I know is living on the first floor. I don't know about other countries,

    Quite common here. I live in a small town and many houses are 2 storeys max. Quite a rural area, And although I don't get a very good GPS fix on my watch in my bedroom, the phone does surprisingly well. We've mostly slate roof houses.

    I can imagine the bext way forward would be to offer a variety of auto-calibration options to try and cast as wide a net as possible for people

  • Mobile phones use additional information for location detection: Carrier services and WLAN information. For a realistic comparison, switch off all services on your mobile while being some (10 or 20) miles/kilometers away from home. When back home, switch on only the GPS on your mobile and wait for the location detection. You will most likely get the same (poor) reception/detection than with a pure GPS device.

  • Maybe I misunderstood, but I thought that nightly calibration uses either Wifi or a BT phone connection, not GPS?

    I just can't imagine calibration using GPS at night would work in a brick or concrete building. Esp. with energy-saving window panes or shutters, and interference from all kinds of sources. It's often even hard to get good cellular phone coverage indoors.

    For me, GPS indoors did work in the past (same building, same watches, Fenix 1 and 2), probably because there was less interference back then. They now maybe see one or two satellites indoors, sometimes, weakly. 

  • Oh I agree, but here the watch calibration, if done levering AGPS on the phone would work well for some.

  • I’m not sure how they’re doing it, but if they are relying on a BT/WiFi connection it would make sense to use the phones AGPS to improve accuracy
