A new Beta software for the Forerunner 935 has been released. Full change log, instructions, and software for installing the beta can be found here.

[h=4]Changes made from version 6.75 to 6.78:[/h]
  • Added an Alarm Clock Hot Key. Go to Settings > System > Hot Keys to enable this.
  • Added an Alarm Clock Control. Go to Settings > Controls > Add New to enable this.
  • Improved backlight behavior to remain on in certain cases. If your backlight setting for 'Keys' is enabled, the backlight will remain on while waiting for data after navigating to some pages.
  • Improved the user interface for chart pages namely, altimeter, barometer, temperature, and optical heart rate history.
  • Improved the user interface for the charging page.
  • Fixed an issue where the dog widget occasionally displays random symbols for dog names followed by a crash.
  • Fixed an issue where the Power key would inadvertently turn on the backlight.
  • Fixed an issue where segment alerts were seen while using a Connect IQ app.
  • Fixed an issue where emojis with a modified skin tone were not displaying correctly.
  • Fixed an issue where the connection error image on certain widgets did not look correct.
  • Fixed an issue where goal alerts backlight/tone/vibration were not being suppressed when Do Not Disturb was enabled.
  • Fixed an issue causing an empty row to be displayed in the lap summary pages for Indoor Cycling activities done without a Speed/Cadence sensor.
  • Fixed an issue where Strength workouts with repeats that end with a Rest step could show incorrect information about the next Set.
  • Fixed an issue causing step numbers to be displayed incorrectly in Strength workouts.
  • Fixed an issue causing the Rep Counting page to replace the Virtual Partner page in some activities.
  • Fixed an issue causing incorrect settings to be applied when copying Apps.
  • Fixed an issue causing the Grade data field to incorrectly show '0' at times.
  • Fixed an issue preventing Wi-Fi syncs when a LiveTrack session is in progress.
[h=2]Installation Instructions[/h]
  • Connect your Forerunner 935 to your computer using the USB cable.
  • Download and unzip Forerunner935Beta.zip. Place the GUPDATE.GCD file in the \GARMIN folder of your device's internal storage drive.
  • Disconnect your device from the computer, approve the update on the watch, and wait for the update to finish.
  • If you would like to revert to the last public release software, follow the above steps but place the GUPDATE-610.GCD file in the \GARMIN folder. Rename the file to GUPDATE.GCD before disconnecting your device. NOTE: If you revert to an older version of software, all of your settings will be reset to defaults.
Please feel free to discuss this beta version in this thread, but be sure to also submit any feedback to [EMAIL="[email protected]"][email protected][/EMAIL].
  • My backlight is set to only come on manually but when I press the start button to go into activities the light comes on and also causes quite a lag. The TE is also way too low but I think it was off from the previous beta too.
  • Resting HR resetting bug still in place :(
  • After the 6.78b I did a bike/run with transition activity.
    This activitiy did not was take in count for my trainning load/status.

    As far I am able to remember, this kind of activity usually appeared on my trainning status.

    Am I wrong or it is new?
  • Resting HR resetting bug still in place :(


    Which bug? I ask this because there's been either a change in how Garmin is interpreting our all-day RHR or it's just a bug and overreporting. I know somewhere on these forums someone posted how Garmin is doing it (for people that wear it all day including sleeping with it and those that take it off for sleep), but I can tell you that change is NOT a universal change if it is one in fact.

    I wear the 935 all day, and to bed. This watch has empirically reported my RHR in line with my actual RHR up until this change (38-42 bpm). Right now the watch is reporting my RHR exactly 10 BPM higher than my actual. How do I know that? Because when I did take off my 935 to charge, I true-up my data to my vivosmart HR and wear that until the 935 is ready. The moment I put the vivosmart on and it synced to CGM, magically GCM reported my RHR was right in line with my average. I literally watched the RHR change from 53 bpm (what it was getting from the 935) to 43 (after the vivosmart HR synced). When the 935 was done charging...it did the same thing in reverse.

    So either it's now how Garmin interprets our RHR here on the 935 and the way the Vivosmart HR is the old way of doing it and hasn't been updated, or the 935 is bugged and has been even before 6.78.

    If it's the latter, Hey Garmin, fix it in the next beta! If it's the former, it's wrong, by a proverbial mile. On a side note, the green filling watchface to designate charge status is nice...if redundant, especially when there is a giant percentile right smack in the middle of the watch face telling you how much of the watch is charged.

    From this link on Garmin support https://support.garmin.com/faqSearch/en-GB/faq/content/F8YKCB4CJd5PG0DR9ICV3A

    "RHR: This value is for the current day. It is calculated one of two ways. For users that wear their device while sleeping, the device will read and record the average of all readings while they sleep, excluding periods where any steps were detected or the measured heart rate fall outside reasonable bounds. A minimum of four hours of sleep time is required to register a reading. For users that do not wear their device overnight, RHR is determined as the lowest average reading over a one minute time period during the day."
  • That's it, thank you. And yea, that pretty much proves the bug in the 935. It's something in the interpretation of the data on the 935, because the Vivosmart HR gets the whole day (with Sleep) correctly, the 935 is then either ignoring my sleep and basing it on RHR the one minute time measurement, or is just plain wrong.

    Resting HR (in User profile settings) gets reset to no value after some time no matter what value gets inserted - either average or custom.
  • Please remove the first step of calibrating altimeter when calibrating barometer.
    It's redundant and annoying.
    We don't need to calibrate altimeter before calibrating barometer!
    And there is already an altimeter calibration function in altimeter app.

    Air pressure changes with altitude, and barometers measure changes in air pressure. So it makes sense to me that you should know the altitude at which you are calibrating your barometer.

  • Air pressure changes with altitude, and barometers measure changes in air pressure. So it makes sense to me that you should know the altitude at which you are calibrating your barometer.



    But it’s the air pressure at sea level that the barameter reads. Therefore, if you calibrate that properly it can tell you the exact altitude I believe
