Venu 3s Bluetooth range problem

As with some users, my wife's watch also has a problem with Bluetooth functionality, with very weak range and disconnection from the iPhone. The Epix2 had exactly the same issue, which I solved in my case by using this method. The question is, can something like this be done with the Venu3?

  1. Hold the menu button
  2. Select Connectivity
  3. Select Phone
  4. Select Press light button 5 times in quick succession>
  5. Select Maximize Compatibility (Toggle on)
  6. Select Sync with GCM
  • Select Press light button 5 times in quick succession>

    On my epix (Gen 2) it's 4 times, and if you press it too fast, it turns on the flashlight. I don't believe the Venu 3 has this option, as it is a different firmware. Possibly a different sequence to get into hidden menus. Certainly nothing publicly documented by Garmin.
