Fenix 7X Pro - possible defect with compass and altimeter?

Hi forum, since a few weeks ago, possibly with a beta update, my watch started acting up.

  • First symptom was a compass not settling in the widget and the mini version of it, it keeps spinning and is way off the "true" north from the map at my home.
  • I destinctly remember it to be spot on and settling after a second or so, and it could catch a slight rotation with tremendous accuracy. Well, not anymore.

Then, during mountaineering and hiking, I notice the alimeter to count too much elevation gain, both up-hill and down-hill. During an activity:

  • On the map, I will see very short lateral "jumps", consistently, but seemingly random direction.
  • The altimeter seems to act up, see attached picture. The altitude will jump exactly by the same amount, but at random intervals.

Has anybody experienced something like this?



For the record:

  • Yes, I recalibrated the compas nmerous times.
  • Yes, I restarted the watch.
  • Yes across the beta updates the error is consistent and present.
  • The altimeter port seems clean, and this shouldn't affect the compass at all.
  • The only IQ field I have installed (and enabled in the hiking activity) is the one that records tempe values into a FIT file field, since I want skin temperature and env temperature separately recorded.
