My current guess is that it may have something to do with the compass auto-calibration.
I am almost certain this is this issue now. To check this, I performed the following:
Open the compass widget (make sure it is already calibrated).
Bring a magnet close to the watch (doesn’t have to be strong, a refrigerator magnet will work).
This will reset the compass and bring up the “Calibrate Compass” notification.
Without moving the watch, back out to the watch face.
While on the watch face, perform the calibration movement (figure 8).
The watch will eventually vibrate, signaling that the compass has been calibrated.
Go back to the compass widget to verify it has been calibrated.
I’ve performed this several times and every time I get the “phantom vibration.” My assumption is that some of us are perhaps in situations that cause the 9PP’s compass to reset often, and thus we get the phantom vibrations more often than others. I know for me, getting in and out of my car tends to mess with the compass calibration. Even a simple act like opening the refrigerator (with all those magnets on it) could reset the compass, triggering the background auto calibration and thus the phantom vibration.
@isazi @egika Is there a chance this could be verified by Suunto? Would this qualify as a bug? Although a minor inconvenience, it seems like something that could be an easy fix as it seems to only affect the 9PP.
Edit: You can perform an even easier verification. Simply bring a magnet close to the watch while on the watch face (locked or not). Then perform the figure 8 movement. You’ll get the phantom vibration once it calibrates, no need to check the compass widget. Checking the widget just verifies that the magnet reset the calibration.
