I wrote a native service app to collect all sensor data from my Galaxy Watch Active 2 and save them in a file at 50Hz. However, I could only get the accelerometer and gyroscope data logged but no other sensors such as magnetic sensor, orientation sensor, etc. Is this a problem on these sensors in my watch or is this a known issue that these sensors just don’t work on Active 2?
hey even i am facing the same issue in a different way
I am trying to make a face in watch face studio for my galaxy watch 4 to have a compass type index like in the pro analogue watch face
reference in pic. also finding a good compass index
check if you have all the permission and if they are granted…
ps. watch active 2, and others with tizen os, does not have magnetic sensor

there is no tag available for compass on wfs, only on native

My Watch5 Pro does not have that compass it has the indexes but the poles (N E S W) are missing 
That is a nice looking feature.
As @dect pointed out this is not available for WFS because not all Wear 3 devices have a compass.

Hey what about the magnetic sensor in Watch active 2? Is it also not available? I see it in the documentation!
In the Tizen documentation it looks like it has been in since Tizen 2.3 but in the Samsung Specs it says
- Sensor Type
Type
Accelerometer, Barometer, Gyro Sensor, HR Sensor, Light Sensor, ECG Sensor

Its right there
apply the analogue pro watch face
press it to get the edit/customize menu
there would be a customization for index it
there are 2 of them one is simple and the other one with compass poles which uses magnetic sensor data and acts like a compass index
You are correct, and I stand corrected. I didn’t try customizing it. Someone else pointed this out to me.
