Device Motion Event running even when my phone isn't moving
I am working on my first app and the code below is not working as expected and the documentation is a bit sparse.
if(window.DeviceMotionEvent){
window.addEventListener('devicemotion', function(eventData) {
console.log('event listener running');
});
console.log('device motion event triggered');
}
The code above is meant to measure acceleration excluding gravity. The issue is that without moving my phone, the entire if statement runs once and the event listener itself runs repeatedly. If I am understanding the code above correctly, none of it should run unless i move my phone.
Is this by design or is there an issue? If so what can I do to address it? I am running the code in Chrome DevTools which I've remotely connected to a google pixel 1.

Your deivce's accelerometer's readings change rapidly in very small amounts even when the device is static.
You'll have to write some code to filter those small changes. I don't know javascrript, but the process is like this:
- Log the x,y,z values to the console for a while when the device is static.
- find the maximum value and add 10% - this will be your threshold.
- In your eventListener store the values of the first reading as a reference.
- Every time that your listener is triggered - check the delta from the reference - if it is bigger then the threshold - your device has moved.
- Update the values of the reference, so each time you will compare the current reading to the previous one.
