Detect device rotation/orientation in Ionic 4 without rotating app

Is it possible to detect rotation in an Ionic4 app without actually rotating the entire app?
I’m using this:

I’d like to enter some callback on device rotation, not necessarily rotating the entire app. If I lock orientation, i lose the screenOrientation.onChange() emits. If I unlock rotation, my screenOrientation.onChange() emits, but the app also rotates. Attempting something like this:

this.screenOrientation.unlock();
this.screenOrientation.onChange().subscribe(ev => {
        this.screenOrientation.lock(
          this.screenOrientation.ORIENTATIONS.PORTRAIT_PRIMARY
        );
        // Do other stuff
});

makes the rotation jump between the two which looks bad. Been fighting this for a while, any ideas are appreciated
