Toybox.SensorHistory.getOxygenSaturationHistory strange samples

Yes, this looks to be an issue between the VM and the FW.

Thank you for the confirmation. I suppose we have to wait for a firmware update. 

I've been adding more to this app, and what I do see, is the max value can have a really bad value, and it seems that all samples are 0 on an actual device, But still checking on that.

Not looked at this before and to be honest, I usually don't even have the sensor on, but threw together a really simple app.  It shows the time, current value from Sensor, and the most recent from SensorHistory. On a 945 Sensor shows what I see in the widget, and SensorHistory is 0.000000 but I'm not sure how often a value is saved to history.  I've only been running for 5 minutes. Here's the code as I suspect you may not be looking at the correct thing:

    function onUpdate(dc) {
    	dc.setColor(Gfx.COLOR_BLACK, Gfx.COLOR_BLACK);
    	dc.clear();
    	dc.setColor(Gfx.COLOR_WHITE, Gfx.COLOR_TRANSPARENT);
    	var clockTime = System.getClockTime();
    	dc.drawText(width/2,20,Gfx.FONT_SMALL,clockTime.hour.format("%d")+":"+clockTime.min.format("%02d")+":"+clockTime.sec.format("%02d"),Gfx.TEXT_JUSTIFY_CENTER);
    	
    	var si=Sensor.getInfo();   	
    	dc.drawText(width/2,50,Gfx.FONT_SMALL,""+si.oxygenSaturation,Gfx.TEXT_JUSTIFY_CENTER);

		var iter=SH.getOxygenSaturationHistory({:period=>30,:order=>SH.ORDER_NEWEST_FIRST});
    	var min=null;
		var max=null;
		var cur=null;
		if(iter!=null) {
			min=iter.getMin();
			max=iter.getMax();
			var sample=iter.next();
			cur=sample.data;
    	}
    	dc.drawText(width/2,80,Gfx.FONT_SMALL,""+cur,Gfx.TEXT_JUSTIFY_CENTER);
    }

And her's the sim (I used a va4 in the sim and playing back simulated data): /resized-image/__size/320x240/__key/commentfiles/fb5d84b10a5745448a7a45dafc1faa43-5f0a3292-9daf-48e8-9168-e638f7e86748/pastedimage1598824178196v1.png
