Surface Duo fingerprint security option now missing

My Surface Duo USB port crack around it and still under one year warranty however response from Microsoft Support is to contact them. So I contacted them but they are asking for $760 Canadian for shipping the unit for repair. This is a well know deficiency of the frame construction around the USB C-Port and they are well aware of the issue but they simply want to make more money out of their poor case design. The frame around the unit like all other similar cell phones should have been metal. This is my first Microsoft hardware purchase and unfortunately would the last one. I will start posting my comments where ever possible to advise others to stay away from purchase of such poor constructed unit with such high price.

I am having the same problem. Further, the fingerprint settings in the security settings is gone. I am very disturbed that this basic security feature just stopped. I've cleaned the sensor with IPA, I've restarted the Duo several times.

I guess my questions are:

1. Why did it stop working?
2. how do I turn it back on?

Thanks, for the suggestion. As I had mentioned the fingerprint setting was gone from the security settings. It reappeared after a few days. See conversation about moisture in the other part of this thread.

Thanks. The setting reappeared after a few days. I am not sure about this but I think I can correlate a few things about moisture, not a bike ride but running. :) Interesting.

Hello,

There are a few things that you can try here, first please clean finger print reader with a micro fiber cloth (it may already seem clean to the eye)

Next please restart the phone and test and if it still does not work go to settings, security, fingerprint and check to see if you have the ability to register a new fingerprint.
