Galaxy S9+ Fingerprint scanner not working

[Android Central Question]

I have got my S9+ for a week now and over the past 3 days I am having an issue with the fingerprint scanner. When unlocking the device I get a message saying "The fingerprint scanner is not responding. Try again later."
When I go into setting and go to fingerprint settings I a message saying "An error has occurred with the fingerprint sensor. If this message appears repeatedly, restart your device."
This has happened many times ove the past 3 days. On other forums I see people are restoring phone to factory settings and so on. Is there any other quick fix without losing data?

Guys this is crazy but the sensor actually doesn't work because your finger might be cold. Rub your finger on or pants for friction and then it will work.
