Galaxy S8 fingerprint reader

[Mad Mordigan]

I'm having an issue with my fingerprint reader. It doesn't work. Well at least not always. Does anyone else have this issue? If so, is there a fix?

Make sure the sensor window is clean. If it is, you may have an intermittent sensor. (Don't try replacing it yourself. If it's not in warranty, have a repair shop do it.)
