so I finally got my S10+, then i bought tempered glass, everything works fine exept I can't unlock it, and I can't set a new finger. The guy at store told me I should make my finger print "stronger" and I don't know what he meant by that.Alredy tried with both gently and stronger push of finger....
Normal glass screen protectors dont work with the ultrasonic fingerprint sensor on the s10 plus. However a few do. I'd search the internet for specific branded protectors that work with it
On the box and everywhere Samsung has stated that most glass screen protectors won't work with the ultra sonic finger print scanner. Look for film ends or if you really really want glass I heard dome glass is really good and it works.
