Earlier this year, Samsung released the Galaxy S10 series which comes with an ultrasonic fingerprint sensor. While this fingerprint reader is top-notch, it does not work well with a tempered glass screen protectors. Many users can not use a smartphone without a screen protector, so what’s the solution? Accessory makers use a liquid adhesive to create a stronger seal between the protector and display. While this seem to work perfectly for some users, try not to buy a ∼$3 screen protector.
Gizchina News of the week
A Galaxy S10 user recently got a $3 ‘gel screen protector’ off eBay. However, he realized that after using the protector, any fingerprint could unlock the phone. According to Samsung, the case is under investigation. Nevertheless, the company considers this issue to be related to the cost of the screen protector – ∼$3. Recall that Samsung earlier warned Galaxy S10 owners against unofficial screen protectors.
Samsung’s ultrasonic fingerprint reader works by sending sound waves at the user’s finger and reflected waves are read. However, standard glass protectors create a small gap between the finger and the display. This reduces the effect of the fingerprint sensor. In the era of full-screen devices, ultrasonic on-screen fingerprint sensors are actually a good solution. However, they are by no means perfect. Nevertheless, users will have to come to terms with the fact that only plastic protectors seem to allow ultrasonic fingerprint readers to work without issues.
So if I find someone’s S10, I’ll know how to unlock it.
Suspect the fingerprint was set with the protector on. So that’s the pattern its is matching
Instead of blaming the screen protector which does its work , samsung should be working on why this glitch happens. As j. Cooper said, one just need $3 to unlock an s10.
So what ur telling me if somebody gets there s10 pinched all they have to do is buy a cheap screen protector to unlock it that’s crazy samsung that’s down to u no one els
