Both the regular Galaxy S10 and S10+ come with an under display, ultrasonic fingerprint sensor. An ultrasonic fingerprint sensor uses soundwaves to detect a 3D image of your fingerprint. The sound waves bounce back from the surface of your finger which allows the system to analyze the ridges and depths of your fingerprint.

Ultrasonic fingerprint sensors vary from the capacitive fingerprint sensor on the Galaxy S9/S9+ and the S10e. Capacitive fingerprint sensors only measure your fingerprint in 2D, whereas ultrasonic sensors can map a clearer image via 3D.

The ultrasonic fingerprint is also durable enough that it still functions with scratches on the screen above the sensor. However, it doesn’t function once the screen above the sensor has been cracked.

Another major advantage of ultrasonic fingerprint sensors are that they work in harsher conditions. An ultrasonic fingerprint sensor will be better at reading a fingerprint even though it’s dry, dirty or wet.

However, there have been several complaints and issues regarding the ultrasonic fingerprint sensor on both the Galaxy S10 and S10+ on multiple forums such as Reddit, XDA Developers and Samsung Community. Check out some examples below:

For those of you, who are having issues regarding unlocking your S10 with the ultrasonic fingerprint display, you should definitely try the series of steps mentioned below. We found these steps by doing a lot of research on what users are saying about this problem.

  • Ensure your device has the latest update
  • Search and enable touch sensitivity from the settings
  • Remove all your saved fingerprints

Remove Fingerprint

  • Add your fingerprints

Add fingerprint

  • Start with the middle of your thumb. Not the edge of the thumb. The part that is about half cm inside. Press that portion and don’t do much of a sideways motion till you reach about 80 percent. Now use the edge of the thumb and try to move the edge a bit to reach 100 percent.
  • Add the same finger again. This time start with edge and try to get to 80 percent without much motion. Then use middle of thumb to reach 100 percent.
  • Do the same for other thumb. Also don’t register your thumb in vertical position. Just register the way you would hold a phone and try to scan your thumb. Close to horizontal may be at 5-10 degrees.
  • You may be required to press a bit hard while registering your finger but this is not needed to unlock the phone.

Swapping out the pre-installed Screen Protector

If you would like to add a tempered glass screen protector to your new Samsung Galaxy S10 or S10+, please ensure that you get the right type. The ultrasonic fingerprint scanner only works with liquid glue tempered glass.

You have to get a tempered glass which uses liquid glue and is cured via UV rays. There are 2 products which work with the ultrasonic scanner which have been listed below.

Of course, you can always go the other way, and just find a tempered glass screen protector which has a cutout at the location of the ultrasonic fingerprint sensor.

Update 1 (March 14)

Samsung has listed out use cases in which users may face issue with S10’s fingerprint sensor, and has also said the accuracy of the sensor will be made better through updates in future.

There can be many occasions where users find the fingerprint scanner doesn’t work well, for example, when you are in a dry environment, or when your finger skin is really dry, or when you have a scratch on your fingerprint

The accuracy has been improved through the first update of software recently just in one week since the launch, and we will continue providing updates to make the scanner work better
