Yes, the Samsung Galaxy S10 does have an ultrasonic fingerprint sensor.
According to available information, the Samsung Galaxy S10 and the S10+ models are equipped with a secure Ultrasonic Fingerprint Scanner. This advanced sensor technology is integrated directly into the front screen of the device, allowing users to unlock their phone by simply placing their finger on a specific area of the display.
Understanding Ultrasonic Fingerprint Technology
Unlike traditional capacitive fingerprint sensors, which use electrical capacitance to create an image of your fingerprint's ridges and valleys, ultrasonic sensors use high-frequency sound waves.
Here's how it generally works:
- Emission: An ultrasonic pulse is emitted from the sensor beneath the screen.
- Reflection: This pulse hits your finger placed on the screen's surface.
- Reading: The waves bounce back, and the sensor reads the echoes. Since your fingerprint ridges and valleys reflect the sound waves differently, the sensor creates a detailed 3D map of your unique fingerprint pattern.
- Verification: This 3D map is then compared to the stored fingerprint data to authenticate the user.
This method is generally considered more secure and can work even if your fingers are slightly wet or dirty, compared to optical or some capacitive sensors.
S10 vs. S10+ vs. S10e Fingerprint Sensors
It's important to note that while the S10 and S10+ share the same ultrasonic technology, the S10e model utilizes a different type of sensor.
| Model | Fingerprint Sensor Type | Location |
|---|---|---|
| Galaxy S10 | Ultrasonic | On the front screen |
| Galaxy S10+ | Ultrasonic | On the front screen |
| Galaxy S10e | Capacitive | On the Power key |
As stated in the reference: "The sensor on the S10e is intuitively located on the Power key, making it easier than ever to unlock your phone." This means the S10e uses a more traditional, physical fingerprint reader integrated into the side power button, not the in-display ultrasonic technology found on the S10 and S10+.
Benefits of the S10's Ultrasonic Sensor
The ultrasonic fingerprint sensor on the Galaxy S10 offers several advantages:
- Enhanced Security: Creates a detailed 3D map, making it harder to spoof.
- Convenience: Located discreetly under the display, offering a seamless look.
- Performance: Can often read fingerprints even with slight moisture or grease.
In summary, if you have the standard Samsung Galaxy S10 model (or the S10+), it is indeed equipped with an ultrasonic fingerprint sensor located beneath the display.
