The Samsung Galaxy S21 series has been making waves in the smartphone market since its release, with its impressive features, sleek design, and top-notch performance. However, one question has been on everyone’s mind: does the Galaxy S21 have a fingerprint sensor? In this article, we’ll dive deep into the world of biometric authentication and explore the answer to this question.
The Evolution Of Biometric Authentication
Before we dive into the specifics of the Galaxy S21’s fingerprint sensor, let’s take a step back and look at the evolution of biometric authentication. In the past, fingerprints were the primary method of biometric authentication, but with the rise of facial recognition and iris scanning, the landscape has changed. Samsung, in particular, has been at the forefront of this evolution, introducing features like iris scanning in the Galaxy S8 series and facial recognition in the Galaxy S10 series.
The Rise Of In-Display Fingerprint Scanning
In recent years, in-display fingerprint scanning has become a popular trend in the smartphone industry. This technology allows users to scan their fingerprints directly on the screen, eliminating the need for a physical fingerprint sensor. The first smartphone to feature in-display fingerprint scanning was the Vivo X21, released in 2018. Since then, many manufacturers, including Samsung, have adopted this technology in their flagship devices.
The Galaxy S21’s Biometric Authentication Features
So, does the Galaxy S21 have a fingerprint sensor? The short answer is yes, but with a twist. The Galaxy S21 series features an in-display fingerprint sensor, which uses ultrasonic technology to scan fingerprints. This technology uses high-frequency sound waves to create a 3D map of the user’s fingerprint, providing a more secure and accurate authentication experience.
The Benefits Of In-Display Fingerprint Scanning
There are several benefits to using in-display fingerprint scanning on the Galaxy S21. For one, it allows for a more seamless user experience, as users can simply place their finger on the screen to unlock their device. Additionally, in-display fingerprint scanning takes up less physical space, allowing for a more compact design and a larger screen-to-body ratio.
Security And Accuracy
One of the primary concerns with in-display fingerprint scanning is security and accuracy. Samsung has addressed these concerns by using a more advanced ultrasonic technology, which provides a higher level of accuracy and security compared to traditional fingerprint scanning methods. The Galaxy S21’s in-display fingerprint sensor also features advanced anti-spoofing measures, making it more difficult for hackers to bypass the system.
Comparison To Other Biometric Authentication Methods
The Galaxy S21’s in-display fingerprint sensor is not the only biometric authentication method available. Here’s a comparison of the different methods:
| Method | Advantages | Disadvantages |
|---|---|---|
| In-Display Fingerprint Scanning | More convenient, more secure, and takes up less physical space | May not work well with certain screen protectors or gloves |
| Facial Recognition | Fast and convenient, works well in low-light conditions | Less secure, can be bypassed with a photo or video |
| Iris Scanning | High level of security, works well in low-light conditions | May not work well with glasses or contact lenses |
Conclusion
In conclusion, the Galaxy S21 does have a fingerprint sensor, but it’s not a traditional physical sensor. Instead, it features an advanced in-display fingerprint scanning system that provides a more convenient, secure, and accurate authentication experience. While there may be some limitations to this technology, it’s clear that Samsung has made significant strides in biometric authentication.
So, if you’re considering purchasing a Galaxy S21, rest assured that you’ll have a robust and reliable biometric authentication system at your fingertips.

Does The Galaxy S21 Have A Fingerprint Sensor?
The Galaxy S21 series does not have a traditional fingerprint sensor. Instead, Samsung has opted for an under-display fingerprint scanner, allowing users to unlock their device by placing their finger on the screen. This technology is still relatively new, but it has shown promise in providing a seamless and convenient biometric authentication experience.
While some may be skeptical about the effectiveness of this technology, Samsung has made significant improvements to the under-display fingerprint scanner in the Galaxy S21 series. The scanner uses advanced algorithms and machine learning to detect and recognize fingerprints, providing a fast and accurate unlocking experience.
How Does The Under-display Fingerprint Scanner Work?
The under-display fingerprint scanner in the Galaxy S21 series uses optical technology to capture fingerprint images. This is achieved through a series of tiny lights and sensors embedded beneath the display screen. When a user places their finger on the screen, the sensors detect the fingerprint patterns and transmit them to the device’s processor for analysis.
The scanner is incredibly fast and accurate, thanks to the advanced algorithms and machine learning capabilities. These algorithms can even adapt to changes in the user’s fingerprint over time, ensuring that the scanner remains effective and secure.
Is The Under-display Fingerprint Scanner Secure?
Samsung has implemented various security measures to ensure that the under-display fingerprint scanner is secure and protected from potential threats. The scanner stores fingerprint data in a secure area of the device’s memory, and all data is encrypted to prevent unauthorized access.
Additionally, the scanner is designed to prevent spoofing attacks, where an attacker tries to use a fake fingerprint to gain access to the device. Samsung has also implemented various anti-spoofing measures, such as detecting the vitality of a fingerprint, to ensure that the scanner is only responding to genuine fingerprint input.
Can I Use The Fingerprint Scanner With A Screen Protector?
In general, it is recommended to use a screen protector specifically designed for the Galaxy S21 series to ensure compatibility with the under-display fingerprint scanner. Some screen protectors may interfere with the scanner’s ability to detect fingerprints, so it’s essential to choose a protector that is optimized for this technology.
Samsung has partnered with various manufacturers to offer screen protectors that are compatible with the under-display fingerprint scanner. These protectors are designed to allow the scanner to function accurately and efficiently, providing users with a seamless and convenient biometric authentication experience.
How Accurate Is The Under-display Fingerprint Scanner?
The accuracy of the under-display fingerprint scanner in the Galaxy S21 series is impressive, with Samsung claiming that it can recognize fingerprints with a high degree of accuracy. In ideal conditions, the scanner can accurately detect fingerprints in a matter of milliseconds.
However, as with any biometric authentication technology, the accuracy of the scanner can be affected by various factors, such as the cleanliness of the screen, the condition of the user’s fingers, and environmental conditions. Nevertheless, Samsung has made significant improvements to the scanner’s accuracy and reliability, making it a reliable option for unlocking the device.
Can I Use Other Biometric Authentication Methods With The Galaxy S21?
In addition to the under-display fingerprint scanner, the Galaxy S21 series also supports other biometric authentication methods, including facial recognition and iris scanning. These methods can be used in conjunction with the fingerprint scanner or as an alternative, providing users with multiple options for securing their device.
Facial recognition uses the device’s front-facing camera to detect and recognize facial features, while iris scanning uses a dedicated iris scanner to detect the unique patterns in the user’s iris. Both methods are highly secure and convenient, providing users with a range of biometric authentication options.
Is The Under-display Fingerprint Scanner Available On All Galaxy S21 Models?
The under-display fingerprint scanner is available on all Galaxy S21 models, including the Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra. Samsung has standardized this feature across the entire series, ensuring that all users can enjoy the convenience and security of this advanced biometric authentication technology.
Regardless of which Galaxy S21 model you choose, you can rest assured that you’ll have access to the under-display fingerprint scanner, providing a seamless and convenient way to unlock your device and access sensitive information.
