Galaxy M17 5G delivers reliable and fast biometric security

The Samsung Galaxy M17 5G features a side-mounted fingerprint sensor integrated into the power button, designed for quick and secure unlocking. Positioned conveniently on the frame, it allows users to unlock the device naturally while holding it. This design ensures easy access whether the phone is placed flat on a table or picked up from the side.

In real-world testing, the fingerprint sensor performs smoothly and consistently. It recognises registered fingerprints almost instantly, typically unlocking the screen in under half a second. The sensor’s placement means users can both wake and unlock the device with a single press, making the process effortless during daily use.

During multiple unlock attempts, the sensor maintained a high accuracy rate, with very few failed reads. Even when fingers were slightly damp or oily, the Galaxy M17 5G still managed to register successful unlocks in most cases. This level of reliability adds confidence for users who rely heavily on fingerprint security.

Facial recognition is also available as a secondary biometric option. Using the front camera, the system works well in bright indoor and outdoor conditions. However, in low light or dim environments, facial unlock tends to slow down or occasionally fail to detect, prompting users to fall back on the fingerprint reader.

When comparing both methods, the fingerprint sensor clearly stands out for speed and reliability. Unlocking the phone while picking it up feels seamless, with the screen turning on and opening to the home screen in one motion. Unlike under-display sensors found in higher-end models, the side-mounted reader avoids lag or sensitivity issues.

Testing the unlock speed under various conditions showed consistent performance. Even after several hours of standby, the Galaxy M17 5G woke up and unlocked in a fraction of a second once the sensor was pressed. The only minor delay observed came from the unlock animation, not the sensor itself, making the overall experience fluid and dependable.

Samsung’s software integration also helps optimise recognition accuracy over time. The fingerprint system learns subtle variations in the user’s touch, improving detection with repeated use. The phone supports up to four stored fingerprints, allowing flexibility for users who switch hands frequently or share the device occasionally.

Security-wise, the biometric data is processed locally within the device’s secure enclave, ensuring that stored fingerprints or facial data remain protected. The system complies with Samsung’s Knox security platform, adding an extra layer of trust for privacy-conscious users.

In practical UK use, such as commuting, working, or travelling, the sensor’s speed and placement make it ideal for quick access without compromising security. Whether unlocking in transit or in low light, the sensor consistently delivers fast results, making it suitable for both casual and professional users.

Overall, the Galaxy M17 5G’s fingerprint and facial recognition systems offer a strong balance of speed, accuracy, and convenience. The side-mounted fingerprint sensor is quick, dependable, and secure, giving it an edge over many competitors in its range. For UK users seeking reliable biometrics, this device performs exceptionally well in daily use.
