With the launch of Samsung Galaxy S8 In the realm of technological discussions, it's common to hear about potential design and usability changes. Among the most talked-about innovations, one stands out as particularly specific and striking: The fingerprint reader could be located on the back of the device, altering a hallmark of the Galaxy family.
The fingerprint reader has been ... displaced
While it seemed clear from the rumors that Samsung's physical Home button was going to disappearIt was also said that the reason was the bet on an optical fingerprint reader under the glasslocated on the front. However, leaks suggest that, even with that technology, the sensor it would move to the back sectionThis decision would reopen the perennial debate about the best location: front for direct table access and payments, or rear due to ergonomics when holding the mobile phone, as is the case in terminals like the Google Pixel.
If confirmed, we would be facing a significant visual and functional change In the Galaxy S8, they eliminated the iconic button that had identified Samsung for years and adopted a cleaner aesthetic. This move would impact daily interaction: unlocking when taking the phone out of your pocket It feels very natural with the index finger behind it, but it also involves challenges such as Avoid accidentally touching the camera if the sensor is too close. The key will be in the module's design and in a good haptic feedback that guides the finger without looking.
Samsung Galaxy S8, on the way to a screen without bezels
The compelling reason for moving the reader from the front is clear: maximize the use of the front surface by the screenA physical button, or even an optical sensor integrated into the bottom, It reduces the usable space on the panel. and makes it difficult to achieve a virtually frameless designBy freeing up the front, Samsung could offer a more immersive and modern experience, with gesture navigation or virtual keys.
Furthermore, for a fingerprint reader to be reliable, the reading surface must be of sufficient sizeReducing its size excessively to fit the sensor onto the front would affect accuracy and speed, something the user would notice immediately. Therefore, a rear-mounted position, well-insulated and with differentiated textureIt makes sense: it guarantees speed, minimizes false rejections, and allows a truly starring screen design.
How to set up the fingerprint reader on the Galaxy S8
If you choose to use the fingerprint as main method (or alongside iris and facial recognition), setup is simple. Make sure your finger is clean and dry for a reliable capture and follow these steps:
- Opens Settings from the notification bar (gear icon) or from the app drawer.
- Accede to Lock screen and security and enters Fingerprint scanner.
- For security reasons, the system will ask you set or enter a PIN, pattern, or password.
- Record the fingerprint by pressing your finger down several times. varying the position and angle to improve recognition.
- Once saved, you can add more fingers and activate fingerprint usage for Samsung Pass y Verifying your Samsung account, streamlining logins and authorizations.
Tip: Record two fingerprints of the same finger with slight variations. Improves the success rate without compromising security and speeds up unlocking on a daily basis.
Sensor gestures: useful and easy to activate
The rear fingerprint reader isn't just for unlocking. Samsung incorporates gestures on the fingerprint sensor that facilitate everyday tasks:
- Go to Settings and enters Advanced functions.
- Locate and activate Gestures for the fingerprint sensor.
- From that moment on, you can Slide your finger across the sensor to lower or raise the notification bar, a particularly convenient feature on elongated screens.
These gestures contribute speed and ergonomics with one hand, avoiding extending your thumb all the way to the top. If you get used to it, they become an indispensable shortcut.
For those who prefer alternatives, the Galaxy S8 allows you to combine fingerprint scanning with iris recognition y facial recognitionThey are quick and convenient options; using multiple methods increases the flexibility depending on the context: mask or gloves, low light, or need to unlock without lifting the phone from the table.
Moving the reader to the back fits with the trend of prioritizing the screen and hand comfort. With good sensor placement, a precise fingerprint configuration and gestures activatedThe Galaxy S8 offers a streamlined and consistent biometric experience with its almost bezel-less design, while maintaining alternatives such as iris and face scanning to suit each user.
