kamruun The fingerprint sensor in the display is an important part of the current hole-punch screen design used by most Android vendors. But there are exceptions to rules: folding phones like the Galaxy Z fold and flip. Samsung puts the fingerprint sensor on the side of the handset, and is reported to keep it on the Galaxy Z 4 and Flip 4 this summer It might seem like a downgrade compared to ordinary Android smartphone experience. The Android device maker prefers fingerprint sensors for 3D face authentication, while Apple prefers the last one.
The face ID is responsible for the big notch at the top of the iPhone. But there is no need for notch on an Android phone. Fingerprint sensor sitting under the screen on the Android handset, allowing vendors to offer display design all screens without removing extra security that can be offered by biometric Fold phones are more complex, because they offer users two experiences. Whether we see the fold or flip design, each device has the main folding display and a secondary cover screen outside. Where did you put fingerprint sensors to serve users at any time?

The folded screen may seem like the display you use the most, especially in clamshell like the Galaxy Z Flip 3. But putting a fingerprint sensor under a foldable display means the user will continue to open the handset to unlock. It can be a problem for cellular payments on devices such as Flip 3.
Then, there is a case to put a fingerprint sensor below the device cover display like folds. But it will make it inaccessible to use when the main screen is opened. After all, fingerprint sensors don’t just let you unlock the phone. It also authenticated you in the application when you use it.With that thought, it was not a surprise to hear that the Galaxy Z Fold 4 and Flip 4 will remain in the predecessor’s fingerprint sensor. It according to Korea’s business, which claims that Samsung has considered using sensors in the display for upcoming cellphones. However, Samsung decided not to move forward with the plan.
Samsung has a patent that describes a double fingerprint sensor in a folding screen like the Galaxy Z Fold 4. The sensor will sit well below the cover screen and below the folding screen. That way, users will have access to fingerprint sensors no matter how they use fold handsets. However, such design will come at an additional cost. Samsung must use two sensors, and they will occupy additional space on the phone.
With all that in mind, the installation of fingerprint sensors in the side button makes it more sense for the Galaxy Z 4 folding and flip 4. The same blog says that the vivo x fold launched next week will display ultrasonic fingerprint sensors on display on both cover and folding screen.
