With the introduction of the Samsung Galaxy Z Fold 3, the company was expected to use a fingerprint sensor under the display for this phone. But that did not happen, and Samsung integrated its fingerprint sensor with the power button on the side of the phone. However, according to LetsGo Digital, on March 31, the company filed a patent for a "clamshell phone with fingerprint recognition via a sensor under the display." It looks like it will likely be Samsung's Galaxy Z4 Fold.
The news was released a few days ago by the World Intellectual Property Organization (WIPO). But there seems to be a problem. The flexible display of clamshell phones when pressing the screen may make it difficult for the sensors below the display to read fingerprints. Samsung has provided a solution to this problem in its patent case. The company's solution was to place the fingerprint sensor on the phone in such a way that anyone who uses the phone in a folded or fully open form can be easily detected by the sensors below the display.
This will be done by placing the fingerprint sensor at the bottom left of the fold screen. This makes biometric authentication possible in either closed or open display. Between the two sensors is a small circuit board that connects to its main board. This case has been settled in South Korea. By the time the Galaxy Z Fold 4 launches next year, Samsung will likely be using a fingerprint sensor under the display in its clamshell phones.
Although all of this is rumored, Samsung is planning the Galaxy Z Fold Do not update 4 too much on hardware components. In other words, instead of updating the chip and camera as much as possible, Samsung will focus on providing more unique capabilities. Unique features of this phone include a selfie camera inside the display and support for a dedicated S-Pen. But these special features have been further optimized.
While Samsung is a world leader in clamshell manufacturers, it hopes to make these products more user-friendly as prices fall. Companies such as Google (whose Pixel Fold will be announced soon), Xiaomi, Vivo and Oppo could compete with Samsung in the production of clamshell smartphones. Many of these companies, however, source their clamshell displays from Samsung.
