The Galaxy Z Fold 4: a fingerprint sensor may be installed beneath the dual display

Admin

When the Galaxy Z Fold 3 was first unveiled a few months ago, there was no mention of a fingerprint scanner beneath the display. Samsung, on the other hand, appears to be planning to incorporate this technology with the Galaxy Z Fold 4. According to LetsGo Digital, Samsung submitted a patent for a “folding electronic device featuring fingerprint recognition through part of the display” on March 31.

The World Intellectual Property Organization recently revealed patent information on two-way patent scanners (WIPO). Because of the higher flexibility of folding gadgets, implementing a fingerprint scanner is a complex undertaking. As a result, Samsung has avoided using this technology in its clamshell phones, but it appears that the Korean giant has now solved the problem.

While the screen is open, the biometric sensor is positioned on the external display and can be used. Both modes are detected by an electronic board located between the two screens. The study took place in South Korea in 2020, but we won’t know if Samsung will deploy the technology until the Galaxy Z Fold 4 is released.

The Korean behemoth is presently the world leader in clamshell phones, and it is believed that in the next few years, the ultimate price of these devices will drop, making them more accessible to customers. Other firms’ interest in creating clamshell phones is increasing competition in this market, probably leading to more reasonable prices.

A recent report has shown that Google Pixel Fold will most likely be released shortly. Other firms interested in establishing a major presence in this market include Xiaomi, Oppo, and Vivo. Of course, it’s worth mentioning that Samsung is the maker of most foldable displays. There is still a long way to go until Samsung unveils the Galaxy Z Fold 4, and by then, additional information about Samsung’s next clamshell phone will be available.
