Next-generation Samsung Galaxy Z Fold and Galaxy Z Flip devices to stick with existing biometric security methods

Samsung is months away from announcing either the Galaxy Z Fold4 or the Galaxy Z Flip4. Still, details about both devices continue to leak, mainly from supply chain sources. Recently, reports emerged that next-generation Galaxy Z devices would feature unchanged designs. Incidentally, the Galaxy Z Fold4 is rumoured to have better cameras and even an improved hinge design.

Subsequently, Business Korea reports that Samsung will not switch to in-display fingerprint scanners for this year's Galaxy Z models, unlike Vivo with its upcoming X Fold. Instead, Business Korea alleges that the Galaxy Z Fold4 and Galaxy Z Flip4 will retain their predecessor's capacitive fingerprint sensors. Samsung integrates these within their power buttons for reference, rather than as a dedicated button.

Reputedly, Samsung has considered switching to in-display fingerprint sensors. However, the company considers external fingerprint sensors more practical than their in-display alternatives, but only on foldable devices. By contrast, Samsung's flagship smartphones rely on in-display fingerprint scanners, like the Galaxy S21 Ultra and the Galaxy S22 Ultra. 

In comparison, Vivo has included two ultrasonic fingerprint scanners in the X Fold, as a leaked hands-on video has shown. Theoretically, this would allow you to unlock the X Fold regardless of which display you are using. Ultimately, this would increase production costs, just one of the reasons why the X Fold will cost nearly US$1,900 in China.
