Galaxy Z Fold 4 May Feature A Dual-Sided Fingerprint Scanner

Galaxy Z Fold 4 Could Characteristic A Twin-Sided Fingerprint Scanner

Samsung has patented one thing actually attention-grabbing. The corporate was awarded a patent for a dual-sided (under-display) fingerprint scanner, which it could use on the Galaxy Z Fold 4 subsequent yr.

This patent surfaced on the World Mental Property Workplace (WIPO), and was noticed by Letsgodigital. It was submitted again on March 31, nevertheless it was revealed on October 7.

Now, there isn’t any assure that this fingerprint scanner will make it to the Galaxy Z Fold 4. That’s only a wild guess, although. As we’re nonetheless distant from that launch, so Samsung could have sufficient time to implement it.


If not, the Galaxy Z Fold 5 may characteristic it, however it might be good to see it within the Galaxy Z Fold 4, that’s for positive. The Galaxy Z Fold 3 does have a fingerprint scanner, nevertheless it’s a side-facing one.

Many individuals nonetheless favor capacitive fingerprint scanners
