Galaxy S10: Most ground-breaking feature on new Samsung phone will be unusable with screen protector

Owners of Samsung's next flagship smartphone will not be able to be able to make use of its most exciting feature if they use a screen protector, according to the latest leak. The forthcoming phone – expected to be called the Galaxy S10 – is still a month away from being officially revealed, but a slew of leaks and rumours mean many of the key features are already known. One of the most highly-anticipated features is an in-screen fingerprint sensor, which will allow Samsung to make a full-screen device by not having to place the scanner separately at the bottom of the display or on the rear of the devive. The latest leak claims that placing a screen protector over the display will make this feature unusable. It was revealed in a tweet by Armadillotek, a US-based firm that manufactures "military grade" screen protectors for high-end Samsung smartphones.
