One of the most prevalent rumours about the Samsung Galaxy S10 is that it would come packing an in-display fingerprint scanner, following in the footsteps of the likes of Huawei and OnePlus. It's been rumoured for a long time, but so far Samsung has kept its mouth shut about the possibility. Now, though, some hidden code seems to confirm all the rumours and leaks were true.
The code in question was dug out of Samsung Pay by XDA Developers, mentioning the S10's 'Beyond' code name and how the app will authenticate a user's identity without a typical physical fingerprint scanner. Specifically the code says "enlarge bottom layout for Beyond in-display FP scanner" which suggests that the "payment flow window" will shift upwards if there's an in-display scanner present - thereby giving someone room to scan their digit.
It doesn't confirm which S10 models will have the fancy new scanner (though leaked images have already shown us that it'll probably be all of them.), but it is an indication that Samsung is aware of different challenges users may face with the in-screen biometric tech. With constant competition from Google Pay, it obviously needs to make sure Samsung Pay is as seamless on the S10 as it is on all the older devices.
