The Samsung Galaxy S22 fingerprint sensor is good. It’s certainly come a long way since the fingerprint reader on the Samsung Galaxy S10, which is enough to make some of us wish our Samsung Galaxy S9s were back.
But the latest reports suggest that the Galaxy S22 fingerprint reader may look dated compared to the rumored 2025. According to SamMobile, Samsung is currently developing an OLED display that may feature a fingerprint reader that is 2.5 billion times more secure than the single fingerprint reader in the current S22 series. This is based on an interview with ISORG CEO Dieter May on the website OLED-info.
Don’t let the “Sponsored Post” label stop you from seeing this information as a real possibility. While May cites Samsung‘s 2025 timeline as a competitive disadvantage for his own company’s now-available fingerprint readers, he seems confident that Samsung will have an in-display fingerprint reader capable of reading three fingerprints simultaneously by 2025. The technology might end up debuting on the Samsung Galaxy S26 or Z-series rather than the Samsung Galaxy S25 — if Samsung even keeps those naming conventions — but Samsung is already working on it anyway. Time will tell if it protects our phones as promised.
What makes this fingerprint reader 2.5 billion times more secure?
The simple answer is: mathematics. Samsung‘s rumored fingerprint reader scans three fingers at a time, compared to the single fingerprints that current mainstream readers can handle. While a single fingerprint reader is still very secure—according to May, the chance of false positives opening the phone is only 0.002 percent—adding two additional fingerprints changes that exponentially. Both May and Samsung Display did the calculations, and it turned out that false positives were 2.5 billion times less likely to unlock your phone.
We’ve seen some rumors about a shift away from single-fingerprint authentication methods. The latest Samsung Galaxy S23 Ultra display rumors suggest that Samsung’s next flagship Android smartphone will be upgraded to Qualcomm 3D Sonic Max, which uses its 17 times larger footprint to scan up to two fingerprints simultaneously. May also believes that while Samsung is currently her company’s main competitor, Apple may also adopt the technology, since a single fingerprint does not work with Face ID.
