TL;DR
- The Samsung Galaxy S26 series includes a toggle to improve fingerprint accuracy.
- This feature lets you scan a previously registered fingerprint to improve unlocking accuracy.
- This is a long-overdue move and comes after other workarounds, like making two separate scans of the same finger.
Smartphones first offered in-display fingerprint scanners in 2018, but the technology was slow and unreliable at first. Fast-forward to 2026, and many flagship Android phones have ultrasonic in-display fingerprint sensors for fast and accurate unlocking. However, the Samsung Galaxy S26 series adds another welcome option if you’re having problems with your fingerprint unlock.
