The OnePlus 6T‘s in-display fingerprint sensor is blazing fast and also happens to be one of its standout features, but it appears that Screen Unlock becomes even faster over time. In an official blog post, OnePlus explained that every time users put their finger over the sensor, it not only recognizes the fingerprint pattern to unlock the smartphone, but also records some more fingertip regions that were not in the database during the initial set-up.
In addition to recognizing previously unregistered fingerprint patterns and adding them to the database, the Screen Unlock algorithms can also identify when the fingertip is wet or has a scar from a small cut. This irregularity is also logged in the database, so the next time you try to unlock the OnePlus 6T when your thumb is wet, the unlock speed will be slightly faster than the first time.
