One of the OnePlus 6T’s headline features is Screen Unlock, its in-display fingerprint scanner. The Chinese firm kicked up an almighty fuss around it ahead of the phone’s launch, but cool as it is, we were slightly underwhelmed by it when we actually managed to get our hands on the 6T.
As we wrote in our review: “The feature sounds cool, but it isn’t perfect8230; The [OnePlus 6]’s rear-mounted solution was undoubtedly faster but it added seams to the design and it would seem that OnePlus considered that a problem, or simply antiquated. The new concealed optical sensor is definitely a touch less reliable than its predecessor, but it feels very cool to use.”
“Every time a user successfully unlocks the phone with their fingerprint, the sensor also records areas of the finger that weren8217;t registered in the initial fingerprint setup stage. This fingerprint data is then added to the data the phone already holds, making it more complete. So, every time the in-display fingerprint sensor is used, it gathers more data about the user’s fingerprint. This means that over time, the phone will unlock even faster.
“The sensor’s algorithms are also able to figure out when the user’s fingerprint is different than usual – if their finger is wet or if they have a cut on it, etc. In these cases, once the phone is successfully unlocked, the algorithms add this new fingerprint data to the existing data to improve unlock speeds under these conditions in the future.”
