Here's everything you need to know about the OnePlus 6T in-display fingerprint sensor
Less than 24 hours after sitting down with CNet for an exclusive interview regarding primarily the choice of a modern fingerprint-on-display feature over the beloved 3.5 mm jack, OnePlus CEO and co-founder Pete Lau is tackling the delicate matter yet again.
This time, we’re dealing with a “deep-dive” published on the company’s official forums, providing a look behind the scenes of the “Screen Unlock” technology development. Unsurprisingly, the story begins more than a year ago, as OnePlus originally tried (and obviously failed) to lose the conventional fingerprint reader of the 5T.
Although “much larger” in size than the “2nd generation model” found on the OnePlus 6T, the first attempt at a fast and accurate in-display unlock experience was not consistent enough. The “unreliable” module couldn’t be fixed through “intelligent software optimizations”, but this time around, “carefully tuned” hardware components are paired with a “wide array of software processes” for an experience naturally described as “fast, intuitive, and convenient.”
We’ll obviously have to wait and see for ourselves if that’s the case, with existing implementations on Vivo and Oppo phones widely considered imperfect but good enough... for the time being.
Like its fellow BBK-owned brands, OnePlus has no choice but to adopt an optical in-display fingerprint module, which may soon be eclipsed in both speed and accuracy by ultrasonic solutions rumored for Samsung’s Galaxy S10 and even the Huawei Mate 20 Pro.
For what it’s worth, we’re being promised “higher accuracy through extended use” with the Screen Unlock feature of the OnePlus 6T, which is certainly... something.
