In short: Chinese smartphone manufacturer OnePlus released a new video teaser for its upcoming OnePlus 6T Android flagship, having unveiled a short clip that displays an "unlock the future" tagline, hinting at one of the new key selling points the company will be introducing with its next product – an in-display fingerprint reader. The video that can be seen below doesn't reveal much more than that and there's still no official word on when exactly will the OnePlus 6T be officially announced, though most industry insiders are in agreement that its launch is likely taking place on October 17.
Background: OnePlus already confirmed its final 2018 handset will be equipped with an in-display fingerprint reader but did so in a rather vague manner, without revealing any concrete details about the authentication setup it's planning to use. Seeing how extremely fast fingerprint readers have been touted as the main selling points of its devices for several years now, questions remain about how the company will manage to maintain that feature while still delivering an in-display scanner. All under-screen readers that have been commercialized so far are of the optical variety, with their implementations being noticeably slower than what traditional sensors are capable of delivering. The rear-mounted fingerprint scanner of the OnePlus 6 was capable of unlocking the device in 0.2 seconds but its successor is expected to be significantly slower than that, save for an unlikely scenario wherein OnePlus becomes the world's first manufacturer to commercialize cutting-edge ultrasonic readers that Samsung and Huawei are presently said to be working with.
Impact: OnePlus's pursuit of a truly uniform smartphone design has now led it to opt for an in-display reader that will likely be a compromise between functionality and form, though the company should improve the authentication performance with next year's OnePlus 7 or OnePlus 7T that may feature a more advanced, ultrasonic sensor instead of the first-generation optical one.
