It seems that OnePlus wants to make the most of its deal with T-Mobile by making OnePlus 6T a device that would be hard to resist. The latest development has confirmed that the phone will come with an in-screen fingerprint scanner, a feature that has only been seen on select Vivo devices and the Huawei Mate RS Porsche Design so far.

The company has substantiated the rumours itself that alleged that the successor to OnePlus 6 will have an in-display fingerprint scanner. Dubbed the Screen Unlock by OnePlus, the feature will help the company trip bezels and eliminate the extra steps associated with a rear-mounted fingerprint sensor.
