OnePlus phones have always had one core selling point: they’re as powerful as the latest flagship Android phones, yet cost hundreds of dollars less. That winning combination made the OnePlus 6 and 5T two of our top recommended phones of the past year. The new OnePlus 6T mostly continues that trend, but this time it’s bringing some cutting-edge innovation with it.
Instead of putting your finger on a fingerprint button or pad on the back or edge of the phone (or maybe under the screen), the OnePlus 6T has a biometric scanner built right into the bottom third of its display. A fingerprint icon pops up if you move the phone, you place your thumb on it, the logo lights up under said thumb, then the screen unlocks and you’re in. It’s ever so slightly slower than a standard Touch ID-style fingerprint sensor, like the ones on older iPhones (and every other Android phone).
It does take a little practice. At first, unlocking my 6T was a nightmare. I scanned my two thumbs, and it was taking me close to two full seconds to unlock the phone. I didn’t understand why. After a day or so, I decided to rescan my thumbs, but keep them at the same angle (from the side) the entire time. After that adjustment, unlocking has been incredibly speedy.
I chalk my early troubles up to the new kind of sensor. Instead of using capacitive touch, like a regular fingerprint reader, OnePlus stuck an optical fingerprint reader under the AMOLED screen. It’s invisible to the naked eye, but since it’s a visual reader, it’s possible that me scanning my thumbs from varying angles had a negative impact on my unlock speed.
