The presentation of OnePlus 6T has brought us interesting changes to the OnePlus 6 from a few months ago, and besides that small notch or the absence of a headphone jack there is another differential novelty: the integrated fingerprint reader .
This technology is not new, of course: we have seen it as the Vivo X20 Plus UD started a trend that has been contagious to other manufacturers, but in the new OnePlus 6T the difference is that we are facing a device that has a greater potential scope . That could mean the definitive detachment of the fingerprint sensor integrated into the screen.
The OnePlus 6T, the last to bet on the reader integrated into the screen
There he explained how the difference in the Huawei model compared to that of Vivo – which used the ClearID technology from Synaptics – was the use of a Qualcomm chip that operated by ultrasound.
Other devices such as the OPPO FInd X or the Xiaomi Mi 8 Explorer Edition also had the Synaptic technology, which is based on the use of an optical sensor of which we also speak in Engadget a long time ago .
In the case of OnePlus 6T the supplier of the OnePlus 6T is still unknown chip, but everything points to will also be the Synaptics chip because OnePlus, Vivo and OPPO are under the umbrella of Asian electronics giant BBK .
No need to give up the fingerprint reader on the front
The appearance of almost frameless phones has caused manufacturers to make the fingerprint reader disappear from the front that often doubled as a start button. Many have relegated it to the back -if they did not put it there already- while others have decided to completely eradicate it to base biometrics on facial recognition.
For some users -and I include myself- having a fingerprint reader on the front is especially important and although facial recognition is an interesting alternative, some people prefer that much more direct action of put the strike on the screen to authenticate and unlock the mobile.
For that reason the sensors of footprint under the screen become a very interesting option for these users, since the devices do not lose that function and can combine it with other methods of unlocking . The only visible consequence (and not much) is the slight increase in the thickness of the device.
In the presentation event of the OnePlus 6T the firm has confessed how it began to work with this technology experimentally with the Oneplus 5T that was presented on November 18, 2017 , and although they did not include it with the OnePlus 6, they finally have decided to include it in the new OnePlus 6T a more complete device and that of course takes a step forward in this trend.
An important boost for this option
The adoption of this technology by the OnePlus 6T could be the definitive accolade to a trend that of course raises interesting alternatives.
It is true that the reader of Fingerprints have not disappeared from our smartphones' panorama, but the facial recognition or iris recognition systems have become increasingly important among high-end devices and may change that in the future to other product ranges.
However, the inclusion of these integrated sensors in this model could be very relevant. Unlike other devices that have already been included as those of Xiaomi, Vivo, OPPO or Huawei, the OnePlus smartphone has a greater reach among the general public both by price and global distribution and that could show that these readers can indeed be a solid option in the future.
It's time to see the behavior of these sensors, which at least in the Mate 20 Pro left of course could not be compared with the behavior of the conventional physical reader : we have to place the finger in a very specific way and the response time is not comparable in these devices in our tests.
In the OnePlus 6T, however, it has been revealed that the unlock time is only 0.34 seconds and if that speed is real and joins an accurate recognition even without support the finger “to perfection”, we could have a very interesting future candidate.
As the proposals of Synaptics and Qualcomm could soon also come out a competitor. A patent from Samsung discovered just a few days ago tells us about a system that also placed a fingerprint sensor under the screen, but with a singular difference: the entire screen will be a fingerprint sensor ] thanks to a co-processor that would be in charge of controlling that part without “bothering” the smartphone's CPU.
It seems therefore that this type of solutions are the order of the day, but to know if the trend consolidates we will have to wait to see the performance in the OnePlus 6T and, of course, what happens in that first half of next year in which it is likely that other manufacturers adopt this type of technology.
