Thought we were done already? Not yet! Last, but certainly not least, let's take a closer look at Huawei's new finger-reading tech.
The fingerprint sensor is made by Goodix and sits under the AMOLED panel, though Goodix markets the tech as an "in-display fingerprint sensor™".
The fingerprint flex cable contains a Goodix GM181 fingerprint controller.
The sensor isn't capacitive (like most familiar sensors such as Touch ID), but optical. This is reportedly similar to the sensor found in the new OnePlus 6T.
The sensor looks at your finger, which is illuminated by light from the display. Then the sensor uses the information it captures to create an image of the distinctive valleys and ridges of your fingerprint.
And underneath the display: a Synaptics S3718 touchscreen controller.
