Fingerprint scanner iPhone 8 may be located below the power button
At the moment there is no doubt that the iPhone 8 with a screen which will occupy almost the entire front panel will lose the Home button. It was under her previously occupied by the fingerprint sensor.
The sources said that Apple may abandon the use of the fingerprint scanner in the iPhone 8, or to place it under the display surface. Now we have another version referred to in a registered Apple patents.
Based on this information, the fingerprint scanner of the iPhone 8 will be under the power button, which can be located in the usual place on the top panel. The button can be covered with a protective glass, perhaps a sapphire.
However, Apple also has patents in which the fingerprint sensor is located under the surface of the screen.
