LG G7 might come with an advanced iris scanner
An unearthed patent by LG revealed that the Korean company is preparing an advanced iris scanner that might arrive just in time for the next flagship the LG G7. It will not only unlock the device, but also help you make protect sensitive information.
The iris scanner checks the biometric characteristics of the eye and sets up with a light screen and a dark screen, since the iris changes in size, depending on how much light gets to it. Then the sensor will check what are you looking at and if you are the owner of the phone, the sensitive app will be available for opening.
Iris Scanner usually works with infrared light, but LG has developed a camera which can switch from infrared to a regular one. This might mean fewer cameras and sensors on the front, which also will lead to a smaller top bezel.
