http://www.techradar.com/news/lg-g7-rumored-to-come-with-an-advanced-iris-scanner >Up until now LG hasn't followed Samsung's lead by including an iris scanner in its phones - both the LG G6 and LG V30 were fingerprint-only - but a newly unearthed patent submitted by LG suggests that could change in 2018 with the arrival of the LG G7. >The patent, as spotted by LetsGoDigital, is for biometric authentication through an iris scanner as normal, but the filing mentions a few extra tricks. The sensor will adjust its reading based on ambient light, for a start, to allow for variations in pupil size and to make sure you can always use the scanner no matter what the lighting conditions.
