We don't know if this one is going to be in the G5, but LG Innotek, the research arm of the company, just boasted it has developed an incredibly slim optical bio sensor, ready to go into smartphones and wearables. The leaked G5 does have some interesting-looking sensor overload on the back, but these could simply be the laser and infrared autofocus contraptions.
The tiny sensor is just 1 mm(0.04inches) thin, but still this module includes a photo diode(PD), 5 LEDs, and an integrated circuit(IC), allowing it to measure heart rates, stress indices, and even oxygen saturation levels. To top it all off, the optical sensor has lower power consumption yet higher measuring accuracy than existing comparable products, paving the way for slimmer phones and watches with stellar biometry.
