Note 4 is the first phone with UV sensor, protecting beachgoers since 2014

On the sensor side, however, Samsung has something completely new to offer us  - namely an UV sensor, for the first time on a mobile device. It comes adding to an already huge stable of mobile and biometric sensors, like an improved fingerprint scanner and heart rate sensor. The UV piece will be used to measure the sun’s ultraviolet radiation, and be incorporated to prevent users from burning their skin, bringing premature wrinkles and moles, and increasing the risk of melanoma.

There are a five UV index levels: Low, Moderate, High, Very High and Extreme, and the S Health app will issue tips for tanning and sun exposure, based on the place and time you are using the sensor to measure the radiation rating. For the measurement to happen, one will have to maintain more than a 60 degree elevation angle against the sun with the back of the sensor. What do you think about this new addition to Samsung's smartphone sensor stable?
