The sensor will display UV information in the included S Health app. SamMobile’s report goes into intricate detail about the different UV index levels that the sensor can detect.

Hopefully it will work better than the heart rate monitor on the Galaxy S5, which is really quite finicky. The idea that a UV sensor would be helpful on a phone isn’t too far-fetched. There are already products like the Netatmo ne that measures your exposure to the sun sync with an app on your smartphone to alert you when it’s time to go inside. It’s also a heavy sell to the Korean market, which is more concerned with avoiding exposure to the sun than we are in the U.S. Since Samsung is a Korean company, it tends to make many of its product decisions based on its home market. Samsung is expected to debut Galaxy Note 4 later this summer, either before or during IFA 2014 in Berlin, Germany. ’ll be there covering a majority of the gadget announcements, so stay tuned.
