When Samsung launched the Galaxy S5, they launched it with a heart rate monitor and while it still remains somewhat flakey in actual use, those out there who try their best to stay active will appreciate the ability to keep tabs on their BPM after they finish a run or a workout. Part of the now fairly comprehensive S Health app from Samsung, the heart rate monitor also made it to their wearables and with Samsung laying the groundwork for a big push in health and smart...stuff it comes as no surprise that the Galaxy Note 4 is to feature yet another different sensor. It was reported a little while ago that the Galaxy Note 4 is to feature a UV sensor (for ultraviolet light) and now SamMobile have been passed details on what this UV sensor will actually do.
The UV sensor will relay different levels of UV light recorded to the user in different levels ranging from 0 to 11 and above. With each level being two indices users will see readings of Low, Moderate, High, Very High and Extreme. Information will be given through the S Health app for different UV levels, for instance advice on wearing sunglasses in Low levels, with the advice getting more specific the higher up the ladder you get. Times on when to stay out of the sun and which factor of sun screen to wear will be given, as well as advice to keep away from reflective surfaces. With the UV Sensor, the S Health app on the Galaxy Note 4 is pegged to prevent skin cancer and careless sunbathing.
More than just simple prompts however, is an index of true or false statements regarding misconceptions about bright sunlight, for instance whether or not a suntan is actually healthy and that 80% of harmful UV rays can penetrate liberal cloud cover. All-in-all, the UV sensor will be geared to prevent skin damage and to better educate users who might not know much about how dangerous prolonged exposure to direct sunlight can be. The full list can be found over on SamMobile, and when we think about it, this actually makes a lot of sense. People will always take their smartphones on holiday with them, and if an app like this can prevent burned skin and damage to the skin then we're all for it. How well this UV sensor works in practice is of course something we'll have to wait to find out. Let us know what you guys think in the comments below.
