Playing with the Note 4's UV and SpO2 sensors

Playing with the Note 4's new UV and SpO2 sensors
Samsung's Galaxy S5 came with a dedicated heart-rate monitor, and while the benefits of this additional sensor remain dubious at best, the recently-announced Galaxy Note 4 and Note Edge have something new to try and wow us with: dedicated UV and SpO2 sensors!

So, what exactly do these two new sensors bring to the table? Well, the UV sensor is pretty self-explanatory: when you're outside and point the sensor (which is positioned on the back of the Note 4) at the sun, it'll show you the current level of UV radiation and whether or not that's good for your health. Unfortunately, we were only able to test it indoors, so pointing it at the hall's lighting naturally resulted in an extremely low UV reading. On the other hand, giving the SpO2 sensor a try returned a result of 97%! We actually don't know if this is good or bad, but hopefully everything's OK. Check out the new sensor in action in the following video!
