Alas, that is the only information we were given, and it's rather vague at best. Also, we're still no closer to learning what this UV sensor will be used for. It could allow for better auto brightness when the phone is used outdoors, helping Samsung's continued attempts to improve the outdoor visibility of its Super AMOLED displays, or it could be used to warn users when, you know, the sun is too hot, which would probably make a nice addition to the S Health app.
However, we will have to wait for more concrete details to find out just what purpose the UV sensor serves, and whether it changes the way we use a smartphone in any meaningful way.
