According to a report by SamMobile and Galaxy Club, it is possible that the Galaxy S9 and S9+ could be sporting some sort of an "environmental sensor." It should be noted that it's way too early to be predicting anything about the Galaxy S9 and this is just guesswork at best. Nevertheless, they do have the patent and while a patent doesn't necessarily guarantee a feature in the future, there's always the possibility that it might make an entrance in one of the next smartphones.
The sensor itself has something to do with detecting air quality around the user and its readings are not just copied information from the internet. Based on the smartphone's own detections, it will likely instruct the user regarding how to take appropriate precautions. Check out the patent drawings above and let us know what you would think if this feature made it onto Samsung's next flagship smartphone.
