Future Galaxy smartphones could feature an 'Environmental Sensor'

In polluted cities—Beijing and Jodhpur, for example—the so-called Environmental Sensor will analyze atmospheric conditions and instruct users to affix their pollution mask if it sees fit. It'll also be useful for those traveling abroad, as they'll be able to view details about air quality live on their handset to decide what precautionary measures to take.

Remember: It's only a patent

As this is, of course, a patent, there's a chance the technology will never see the light of day. There's clearly a demand for it on smartphones launched in the Asian market—and seeing as the firm has already found a way to make it fit in a handset, it would be rash to assume that it isn't planning on bundling it on board the Galaxy S9, though that's far from confirmed.
