The UVLEN phone flash sterilizer is very suspicious.

Well this is awkward. A company is about to launch a product that they claim will turn your phone's camera flash into a germicidal lamp by virtue of a little filter that slides out in front of it.
Their marketing material suggests that they filter out the unwanted wavelengths and only let the 222nm wavelength through.
That's not possible, as your phone's flash does not put out any light in the 222nm wavelength or even any significant ultraviolet at all.
If they tried to imply that their filter converted the wavelengths of your white flash to 222nm that would be an outstanding scientific breakthrough that would open up many new exciting technologies. But it's very unlikely.

They imply that they are a Google certified company, with a link to a google maps factory location, which means nothing.

My opinion of this is that it's a scam. And I'd be very wary of downloading the matching app.

It's no great surprise that the Daily Mail has published what is in effect an advert for this. They have very low editorial standards.
