Your phone is disgusting - not because it's old, or doesn't have a fingerprint reader, but because it's covered in bacteria.
Luckily Corning, who make the near-ubiquitous Gorilla Glass which many top smartphones are made with, have a solution.
Their new type of glass has a built-in antibacterial material which kills nasties with the destructive power of... silver.
Microbes are killed on contact with toxic silver, and the result is a smartphone which is arguably cleaner and perhaps a bit healthier.
The downside? This hasn't actually be approved for use yet, in the USA let alone in the UK, and once it's ready it will be a while before it's fitted to phones - the first use is with workspace furniture, according to Gizmodo.
Still it's pretty intriguing - check out the video to find out how it works.
