Melbourne: A new study has recently provided a deeper insight into how filthy mobile phones are that people use in their daily life.
Students from the University of Surrey revealed just how much bacteria is on the phone and it's pretty gross, News.com.au reported.
Bacteria use all sorts of things as vectors in order to transmit - insects, water, food, coughs and sneezes, or sexual contact.
Many of the phones showed the biggest and clearest blotch of bacteria growing around where the "home" button was.
Most of the bacteria is harmless but disgusting. And some disease-carrying bacteria such as the Staphylococcus aureus has turned up in previous years when the university conducted the experiment.
