New Delhi, Jan 17 (ANI): A new study has recently provided a deeper insight into how filthy mobile phones are that people use in their daily life. The study revealed just how much bacteria is on the phone and it's pretty gross, an online portal 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.
