A new study by researchers from the University of Oregon titled “Mobile phones carry the personal microbiome of their owners” and published by PeerJ, looked at the biological connection between people and their phones.

Contents of the swabs from the fingers and phones were then analysed using statistical methods.
They had three main findings.
