But if you are constantly handling your phone it will reduce the value of frequent washing/sanitizing of hands, since anything you do get on your hands will transfer to your phone.
Although, I don’t know what the numbers look like for transferring virus when a touch occurs—e.g. if we look at a path like “handshake → touch phone → [wash hands] → touch phone → touch face”, how much of the virus is left after four sequential touch events like that? Perhaps this kind of secondary contamination is not actually a huge deal? I have no idea.
A powder called Glo Germ, meant to visualize germ spread, was still visible to the naked eye after 8 handshakes (but not 9) in an informal experiment by YouTuber Mark Rober. ( https://youtu.be/I5-dI74zxPg?t=346 )

I guesstimate the deal is not negligible.
