This topic is really interesting and this habit is a guilty one we all have. We all get the mobiles in the toilet when we do our needs. But this makes germs spread faster which are transferred through our mobile phones when we touch them after wiping. We make more germs spread like salmonella and e.coli.
A good hygiene means no phone here. Experts say the phone gets contaminated with fecal dirt. This transfers bacteria fast and you touch the phone all day long, touch food after that and so on.
