Time and using phone in the Toilet

It has been said by many doctors that using phone in the toilet is harmful to the health. 

Microbes enjoy living in environments like a phone because it's warmth makes them thrive. 

And after washing your hands, you'd pick up your phone and the microbes on it. 

Still the temptation is too much, why use 10min. sitting and watching when I have mails and messages to respond to for example.

What I sometimes do is use the phone in my left hand. It is better and safer to use it that way. 

I hope you've learned. 

Any other suggestions about this?
