That’s fine; just don’t use it while driving.
Here’s an irony. One day, while on the way to help a relative, my phone rang. It had fallen to the floor and in case it might be important, I pulled off the freeway, so I could find a parking lot to return the call. I waited for the oncoming traffic to go past, so I could get onto the service street. I had pulled forward a little and was about to pull all the way out into traffic when the car behind me rearended me because she had not been paying attention.
