Is there a way to make the speaker icon less sensitive?

[cellulartalk]

My wife has the 6S+ and often when she's on a call her cheek will rub against the speaker icon and activate speakerphone. I thought she was pressing the phone to hard against her cheek, but I was on a call with her phone the other day and the same thing happened to me. Is there a setting...
