Take your phone out of your pocket...
…because it’s not safe! Smartphone manuals say we should keep phones 10 millimeters away from our bodies! Because radiation exposure may exceed FCC standards if you keep your phone on your body – or press it to your head as you use it. I know that defeats the purpose of using it as a phone – but I guess that’s why there are headsets, earbuds, and speaker-phone-mode.
