Wouldn't a hands-free option increase the exposure, since it means the phone doesn't even have to be taken out of the pocket?
> Almost all smartphones, he said, have power sensors — also known as proximity sensors — designed to detect when the device is touching or extremely close to a person. When that occurs, the phone is supposed to reduce power, decreasing radiofrequency radiation.
That's the first I heard of that. I thought the proximity sensor was only to power off and lock the screen when the phone is held to the ear, to prevent the ear touching the screen from pressing on-screen buttons - which is why, on all phones I've seen, the proximity sensor is right next to the speaker.
- dwd 7y agoI received a text message from my provider recently with a link to tips for reducing exposure. My instant thought was legal has seen a problem. You don't go suggesting ways to minimise exposure if it's a non issue and as safe as we've always been told. I guess step one to reduce legal liability is put the onus of safety onto the user so they share some of the responsibility, or so you can announce that there is a problem but we've been warning you for years. When told to don't panic, it usually means you have a fair reason to.

- cesarb 7y agoThe headphone cable is used as a receive-only antenna for longer-wavelength signals like digital TV and FM radio. Using it is required for these features, and won't increase the exposure since it's receive-only.
