Every cell phone has fine print user instructions that are about radiation limits.
All cell phones have clear instructions in their manuals to distance the phone away from your body. This is because when a phone is placed in contact with your body, the radiation that will penetrate into your body could be at levels that exceed government recommended limits.

Phones are radiation tested with a space — a separation distance — between the phone and a body dummy, and that is why there are these fine print instructions. Most people assume phone radiation tests are conducted in the same ways that people use these devices in positions touching the body, however, phones are not tested touching the body.
