Samsung Galaxy A70 Safety Tip: Turning Off Wi-Fi and Bluetooth Reduces Radiation.

This SAR chart reveals how turning off Wi-Fi and Bluetooth on your Samsung Galaxy A70 can significantly reduce your exposure to radiation. Our SAR comparison chart shows that by simply turning off these transmitters, you can lower the RF radiation exposure to your head by 70.8%, and you can lower exposure to the body by 43.2%, when considering these differences between cellular-only (Wi-Fi/Bluetooth OFF) and simultaneous use exposure (Wi-Fi/Bluetooth ON), a wise way to reduce excessive phone radiation is to tap off unnecessary transmitters when not in use. Additionally, when using your phone as a hotspot, turning off Bluetooth can reduce your exposure by up to 100% according to the FCC SAR report for device number A3LSMA705FN.
