What is a phone’s SAR value and how to find it

A SAR value shows how much energy the body absorbs from a phone’s radio waves and is measured in W/kg. Phones on sale must stay below the legal limit. On many Android phones the *#07# code, and on iPhone the legal section in Settings › General, shows the SAR value.

Cep Market Repair TeamIn Kadıköy since 2006
Key points
  • SAR shows the radio energy the body absorbs.
  • The unit is W/kg; a lower value means less absorption.
  • In Europe the limit for head and body is 2 W/kg.
  • On many Android phones *#07# shows the SAR information.
  • Using earphones reduces exposure.

03To reduce exposure

  1. Earphones. Use earphones or the speaker on long calls.
  2. Signal. With weak signal the phone transmits harder; call from a spot with good signal.
  3. Distance. Do not keep the phone right by your head in bed.

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
