This is a reminder in your cellphone that advise you keeping the phone away from your ear for 5 seconds when you are going to answer the phone. Most of us know that the cellphone radiation is harmful to us ,but we use it everyday. We can only get a small amount of radiation from our cellphone every time we use it, but we will use it all our lives. According to the scientific experiments, we would receive the highest radiation when we start to answer the phone, which is about ten times more than that In standby mode. So, if we can skip this dangerous period of time, we can avoid most of the radiation.
