Smartphone has so much penetrated in our daily life that now no one can think of without it. Excessive use of smartphone may cause health problems but if you are even using less a smartphone with bad SAR, that is most dangerous.
Here SAR stands for Specific Absorption Rate which is a measure of the amount of radio frequency energy absorbed by the body when using a mobile phone.
