The way to easily know the phone radiation level.

How much memory is the camera, how many GB of battery life, or how many hours of battery backup - when we buy a smartphone, we are usually more interested in this information.

But there are many important features of the phone, which we are not thinking about. But after buying the phone, there is no way to deny the importance of those things in everyday use.

One such parameter on the smartphone is the radiation level. Invisible radio frequency waves are always emitted from the transmitting device in the phone. That wave emit does not harm our body at a certain level. But if this radiation level is excessive, then there is a deadly effect on our body.

That's why it's important to know whether radiation levels are safe on your phone, but it's important. The radiation of the phone is measured by the 'SAR value'. Each organization mentions the SAR value of the phone in the user manual.

But through this smartphone you can also know about this SAR value. How do you know? Go to the phone's dial pad and type '* # 07 #'. Then your screen will radiate the radiation levels of your phone.

This SAR value should not be more than 1.6 watts per kilogram, according to the telecommunication office guidelines of the Central Government. Do you have the radiation levels of your phone in the level specified in the government's direction? But take a look.
