We all use smartphones for one or two hours a day
If you are sitting idle at home then this time can go up to 4 to 5 hours. Even a person working in an office is always active on his smartphone because through this, his work is being monitored and updates related to it are being taken. We all have been using smartphones for years, but do you have complete information about their hardware? We are saying this because there are many parts of mobile phones about which people are not aware. Today we are going to tell you about one such part.
Often there is a small hole behind the rear camera of the smartphone. This hole may be slightly smaller or larger in different models. Do you know why the company has given this hole and what is its function? If you are thinking that it has been given only to maintain the design, then it is not so at all. This hole is given for a special purpose which improve our mobile experience.
This small hole does a big job
This small hole at the back of the smartphone is a noise-cancellation microphone. That is, when you talk to someone on a smartphone, this microphone works to reduce the sound coming from behind you so that your voice reaches the other person. A microphone is also provided in the lower part of the smartphone where the charger is installed, through which your clear voice reaches the person. The noise cancellation microphone present at the back works to reduce the background noise completely so that there is no disturbance in the call.
