Whenever we buy a smartphone, we want to know everything about it. Turn on the screen of the phone to get information about the display, look at the camera placement from the front and back, and get complete details about the SIM slot, memory slot, earphone jack, USB and loudspeaker.
You know everything about what is in it, but have you ever noticed a small hole in the bottom of the phone, right next to the charging port? Do you know what this hole does or what it is used for?
You may not have noticed this hole yet, but you will do it now. It neither works as a flash, takes photos, or has any button. In such a situation, today, through this article of ours, we are telling you about this hole.
Why is there a small hole
The small hole below the smartphone’s charging port is the noise-cancelling microphone. Yes, you heard it right. We will also tell you how this microphone works.
