Smartphone Tips: Today’s smartphones have many design elements that we never pay attention to. One of them is a small hole near the charging port. Many people see this and assume that it is meant to remove the SIM tray, whereas the truth is something else. Due to this small misunderstanding, sometimes the phone can get damaged.
It is important to understand the difference between the SIM tray and this hole.
The SIM tray hole is usually on the side of the phone and is accompanied by a clear cutout or tray. At the same time, the small round hole near the charging port at the bottom of the phone is not connected to any tray. Trying to suppress it with SIM PIN can prove to be a big mistake.
What is this hole actually used for?
This small hole is actually given for the microphone. Phone calls, video recordings, voice notes and voice assistants require clear and crisp sound to function properly. Your voice reaches the phone through this microphone.
What harm can happen by inserting SIM PIN?
If someone accidentally inserts a SIM pin or any sharp object into the microphone hole, the delicate parts inside may get damaged. This can cause problems like loss of sound during a call, poor audio in the video or the microphone turning off completely.
Why do many phones have more than one small hole?
Often people get more confused after seeing why there are two or three small holes in the phone. Actually, different microphones are for different purposes. One main microphone is for calls while the other is provided for noise cancellation to reduce background noise.
How is it protected from water and dust?
This microphone hole is not completely open. There is a special mesh and water-resistant layer inside it which prevents dust and water from entering inside. This is the reason why light moisture does not cause immediate damage to the phone.
