People baffled after discovering the purpose of small hole under phone charging port

Enhancing call clarity

The secondary microphone captures and amplifies sound waves. This helps ensure that your voice is transmitted clearly during calls.

It is especially important in noisy environments where background noise could otherwise interfere with your conversation.

By improving audio clarity, this microphone enhances the quality of your phone calls.

Supporting noise reduction

By working alongside the primary microphone, this secondary microphone helps reduce environmental noise.

This technology, known as “dual microphone noise reduction,” ensures that only the audio from your call is transmitted to the listener, improving overall call clarity.

Improving audio recording.
Beyond phone calls, this microphone also aids in recording clearer audio for videos and sound-related applications like video recorders, VLCs, and sound recorders. Its presence ensures that the audio captured is as clear as possible.

Maintaining phone functionality.
Blocking or interfering with this microphone can hinder its performance, leading to issues such as reduced audio clarity during calls and recordings.
