Why is there this small hole at the bottom of the smartphone? Know what will happen if it is removed

Noise Cancellation: Most Android smartphones have a hole at the bottom. However, hardly anyone knows why this hole exists and what is its use.

Noise Cancellation: The small hole at the bottom of the smartphone, which people often mistake for a microphone, is actually a "microphone grill".

This hole covers the "noise cancellation microphone", which helps reduce surrounding noise during calls. This microphone works in conjunction with the main microphone (which is usually on the front or top of the phone).

When you make a call, the noise cancelling microphone picks up the surrounding noise, and then uses special algorithms to separate it from the speech picked up by the main microphone. This technology helps you make clear and noise-free calls, especially in busy or noisy places.

If you remove the noise cancellation microphone grille, the quality of your calls may be affected. Surrounding noise will be heard more clearly in calls, which may make it difficult to carry on a conversation.

In addition, in some cases, removing the noise cancellation microphone may also cause problems with using other phone functions, such as the voice assistant.

It's important to note that not all smartphones have a noise-canceling microphone. If you're not sure whether your phone has one, you can check your phone's manual or the manufacturer's website.
