smartphones available from leading manufacturers, and staying current with the newest features and technology can be quite a challenge. While we are preoccupied with figuring out what is state-of-the-art regarding this app or that integrated feature, there may be elements of our phone’s physical design that we merely overlook. For example, did you spot the tiny hole adjacent to your phone’s charging port?

Regardless of whether you’re using an iPhone or an Android device, the minute hole located near the USB-C (or Lightning) port is usually a microphone. When you are making calls, activating a voice assistant, or capturing a voice memo, your phone depends on its integrated microphone to perform these functions and more. In most scenarios, this isn’t the sole mic your phone may possess either, as typically one or two additional microphones are situated elsewhere for a more comprehensive audio experience.
