"Maximizing iPhone Call Quality: Hidden Features and Tips"

Apple has introduced a new feature called Voice Isolation to iPhone cellular calls that prioritizes the sound of the user's voice over other sounds in the surrounding environment. To enable this feature, users must be on an active cellular phone call and swipe down from the top right corner to open Control Center on iPhone, then tap on the Mic Mode button and choose "Voice Isolation" from the available options. This feature is available on iOS 16.4 or newer and can help to improve the clarity of voice communication on iPhone calls and reduce other sound distractions from the environment.
