iOS 16.4 adds voice isolation for calls & more.

Apple has launched the new iOS 16.4 update, which features new emojis, voice isolation for cellular calls, and web push notifications.

The new update adds 31 new emojis, including the long-awaited pink heart, two pushing hands, a Wi-Fi symbol, and more.

The voice isolation feature prioritises the user's voice and reduces ambient noise around them during cellular calls.

iOS developers can send notifications to users when the user has pinned a web application to their Home Screen.

This feature is useful for new Twitter rivals that don't have iOS versions of their apps yet.

Users can update to the latest version by navigating to Settings, General, and then Software Update.

The voice isolation feature is accessible through the Control Center while on the call.

The update is available for iPhone 6S and newer models.

The iOS 16.4 update provides several bug fixes and improvements.
