Surprisingly, Apple released the iOS 16.4 update on Tuesday, which brings several minor improvements to the iPhone's operating system.
iOS 16.4 brings new features such as web push notifications, voice isolation for cellular calls, emojis, credential counting, and more.
To update to the latest iOS 16.4 update from Apple, iPhone users need to go to their Settings and go to General and click on Software Update to update their smartphone.
"This update introduces 21 new emoji and includes other improvements, bug fixes, and security updates for iPhone," Apple said.
The 21 new emojis include a shaking face, the long-awaited pink heart, two pushing hands, a Wi-Fi symbol, and more.
