The "Home Button" is a physical or virtual button found on many electronic devices, such as smartphones and tablets. Its primary function is to return the user to the main screen or home interface of the device, allowing easy access to apps and settings. In the case of Apple devices, the Home Button was traditionally a physical button located at the bottom of the screen. However, newer models, like the iPhone X and later, have replaced it with gesture-based navigation, while Android devices may have a virtual Home Button on the screen or as part of a navigation bar.
