Firmware is a type of software that is embedded in hardware devices, such as iPhones. It controls the low-level operations of the device, such as how it interacts with the operating system and other hardware components. Keeping your iPhone’s firmware up to date is important for ensuring that your device is running smoothly and securely.
There are a few different ways to check the firmware version of your iPhone. One way is to go to the Settings app and tap on “General.” Then, tap on “About” and scroll down to the “Firmware Version” section.
