Firmware refers to the applications and operating system that control how a Samsung Smartphone operates. It is called firmware rather than software to highlight that it is very closely tied to the particular hardware components of a device.
Software includes sets of instructions that allow a variety of inputs from the user. Firmware is a specific type (or subset) of software that is designed to act as the intermediary between the software and hardware or for the operation of single-purpose embedded systems, such as printers or routers.
Typical examples of devices containing firmware are embedded systems (such as traffic lights, consumer appliances, and digital watches), computers, computer peripherals, mobile phones, and digital cameras. Firmware is held in non-volatile memory devices such as ROM, EPROM, or flash memory.
Go to [Device Settings] > [Settings Table]. Check the "Firmware Version" in the Settings Table.
Firmware is a type of software that is etched directly into a piece of hardware. It operates without going through APIs, the operating system, or device drivers—providing the needed instructions and guidance for the device to communicate with other devices or perform a set of basic tasks and functions as intended.
