What does factory reset mean?

A factory reset is a process that restores a device, such as a smartphone or computer, to its original manufacturer settings. This means that all personal data, applications, and custom configurations are erased, returning the device to its initial state as it was when first purchased. Factory resets are often used to troubleshoot issues, clear personal information before selling a device, or resolve persistent software problems. It's important to back up important data before performing a factory reset, as it cannot be recovered afterward.
