What Does Factory Reset Mean?
Factory reset is the term used to describe the removal of user data from an electronic device and restore it back to factory settings. It is a software restore and aims at resetting the software found in the device to original manufacturer settings. A factory reset can be used to resolve some software issues associated with the device or simply to wipe all user data from a device.
Techopedia Explains Factory Reset
A factory reset effectively removes all the user data, third-party applications, associated application data and settings found on the device. It is similar to hard drive reformatting in a computer. However, data present on other media, such as a secure digital card, is not affected by a factory reset. A factory reset can be accomplished in many ways, and mostly depends on the electronic device. In some cases, the factory reset option is available in a service menu on the device, whereas in some other cases, a special button is pushed or a complete re-installation of the device software might be needed.
