A factory reset will restore your device to its original manufacturer settings. It removes installed applications, user accounts, personalized settings, and system changes made after purchase. If you choose the full reset option, it also deletes personal files such as documents, photos, and downloaded software.

This process is commonly used to fix serious software problems, remove viruses or malware, improve performance, or prepare the device for resale. After completion, the device starts like new and requires initial setup again.
