What is a Factory Reset?
A factory reset restores your device to its original settings by completely erasing all data, including apps, contacts, photos, videos, and system settings.
This process returns your device, such as the Samsung Galaxy S9, to the state it was in when first unboxed.
It's important to back up any essential data before performing a factory reset, as this action is irreversible.
Factory resets are useful for:
- Improving device performance,
- Removing malware or viruses,
- Preparing your phone for resale,
