3. How to back up your data before a factory reset

Before performing a factory reset, back up your data to prevent permanent loss. Use Smart Switch to transfer data to a PC or another device.

1. Download and install Smart Switch PC on your computer.

4. Open Smart Switch on your PC and select Backup.
5. Review your backup files and confirm the process.

Note: Smart Switch does not transfer hidden files or files in the Secure Folder. Disable security settings to access these files.

4. How to remove a Google account from your Samsung Galaxy device

Disconnecting your Google account prevents Factory Reset Protection (FRP) from locking your device after a reset.

1. Go to Settings > Accounts and backup > Accounts.
2. Select the Google account you want to remove.
3. Tap Remove account and confirm the action.
4. Repeat for all linked Google accounts.

Important: If you forget your Google account password, visit a Samsung service center for assistance.

5. How to perform a factory data reset

A factory data reset erases all personal data, apps, and settings from your Samsung Galaxy device.

2. Navigate to General management > Reset > Factory data reset.
3. Review the warning message and tap Delete all.
4. Enter your PIN, password, or pattern to confirm.

FRP is a security feature that requires Google account authentication after a factory reset. It helps prevent unauthorized access to lost or stolen devices.

- FRP was introduced with Android 5.1 (Lollipop).
