by

When you’re ready to sell your Galaxy S20, ensuring your personal data is completely wiped is crucial. This protects your privacy and prevents any potential misuse of your information. Following best practices can make the process secure and effective.

Why Wiping Data Is Important

Before selling or giving away your Galaxy S20, removing all personal data is essential. This includes photos, messages, app data, and account information. Failing to do so can expose your private details to the new owner or malicious actors.

Preparing Your Device

Before wiping your device, back up any important data you want to keep. You can use Samsung Cloud, Google Drive, or transfer files manually to your computer. Once backed up, sign out of all accounts to prevent activation lock issues later.

Backing Up Your Data

  • Open Settings on your Galaxy S20.
  • Navigate to Accounts and backup.
  • Select Backup and restore.
  • Choose your preferred backup method (Samsung Cloud, Google Drive).
  • Follow on-screen instructions to complete the backup.

Signing Out of Accounts

  • Go to Settings.
  • Tap on your Google account and select Sign out.
  • Repeat for Samsung account and any other linked services.
  • Remove SIM card and SD card from the device.

Performing a Factory Reset

The most effective way to wipe all data is through a factory reset. This restores the device to its original settings and deletes all personal information.

Steps to Factory Reset Your Galaxy S20

  • Open Settings.
  • Scroll down and select General management.
  • Tap Reset.
  • Select Factory data reset.
  • Review the information and tap Reset.
  • Enter your PIN or password if prompted, then confirm.

Wait for the reset process to complete. The device will restart and display the initial setup screen, indicating all data has been erased.

Additional Security Tips

To further secure your data:

  • Remove any linked accounts from your device before resetting.
  • Disable Find My Mobile or similar services.
  • Ensure the device is fully charged before starting the reset.
  • Perform the reset in a secure environment.

Final Checks Before Selling

After the reset, verify the device displays the initial setup screen. Check that no personal data remains. Once confirmed, your Galaxy S20 is ready for its new owner.

Following these best practices ensures your personal information remains protected and your device is clean for the next user. Proper data wiping is a responsible step in the selling process.
