When you’re ready to sell your Galaxy S21 Ultra 128GB, it’s essential to wipe your data properly to protect your privacy. This guide walks you through the steps to ensure your personal information is securely erased before handing over your device.
Preparing Your Galaxy S21 Ultra for Data Wipe
Before wiping your device, back up any important data you want to keep, such as photos, contacts, or documents. You can use Samsung Cloud, Google Drive, or transfer files to your computer. Once backed up, you can proceed with the reset process.
Performing a Factory Reset
The most effective way to wipe your Galaxy S21 Ultra is through a factory reset. Follow these steps:
- Open the Settings app on your device.
- Scroll down and tap on General management.
- Select Reset.
- Tap on Factory data reset.
- Review the information and tap Reset again.
- Enter your PIN, password, or pattern if prompted.
- Confirm by tapping Delete all.
The device will restart and begin erasing all data. This process may take several minutes. Once complete, your Galaxy S21 Ultra will be restored to its original factory settings.
Additional Security Tips
To further ensure your data is unrecoverable, consider the following:
- Remove your SIM card and SD card before selling.
- Perform a manual sign out of all accounts, such as Samsung and Google.
- Disable Factory Reset Protection (FRP) by removing your Google account if possible.
- Check that the device no longer displays your personal information after reset.
Final Checks Before Selling
After completing the reset, turn on the device to verify it boots to the initial setup screen. Confirm that no personal data remains. Once satisfied, your Galaxy S21 Ultra is ready for its new owner.
