What Happens If You Do a Factory Reset on Your Android Phone?

A factory reset is a powerful tool for refreshing your Android device, but it’s important to understand its implications.

Here’s what happens when you perform a factory reset:

Erases All Data

  • Personal Data: All your data, including contacts, messages, photos, videos, and files stored on the device, will be deleted. Make sure to back up any important data before proceeding.
  • Apps and App Data: Any apps you’ve installed and their associated data will be removed. This includes game progress, login credentials, and personalized settings.

Resets System Settings

  • Settings and Preferences: All system settings and preferences will return to their original state. This means Wi-Fi settings, wallpaper, and customized settings will be lost.
  • Accounts: All accounts, such as Google, email, and social media accounts, will be removed from the device.

Restores Pre-installed Apps

  • Default Apps: The device will revert to its factory state, meaning only the apps that came pre-installed on the device will remain. Any updates to these apps will also be removed.

Removes Malicious Software

  • Malware and Viruses: A factory reset can help eliminate malware, viruses, or any unwanted software that may have been installed without your knowledge.

7 Things to Do Before a Factory Reset

Preparing for a factory reset is crucial to ensure you don’t lose important data and to make the process as smooth as possible. Follow these steps to get ready:

1. Backup Your Data

  • Google Backup: Use Google Backup to save your contacts, calendar events, app data, and settings. You can enable this by going to “Settings” > “System” > “Backup” and turning on “Back up to Google Drive.”
  • External Storage Device: Transfer important files, photos, and videos to an external storage device such as a USB drive or external hard drive.
  • Cloud Service: Utilize cloud services like Google Drive, Dropbox, or OneDrive to upload and save your essential files and documents.

2. Log Out of Accounts

  • Google Account: Go to “Settings” > “Accounts” > “Google” and log out of your Google account to prevent any issues with reactivation post-reset.
  • Other Accounts: Ensure you log out of any other important accounts, such as email, social media, and banking apps.

3. Remove External Storage

  • If your device has an SD card, remove it to prevent accidental formatting during the factory reset process. You can do this by going to “Settings” > “Storage” > “Unmount SD card,” and then physically removing the card from your device.

4. Sync Accounts

  • Ensure all your accounts (such as email and contacts) are synced to the cloud. Go to “Settings” > “Accounts” and manually sync each account to make sure everything is up-to-date.

5. Make a List

  • Create a list of apps you use frequently. This will help you remember which apps to reinstall after the reset.

6. Password and Login Information

  • Ensure you have all the necessary passwords and login information for your accounts. Consider using a password manager to keep track of these details.

7. Disable Factory Reset Protection (FRP)

  • If your device has Factory Reset Protection enabled, disable it by removing all Google accounts from your device. This will prevent issues with reactivating your device post-reset.

By following these steps, you can ensure that your important data is backed up and your device is ready for a factory reset. This preparation will help you restore your device smoothly and efficiently after the reset.
