What Is a Factory Reset?

A factory reset (also called a hard reset or master reset) wipes your Android device back to its original out-of-the-box state. It deletes all personal data, installed apps, accounts, and settings. Think of it as a fresh start for your device.

When Should You Factory Reset?

  • Your phone is running very slowly and cleaning hasn't helped
  • You're selling or giving away your device
  • Your phone is stuck in a boot loop
  • You suspect malware or a virus infection
  • An app is causing persistent crashes or errors
  • You're upgrading and want to wipe your old device

Before You Reset: Important Preparations

Warning: A factory reset is irreversible. Everything stored locally on your device will be deleted. Complete these steps first:

  1. Back up your photos and videos – Use Google Photos, a USB cable transfer, or cloud backup.
  2. Back up contacts – Sync to your Google account via Settings → Google → Sync.
  3. Note your app list – Once reset, you'll need to reinstall apps manually. Screenshot your home screen for reference.
  4. Back up app data – Some games and apps don't backup automatically. Check individually.
  5. Remove your Google account (optional) – On newer Android devices, Factory Reset Protection (FRP) requires the original Google account login after a reset. Removing it first can prevent lockout issues.
  6. Charge your battery – Ensure at least 70% battery before starting.

Method 1: Factory Reset via Settings (Most Common)

This is the standard method for a normally functioning phone:

  1. Open Settings
  2. Scroll to General Management (Samsung) or System (Stock Android)
  3. Tap Reset
  4. Select Factory Data Reset
  5. Review what will be deleted, then tap Reset
  6. Enter your PIN or password if prompted
  7. Tap Delete All to confirm
  8. Wait for the process to complete (5–15 minutes)

Method 2: Factory Reset via Recovery Mode

Use this if your phone won't boot normally or the Settings method isn't accessible:

  1. Power off your phone completely
  2. Enter Recovery Mode – The button combination varies by brand:
    • Samsung: Hold Volume Up + Power + Bixby button simultaneously
    • Stock Android / Pixel: Hold Power + Volume Down, then select Recovery
    • Other brands: Usually Volume Down + Power, or check your manufacturer's guide
  3. Use Volume buttons to navigate the recovery menu
  4. Select Wipe data / Factory Reset
  5. Confirm the action
  6. Select Reboot System Now when done

After the Reset: What to Expect

Your phone will restart and walk you through the initial setup process just like when it was new. You'll need to:

  • Select your language and region
  • Connect to Wi-Fi
  • Sign in with your Google account
  • Restore apps and settings if you had a backup
  • Set up security (PIN, fingerprint, face unlock)

Troubleshooting: Factory Reset Protection (FRP)

If you see a Google account verification screen after resetting and can't get past it, you've triggered FRP. You must sign in with the Google account that was previously linked to the device. If you've forgotten those credentials, account recovery through Google is required — this is a security feature by design.

Conclusion

A factory reset is one of the most powerful troubleshooting tools available on Android. Done correctly with a proper backup beforehand, it can breathe new life into a sluggish phone or safely prepare your device for a new owner.
