How to factory reset an Android phone – A Privacy-Focused Guide
Securely wipe your Android, remove personal data, and restore privacy with this guide.

Your Android phone is more than just a device – it holds your messages, accounts, photos, and personal data. When it starts acting up, gets cluttered with unnecessary apps, or you’re preparing to sell it, a factory reset can help restore it to a clean, optimized state. However, wiping your phone properly is crucial to ensure that no residual data lingers.
This guide will walk you through securely resetting your Android phone while keeping your privacy intact.
When should you factory reset your Android device?
A factory reset can be a game-changer in situations like:
- Suspected malware or spyware – If your phone behaves strangely, a reset eliminates potential hidden threats.
- Slow performance – Years of app installations and cached data can slow things down.
- Selling or gifting your device – You don’t want your personal information falling into someone else’s hands.
- Persistent software issues – If troubleshooting hasn’t worked, a fresh start might be the best solution.
What does a factory reset erase?
A full reset removes:
✅ Installed apps and their data
✅ System settings and preferences
✅ Messages, contacts, and accounts
✅ Photos, downloads, and stored files (unless backed up)
However, it does not remove:
❌ Pre-installed system apps
❌ Android OS updates (your system won’t revert to an older version)
Backing up your data before resetting
Before wiping your device, ensure you’ve backed up what matters:
- Google backup
- Navigate to Settings > Google > Backup.
- Make sure Google Drive backup is turned on.
- Tap Back Up Now to save your most recent data.
- Manually save important files
- Upload critical documents and media to your preferred cloud service.
- Transfer files to an external hard drive or computer.
How to factory reset your Android phone
Method 1: Reset through settings (easiest way)
- Open Settings.
- Scroll to System > Reset options.
- Select Erase all data (factory reset).
- Tap Reset phone, then confirm by selecting Erase everything.
- Your phone will restart and begin the reset process.
Method 2: Using Recovery Mode (if you’re locked out)
If your device is unresponsive or you can’t access settings, Recovery Mode is the next option:
- Turn off your phone.
- Press and hold the Power + Volume Up (or Volume Down, depending on the manufacturer) until the recovery menu appears.
- Use the volume buttons to navigate and select Wipe data/factory reset.
- Confirm by selecting Yes.
- Once finished, select Reboot system now.
Extra steps for a more secure reset
If you’re handing off your phone to someone else, take a few additional steps:
- Remove your Google account before resetting (Settings > Accounts > Google > Remove Account) to avoid activation lock issues.
- Encrypt your data before wiping (Settings > Security > Encrypt phone) to prevent data recovery attempts.
- Verify reset completion: After setup, check Storage in settings to ensure no personal data remains.
Restoring your phone after a reset

- Privacy-focused browsers (Brave)
- Tracker-blocking tools (RethinkDNS, Blokada)
- A secure VPN like NymVPN for private browsing
Final thoughts
A factory reset is one of the most effective ways to refresh your device, fix persistent issues, and remove any potential security threats. Whether you’re just troubleshooting or preparing your phone for a new owner, doing it correctly ensures no sensitive data is left behind.
