🤔 Why Might You Need a Factory Reset?
Before we dive into the details, let's first understand the situations that require a factory reset:
To protect your privacy and prevent the new buyer from accessing your personal data.
To prepare the old phone for storage or passing it on to a family member.
When temporary files accumulate and cause severe system slowdown that regular solutions can't fix.
In cases of virus or spyware infection that's difficult to remove.
Step One: Back Up Your Photos and Videos 📸
Your photos and videos are irreplaceable memories. Family moments, special occasions, and spontaneous moments you've captured over the years. Losing them means losing a part of your personal history.
Using Google Photos
Google Photos is the most popular choice for cloud backup. But blindly relying on it is a common mistake! Here's what you need to verify:
- Make sure sync is enabled: Open Google Photos app > Tap your profile picture > Backup settings > Ensure the option is "On". For more details, check out our article on comprehensive Android backup.
- Check upload quality: Do you want Original Quality or Storage Saver (compressed)? Original quality consumes your cloud storage space.
- Wait for upload to complete: Check that there are no photos "waiting to upload" before resetting.
Certain folders don't automatically sync with Google Photos! These include: WhatsApp photos folder, photo editing app folders, and photos manually saved in custom folders. You must review them manually and upload them separately.
Additional Backup Alternatives
| Service | Free Storage | Main Feature |
|---|---|---|
| Google Photos | 15 GB | Android integration + AI-powered smart search |
| Samsung Cloud | 5 GB | Full integration with Samsung phones |
| OneDrive | 5 GB | Integration with Windows and Office |
| Personal Computer | Unlimited | Full control + No internet needed |
Step Two: Review Audio Files and Important Documents 🎵📄
While photos get a lot of attention, audio files and documents are often forgotten. These files don't automatically upload to services like Google Photos, making them vulnerable to complete loss.
What Could You Lose?
- Personal voice recordings: Voice messages from family or friends, recordings of important lectures or meetings.
- PDF files and work documents: Contracts, invoices, certificates, or project files.
- Voice memos: Ideas you recorded for yourself or quick notes.
- Music files: Albums you purchased or obtained from sources no longer available.
How to Back Up
- Open the File Manager app on your phone.
- Navigate to folders like:
Downloads,Documents,Recordings,Music. - Select important files and copy them to Google Drive or your computer via USB cable.
- Verify the copy was successful by opening the files from the new location.
Step Three: Transfer Two-Factor Authentication (2FA) Apps 🔐
This step is critically important and many people overlook it! If you use two-factor authentication apps like Google Authenticator, Microsoft Authenticator, or Authy, forgetting to transfer them could mean complete loss of access to your important accounts.
🚨 A Real Catastrophic Scenario:
Imagine you've performed a factory reset, then tried to log into your bank account or email. The site asks for a verification code from your Authenticator app... but the app disappeared with the reset! Now you're locked out of your account, and recovery procedures could take days or weeks.
How to Transfer Google Authenticator
- Open Google Authenticator on your old phone.
- Tap the Menu (⋮) > Transfer accounts > Export accounts.
- Select the accounts you want to transfer and tap Next.
- A QR code will appear. On your new phone, open the app and choose Import accounts, then scan the code.
Golden Tip: Use Authy
Unlike Google Authenticator, Authy supports encrypted cloud synchronization. This means that even if you lose your phone or perform a reset, you can recover all your codes by logging in on the new device. We recommend switching to it for future protection. You can also learn how to enable two-step verification for your Google account for increased security.
Step Four: Disconnect Banking and Financial Apps 🏦
Many banking apps and digital wallets link your account to only one device for security reasons. Performing a factory reset without disconnecting these apps can lead to major problems.
Potential Problems
- Unable to log in from the new device.
- Failed transfers and payments that require app confirmation.
- Having to visit the bank branch in person to re-link the device.
- Disruption of electronic payment services like Apple Pay, Samsung Pay, and Google Wallet.
Safe Steps
- Open each banking app individually.
- Look for "Device Management" or "Disconnect Device" option in settings.
- Officially log out of the app.
- Remove your cards from digital payment services (Google Wallet/Samsung Pay).
- Keep customer service numbers for each bank handy in case any problems occur.
Step Five: Manually Remove Google Account from Phone 📧
This is a step many people completely overlook! Although factory reset deletes the account from the phone itself, it doesn't remove the device from your Google account.
Why Is This Important?
- Accumulation of "ghost devices": Your old devices will continue to appear in your Google Play list and account settings. You can read our guide to finding and deleting your Google data to learn more.
- Security issues: If you're selling the phone, the buyer may be able to recover some data in rare cases.
- FRP Protection: The Factory Reset Protection feature may lock the phone and request the previous Google account when trying to set it up again.
How to Remove Correctly
- Go to Settings on your phone.
- Tap on Accounts or Users & accounts.
- Select the Google account you want to remove.
- Tap Remove account and confirm the action.
- Only now perform the factory reset.
Step Six: Export Local App Data 💾
Some apps, especially open-source or privacy-focused ones, don't sync their data to the cloud. Their data is stored locally only on your phone and will completely disappear with the reset.
Examples of These Apps
- Subscription management apps: Like tracking your monthly subscriptions.
- Local note-taking apps: That don't require creating an account.
- Habit tracking apps: That save your progress locally.
- Games without accounts: Where your game progress will be lost.
- Personal budgeting apps: That keep your expense records.
How to Save Their Data?
Open each app and look in settings for options like:
- Export
- Backup
- Save to file
Save the resulting file to Google Drive or transfer it to your computer, then use the Import option after installing the app on the new device.

❓ Frequently Asked Questions About Factory Reset
Can data be recovered after a factory reset?
In most cases, no. Factory reset is designed to permanently erase data. Some specialized recovery software may recover parts of data if new data hasn't been written over it, but this isn't guaranteed and is expensive. The only reliable solution is backing up beforehand.
How long does a factory reset take?
The process itself takes 5 to 15 minutes depending on the phone and the amount of stored data. After that, the phone will restart and appear as a completely new device ready for setup from scratch.
Does factory reset remove viruses?
Yes, in the vast majority of cases. Factory reset deletes all stored apps and data, including malware. However, in very rare cases, some advanced viruses may infect the system partition and remain even after the reset.
What's the difference between factory reset and erasing everything?
Factory Reset restores the phone to its original state as it came from the factory, deleting all apps, data, and settings. "Erase everything" may sometimes refer to the same process or to deleting data only while keeping apps, depending on the phone's context.
Do I need to remove the SD card before resetting?
It's strongly recommended, especially if important data is stored on the card. Some reset options also include wiping the SD card. To be safe, remove the card before starting or make sure to choose the "Erase internal storage only" option.
