How to format your Android phone without losing data

Is your Android slow, cluttered, or acting up? You can format it and keep your photos, contacts, and apps. Below is the step-by-step method I use.

In one of my previous articles I promised to write an article on how you can format your Android phone without losing data, now you have it. So let's dive in..

Why format your phone

  • Speed up your device by removing junk files
  • Fix software glitches
  • Wipe the phone before selling or giving it away
  • Remove malware and persistent bugs
  • Start fresh with better performance

Step 1: Back up your data

Do these before you format. You keep control of your files.

  • Google backup — enable Backup to save app data, device settings, call history, and SMS
  • Photos and videos — use Google Photos, enable Backup and sync, or copy to a laptop or USB
  • Contacts — sync with Google or export as a VCF file
  • Messages and call logs — use SMS Backup & Restore to export backups
  • Apps and app data — confirm Google Backup is on; open key apps and export data if available
  • Files and documents — copy to cloud storage or your computer
  • WhatsApp — back up chats to Google Drive via WhatsApp settings

Step 2: Remove Google account lock

Prevent lockout after reset.

  • Go to Settings > Accounts > Google
  • Remove the Google account from the device
  • Note your Google credentials. You will need them to sign in later

Step 3: Format the phone

Choose a method based on your phone state.

  • Factory reset via Settings — Settings > System > Reset > Factory data reset
  • Hard reset via Recovery Mode — use if the phone will not boot. Power off, press the device keys for your model, choose wipe data/factory reset

Step 4: Set up your phone

  • Select language and region
  • Connect to Wi-Fi
  • Sign in with your Google account
  • When prompted, choose to restore from your Google backup

Step 5: Restore your data

  • Photos and videos — open Google Photos and sign in
  • Messages — open SMS Backup & Restore and restore from the backup file
  • WhatsApp — install WhatsApp, verify your number, restore chats from Google Drive
  • Files — re-download from cloud storage or copy back from your computer

Post-format tips

  • Install apps gradually, avoid restoring everything at once
  • Enable automatic backups in Settings
  • Update Android and apps after restore
  • Review app permissions and remove unused apps
  • Set a screen lock and enable Find My Device

Common issues and fixes

  • Google account verification required — sign in with the Google account used before the reset. Recover the password at accounts.google.com if needed
  • Apps not restoring — check internet and Google account, install apps from Play Store manually if needed
  • Photos not appearing — confirm Google Photos backup completed before the reset, wait for sync on slow connections
  • Missing contacts — go to Settings > Accounts > Google, toggle Contacts sync off and on, allow a few minutes to sync

Troubleshooting quick fixes

  • If the phone still lags, clear cache partition from Recovery Mode
  • If apps crash, reinstall the problem apps
  • If battery drains, check battery usage in Settings and uninstall battery-heavy apps

Quick recap

  • Back up to Google and cloud storage
  • Export important files and contacts
  • Remove Google account from the device
  • Factory reset or hard reset
  • Sign in and restore data
