how to factory reset android and backup

Factory resetting an Android device can help resolve issues, prepare the device for sale, or clear personal data. However, it’s important to back up your data before doing a factory reset, as this process will erase all data on the device. Here’s how to backup your data and then perform a factory reset: Backing Up Your Data Using Google Backup: Go to Settings: Open your device’s Settings app. Accounts: Tap on Accounts (or Users & accounts). Google: Select your Google account and ensure that options for backing up data (contacts, calendar, app data, etc.) are turned on. Backup: Go back to Settings, then look for System > Backup. Ensure that Back up to Google Drive is turned on. Photos and Videos: Use Google Photos to back up your photos and videos. Open the Google Photos app, tap on your profile icon, go to Photos settings, and select Back up & sync to turn it on. Files and Documents: Use a cloud service such as Google Drive, Dropbox, or OneDrive. Install the app, upload your important files, and ensure they are backed up in the cloud. Third-Party Backup Apps: Consider using third-party apps like Helium or Samsung Smart Switch (for Samsung devices) for more extensive and customizable backups. Manual Backup: Connect the device to a computer via USB, and manually copy files (photos, videos, documents) to the computer. Performing a Factory Reset Once you have backed up your data, you can proceed with the factory reset: Go to Settings: Open your device’s Settings app. System: Scroll down and select System. Reset Options: Tap on Reset or Reset options. Factory Data Reset: Select Factory data reset. Confirmation: Read the information presented, and then tap Reset Phone or Erase Everything. You may need to enter your PIN, password, or another form of authentication. Erase Everything: Confirm again to initiate the factory reset. After Factory Reset Once the reset is complete, your device will reboot and return to the initial setup screen, as if it were brand new. You can sign in with your Google account during setup to restore any backed-up data from Google services. Remember that the steps may vary slightly depending on the Android version and manufacturer of your device, but the overall process is generally similar across most Android devices.
