Do you know what kind of Spyware she was using to spy on your phone?

Are you sure it's not using one of the family share options?? There's quite a few built-in options between Galaxy and Google?

Go to Settings > Apps on your Galaxy S21 FE.Scroll through the list and look for unfamiliar apps, especially those with names like "System Service," "Device Health," or other generic terms that could be spyware in disguise.Tap any suspicious app and select Uninstall if possible.Check System Apps: Some spyware hides as system apps. Go to Settings > Apps > Show System Apps (tap the three-dot menu to enable this). Look for anything unusual, but be cautious—don’t uninstall critical system apps like "Android System" or "Google Services."Anti-Spyware Scan:Install a reputable antivirus app like Malwarebytes or Bitdefender from the Google Play Store.Run a full scan to detect and remove spyware or malicious apps.3. Check Account Sync and Cloud ServicesGoogle Account:Open Settings > Accounts and Backup > Manage Accounts.Select your Google account and check what’s being synced (e.g., contacts, photos, or app data).If you suspect unauthorized access, go to myaccount.google.com on a secure device, navigate to Security > Your devices, and sign out of any unfamiliar devices.Change your Google account password immediately.Samsung Account:Go to Settings > Accounts and Backup > Manage Accounts > Samsung Account.Check for unusual activity or linked devices.Log in to account.samsung.com, review connected devices, and change your password.Other Cloud Services: Check apps like Dropbox, OneDrive, or Google Photos to ensure they’re not syncing data to another device.4. Inspect Location and Tracking FeaturesGoogle Find My Device:Go to Settings > Security and Privacy > Find My Device.Ensure it’s only linked to your account and disable it temporarily if you suspect misuse.Visit android.com/find on a browser and check which devices have access.Samsung SmartThings Find:Open the SmartThings app and go to the Find tab.Check for linked devices and remove any that don’t belong to you.Location Sharing:Go to Settings > Location > Location Services > Google Location Sharing.Disable any sharing with your wife’s account or others.5. Check for Remote Access or Screen SharingScreen Mirroring/Casting:Go to Settings > Connections > Screen Mirroring or Smart View.Ensure it’s disabled and no devices are connected.Remote Access Apps: Check for apps like TeamViewer, AnyDesk, or AirDroid. Uninstall them if found, unless you intentionally use them.Accessibility Services: Spyware sometimes uses Accessibility Services to monitor your screen.Go to Settings > Accessibility > Installed Services.Disable any unfamiliar services or apps listed there.6. Secure Your PhoneChange Passwords:Update passwords for your Google account, Samsung account, and any other accounts linked to your phone.Use strong, unique passwords and enable two-factor authentication (2FA) wherever possible.Update Software:Go to Settings > Software Update and ensure your phone is running the latest Android version and security patches.Spyware often exploits outdated software.Revoke App Permissions:Go to Settings > Apps, select each app, and review permissions (e.g., camera, microphone, location).Revoke unnecessary permissions.Disable Unknown Sources:Go to Settings > Security and Privacy > Install Unknown Apps.Ensure no apps are allowed to install from unknown sources.7. Perform a Factory Reset (Last Resort)If you can’t find the tracker or suspect persistent monitoring:Backup Important Data:Save contacts, photos, and essential files to a secure, non-synced location (e.g., an external drive). Avoid backing up to Google or Samsung Cloud until you’re sure your accounts are secure. Factory Reset:Go to Settings > General Management > Reset > Factory Data Reset. Follow the prompts to erase all data and restore the phone to its original state. Set Up as New: After resetting, set up the phone without restoring from a backup, as the backup might include the spyware. Manually reinstall apps from the Google Play Store. 8. Investigate How It was installed. Physical Access: Spyware usually requires physical access to your phone
