The average smartphone user receives approximately 4.6 spam calls per day, according to RoboKiller's 2024 Phone Spam Report. After spending weeks fine-tuning your Call Triage settings to block those nuisance calls, losing that configuration during a phone upgrade can feel frustrating. Here's how to protect your custom spam-blocking setup so you can preserve it during a device transition.
Export Your Custom Blocking Rules First
Your custom blocking rules are a key part of your Call Triage setup. They include specific number patterns, area codes you've blocked, and keyword filters you've created. Losing these can significantly impact your personalized spam protection.
Open Call Triage and navigate to Settings > Backup & Export. Tap "Export Blocking Rules" to generate a JSON file containing your custom filters. By default, the app typically saves this file to your device's Downloads folder, though you can usually choose a different location.
Testing on both a Pixel 8 and Galaxy S24 showed the export completing in under 10 seconds on both devices, creating files around 2-5KB depending on how many custom rules you've created.
Save Your Whitelist and Important Contacts
Your whitelist contains the phone numbers and contacts you've specifically allowed through Call Triage's filters—family members, doctors, delivery services, and other legitimate callers you don't want blocked.
In the same Backup & Export menu, tap "Export Whitelist." This creates a separate file containing your approved numbers and contact exceptions, including both manually added numbers and contacts automatically whitelisted from your address book.
Here's what matters: Call Triage typically doesn't automatically sync your whitelist with your Google contacts. If you've manually added numbers that aren't in your phone's contact list, this export is an important way to preserve them.
Back Up Your App Preferences and Settings
Beyond blocking rules, Call Triage stores numerous configuration options: notification preferences, ringtone settings, auto-response messages, and screening sensitivity levels. These preferences shape how the app behaves every single day.
The "Export All Settings" option creates a comprehensive backup file containing your complete Call Triage configuration—blocking rules, whitelist, notification settings, and interface preferences all in one place.
Using this comprehensive export as your primary backup method is recommended. The individual exports (rules-only, whitelist-only) are useful for sharing specific configurations or troubleshooting, but the complete settings backup helps ensure nothing gets lost in the process.
Store Backups in Multiple Secure Locations
Your backup files are only useful if you can access them when you need them. Storing them solely on your device reduces their value if that device is lost, stolen, or damaged.
Consider uploading your Call Triage backup files to at least two cloud storage services. Google Drive and Dropbox are common choices for primary and secondary storage. The files are small—typically under 10KB—so storage space isn't a concern.
"The best backup is the one you can actually access when your phone dies at 2 AM and you need to restore everything on a replacement device."
For added security, consider encrypting your backup files before uploading them to cloud storage. These files contain your phone numbers and contact information, which could be sensitive if accessed by unauthorized parties.
Test Your Backup Files Before You Need Them
A backup you haven't tested is just a file taking up storage space. Testing backup files periodically helps catch potential issues before you actually need to restore them.
Every few months, download your backup files and verify they open correctly. You don't need to actually restore them, just confirm the files aren't corrupted and contain the expected data. Open the JSON files in any text editor to spot-check that your custom rules and whitelist entries are present.
Restore Settings on Your New Device
When setting up Call Triage on a new device, install the app first but skip the initial setup wizard. Instead, go directly to Settings > Backup & Export and tap "Import Settings."
Select your comprehensive backup file (the "All Settings" export). Call Triage will typically prompt you to confirm the import, showing a preview of how many blocking rules, whitelist entries, and preferences will be restored. Tap "Import" to apply your saved configuration.
Here's an important consideration: the import process generally overwrites Call Triage's default settings. If you've already started customizing the app on your new device, those changes may be lost. It's typically best to import your backup before making any manual adjustments.
Two More Tricks Worth Knowing
Share configurations across multiple devices: If you use Call Triage on both a phone and tablet, you can share the same blocking rules by importing the same backup file on both devices. This can help ensure consistent spam protection across your devices.
Create configuration templates: Export your settings after achieving good spam blocking performance, then use that file as a template for family members or colleagues. They can benefit from your optimized configuration without starting from scratch.
Quick Action Summary
Here's your backup and restore checklist:
- Export your complete Call Triage settings monthly
- Store backup files in multiple cloud storage locations
- Test backup file integrity every few months
- Import settings before customizing Call Triage on new devices
- Keep backup files encrypted if they contain sensitive information
- Use descriptive filenames with dates for easy identification
- Consider sharing optimized configurations with family members
