Fix Google Duo Not Showing Contacts on Android & iPhone

Let’s start by looking for updates available for the app.

Update Google Duo

As I said, maybe there is some bug that is not allowing you to see the desired contacts you want to connect via Duo. So, check if there is an update available to install. Normally, if there are any bugs, then Google releases updates to fix it up.

  • Launch Play Store app
  • tap on Hamburger app > select My Apps & Games
  • In the loss of apps waiting to receive an update, check if Google Duo is present there.
  • If yes, then beside the app you should see an Update option. Tap on it.
  • Re-launch the app after finishing the update

Now, check if you can see your contact details while trying to establish a connection. You can try the same on App Store if you use a device running on iOS.

Check if Permission is Granted to Google Duo to Access Contacts

On Android,

  • Long press on Google Duo > tap on info button (with an i symbol)
    Google Duo App Info
  • From the screen that opens up, tap on Permissions
  • You should see two sections Allow and Denied.
    Check App permissions for Google Duo to Access Contacts
  • As you can see, in my Android phone Google Duo is allowed to access contacts. So, the Allow option is selected.

On iPhone

  • Launch Settings App
  • Go to Privacy > select Contacts
  • Now, you should see the apps that have access to the Contacts present on your iPhone.
  • It must have Google Duo on it. Make sure the toggle beside it is enabled.


When you install Google Duo and access it for the very first time, the app will by default ask you permission for accessing Contacts and other required things for it to work as it is designed. Only if you Allow it the necessary permissions, the same will show up in the Settings. This applies to both Android OS and iOS.

Are the Contacts That You Trying to Video Call Saved on Your Device

Have you saved the contact details like the phone number of the person you are trying to connect correctly on your device.? Otherwise, Google Duo will mark the number/potential contact as alien. So, check-in your Contacts list if you have saved the correct number. Otherwise, for video calling the concerned person is using a different number.

Clear the App Cache

Sometimes junk files such as the temporary files keep accumulating in the memory-making the memory unavailable for various tasks of an app. So, you end up facing issues such as app crash, slow down, a particular feature not working, etc. So, the fix is to clear the cache of the app which in this case is Google Duo. This method is only applicable to Android OS.

  • Go to Setting > Apps & Notitifcations
  • Under See All Apps > Scroll down to Google Duo. Tap on it to open it.
    cache clear of Google Duo is Contacts not Showing on Duo
  • Then tap on Storage & Cache > tap Clear Cache
  • Reopen the app

Now, try to connect to your contact through video calling. It should work finely.

So, that’s it. If Google Duo is not showing Contacts on your device, then make sure to follow these troubleshooting methods and try to fix it up. Let me know in the comments section if you have got any queries relating to this guide.
