Try more fixes

If you need more tips, try these:

Turn on Duo notifications

Check that notifications aren't blocked in both these places:

  • Your device settings: Open your device's Settings Settings  and then Notifications  and then Duo and then Check that "Block all" is off. 
  • In the app: Open Duo and then More More and then Notifications and then Turn on Call notifications.
Check blocked numbers
Check that the phone number isn't blocked.
  1. Open Duo and then More More and then Settings and then Blocked numbers.
  2. Check that the phone number isn't listed.
Avoid using "Force stop"

If you've used "Force stop" through the Android settings app, then you'll need to re-open the app for the notifications to work.

Allow Duo to work in the background

Check that background data is on for Duo and Google Play services.

  1. Open your device's Settings Settings
  2. Tap Apps and then Duo and then Data usage. 
  3. Turn on Background data.
  4. Repeat the above steps for Google Play services.
Turn off "Battery Saver" mode

Battery saver can block Duo from sending notifications. Learn how to turn off battery saver.

Apps not made by Google, like Juice Defender or Antivirus, may not allow notifications to work. Other manufacturers may have their own battery saver modes to check:

  • Sony: Try disabling “Stamina” mode.
  • Huawei: Mark Duo as a protected app through Energy Saver  and then Protected Apps.
  • Xiaomi/MIUI: Check that the power saving modes are off. Also, open the security app and then Permissions and then Add Duo to Autostart. Start the Task Manager, find Duo, and drag it downwards until the padlock icon appears.
