Important: When you press to activate your Google Assistant, it no longer reads notifications on headphones. You can still say, "Hey Google, read my notifications".
Ask to hear unread notifications
On your phone, you can also check what unread notifications you have.
On your headphones, activate Google Assistant and say "Read my notifications".
How notifications and Google Assistant language settings work
On your phone, if you have different languages set up, Google Assistant reads your notifications in the language that the message was received in.
Tip: To have a better Google Assistant experience, make sure that you have the same language set for your Google Assistant and your phone's system display.
