Google Duo APK Reviews

If you don’t need a ladder all the way, it will replace Facetime. In addition, before you answer the call, you can see the other party's anxious, expectant or funny appearance (don't worry, the other party can't see you). Think about it, if you see the angry faces of your boss and colleagues in the conference room in the incoming call information, you can also be mentally prepared to connect to the video message, or pretend not to see it tactfully and gracefully.
