Google Duo v45 prepares pre-call notifications, continues work on Low Light mode and sending pre-recorded videos [APK Teardown]. You know Skype, and you know Facetime, and you know other video calling apps; but, do you know Duo? I have been playing with Duo for a while; and, like everything Google, it keeps getting better. I have it installed on my phone, and it is very nice to reach out and see someone whenever you want. Call me, maybe?
