Google Phone app will have a flip to mute function soon in Android devices. XDA-Developers have found in the beta version of Google Phone 47 new useful features that will soon appear in the application.
The program code mentions the Flip to Mute function, which will allow users to quickly turn off the sound of a call. To do this, you will need to turn the smartphone screen down on a flat surface. By the way, Pixel devices now have a similar feature (Flip to Shhh), but it puts the device in Do Not Disturb mode.
There is a also a one-way video function in Google Phone 47 beta. There is no details on this, but we can only assume that we are talking about answering calls using short clips.
