Hello Boldbeast
I just wanted to let you know that I just got a Pixel 5 (Unlocked version US) that has Android 11 out of the box. I do not have the phone rooted yet so I was unable to test it that way. I can confirm that with nothing done Boldbeast does not work. After I gave it accessibility permissions I was able to record calls but I can not hear the other side on the recording. Of course, the recording does work if I am able to record with the speakerphone on. I have not decided to root this phone yet so if I do I will let you know the outcome. There are root guides for it on XDA.
