Android 12 come with an annoying floating button, that is always on the wrong place and that you need to move around all the time. I have tried it on the left side, on the right side, up on the screen, basically anywhere. and it always disturbs. Ok there is a new feature. I got it. Let’s get rid of that button.
It is actually quite easy. Go to your phone settings, search for sound amplifier
click on the menu item and you should see the following:
Deactivate the Sound Amplifier shortcut
, and that is it!
