The microphone button has vanished from the keyboard buttons. I've seen the solution of putting it on the navigation bar. I want to know how to put it back on the keyboard buttons. I use my phone one-handed very often, and it's easier to have it placed at the top of the keyboard to the right where I can push the button. I haven't seen anyone able to tell me how to put it back up there instead of on the navigation bar, which is supposed to be for navigating my phone, not for keyboard input. Can anyone help me?
