iPhone 11 Pro Max Typing Phrases Spontaneously
Frequently when my wife is typing in a message, her iPhone 11 Pro Max takes over and begins typing somewhat random words and phrases, on and on, not stopping until the iPhone is powered off and restarted. My identical phone never does this. Many of the phrases appearing on the screen are composed of related words and seem to have some meaning for brief moments, like snippets of prior texts except that they include words and phrases she is sure she did not ever say. Words are often repeated two or three times. They appear at a steady pace, about the speed a moderately skilled person would type but steadily, with none of the bursts and hesitations I would expect if a person were typing.
I hope someone recognizes this pattern and can tell us what to do about it.
