This is outright annoying. Not only does the phone switch into driving mode without warning, it never switches out. I turn it off and turn it off and turn it off. I don't ever want it coming on. I have auto-answer earpiece and blue tooth this & that, I don't EVER want this phone changing its settings "because it thinks it knows better".
How does one permanently disable this?
Do I need to switch carriers again?
Go to settings, sound settings, driving mode. turn it off. This is turning on because your pressing and holding your speaker phone button which will auto enable driving mode.
