I need long touch tones when dialing- some tone recognition systems I call don't recognize the very short tones on my Galaxy S2. There does not appear to be an option to change to ton continuous tones. I called Samsung and wasted my bucket of minutes on a rep that took way too long to give me an "answer" that had taken me a minute to discover- the option is not there! So how do I change to continuous tones when pressing keypad??
