Per a phone call, I entered 1 in the Galaxy keypad as requested. Later on the caller says enter 1. Well the keypad now has 11 and this did not work. How can I remove the first 1 so the second 1 is the correct response?

    What is displayed on the keypad doesn't matter this is just shown to you. Keypad presses are transmitted as DTMF tone, so only when you press a key and the tone is played this is detectable by the other side.
