How can I turn off "double tap to unlock" on Galaxy Ace Style?

[AC Question]

It is impossible to use the dial pad to enter options while phoning a company as the "double tap" kicks in and disables everything. All suggestions on forums do not help. It is suggested that it cannot be turned off. Correct?

Are you not able to just hit the power button while on a call and unlock the phone normally?
