Can i turn off the lock screen on a Galaxy Ace 4

When i make a call the screen automatically locks (it shows a large padlock on the screen).

In order to use features during a call you have to double tap the screen to unlock then hold the back key to keep it unlocked.

This is a nightmare when trying to access things like answer phone messages when it says "to listen to your message press 1". you then have to double tap the screen, hold the back key, press 1.... all while you're trying to get a message.

You also have to go through the same process just to end a call.
