Lock screen when making a call

[jhonnybig82]

I have a Samsung S5282 and when I make a call appear on the screen a lock and it blocks, not letting me have access to disconnect the call function for example.
I've seen the phone settings and found nothing that disables this function, someone can tell me if it is possible to remove this feature and how can I do that.
Android 4.2

thanks

In security option set the time limit for lock screen.
