I've looked on my phone and there is no setting. I'm on T-Mobile. I found a page that has the answer for Verizon but there's no option on mine like the page says.

I couldn´t find it too, and i also want to ask if anyone else having that (aparently) old problem that while we are in a call, if we use the keyboard to change directions (like calling to a callcenter), the keyboard do not work. Can't solve this problem, at all. Even tried to reset smartphone, the first thing i did after reset was trying call again, problem persists.

I have the same issue, it is very disappointing.  I don't know if this is related to network carrier settings or to Samsung phone software setting
