Galaxy S5 blank messages

I want to disable being able to send blank messages, my partner can't and she has a galaxy s5 as well but she doesn't know how it got disabled.

any help would be appreciated

Both of us are using the default Samsung messaging program

Re: Galaxy S5 blank messages

It probably depends on the messaging app she's using. Have her check Settings in the menu for something about that. Then use the same app and do the same thing. (None of my messaging apps have any setting for that.)
