Well, I tried it and even though it works, the keyboard is so hard to read (yes, I changed the different templates and the heights of the keys) and it squishes the numbers on the top row. I uninstalled it.
THIS SUCKS!!! How many millions of people with smart phones that aren't even half as nice as the S4 have auto-correct? ALL OF THEM!!! Why would Samsung leave that BASIC feature out??? I feel like I've taken 10 steps back and now I have to look at every single word I type to make sure it's spelled correctly. Talk about going back in time!! I feel like I'm in high school in typing class!! I'm 55!!!
