Android introduced a predictive text bar that is very useful. A predictive text keyboard powered by a bilingual dictionary, it works when you're texting, emailing or using your favourite apps, putting split-second word lookups at your fingertips. I love that features.
Go to " Messages" - create a new message and swipe down you will see - Choose Input Method- samsung keyboard. Click on it.
Or you can go to "CONTROLS" and choose "Language and Input" you will see the Samsung Keyboard.
Click on " Samsung Keyboard"
Click on the "Icon" on the right
Take note of the Predictive Text- Click "ON" green light
Predictive text is just one of those things you either love it or hate it. Is a matter of facts that you get use to it.
Predictive text available for Android Version 4.4.2
