@BooBear:  I don't know how the S4s works, but try the following:SettingsLanguage and InputSamsung keyboard......then Settings to the side You can either hit Reset, orPersonalized datacheck Clear Personalized dataThe phones start with a list of typical words.  As you use it, it "learns" from what you type and adds those words to the list.  I don't like it to replace any words. I prefer that it "Predict" words that I can select.Also under Samsung Keyboard Settings, there is a Predictive setting.  I have that ON, but if you click on it, another page pops up and you can tell it where to "learn" from.  I turned off everything except Personalized data.Hope this helps! 4951
