How do I Enable the keyboard to auto correct using the Blue Suggested word?

[shanezam203]

That may sound like a simple request, but for the life of me on an old Galaxy s4 and now my s4 mini I do not see the option or have the experiance where auto correct is fixing my misspelled words. In attachment I typed "Sorry phone qas" and was hoping it would auto correct qas to was (which is an option but I have to select it in blue) How do I make it auto auto correct to the letter in blue?

Thank you,

Shane
