I want to type 'A' not 'S'

Its a predictive text entry, either the first time you pressed that button you picked "s" or when using the button you choose "s" more often. Only way to change this is press the "as" button and pick "a" you will have to this this a few times for it to work. I had the same issue with hey and get... Or you could delete your saved word and start over picking "a" the first time you use the "as" button
