I have just got a HTC One and so far i really like it, but it's really bugging me that i can't seem to turn predictive text off. I've always hated it and i really don't want it turned on as it takes me twice as long to type anything! But, after a bit of digging around, i found my way into Settings -> Language and Keyboard -> HTC Sense Input -> Advanced, and in there, there is a section entitled "Prediction Preference" with 2 options: the top one is, "Word Prediction: Suggestion options for current word while typing," which is checked by default and greyed out so you can't uncheck it, and below that, "Next Word Prediction: Suggestion options for the next word while typing," which is currently unchecked. Please tell me this doesn't mean there's no way of turning predictive text off, permanently?!
