This issue is driving me mad! I've asked on a couple of other forums and, as yet, nobody knows of a solution. I use predictive texting. Very often, more often than not in fact, when I begin a new sentence in an SMS (or posting on facebook), the first two letters of the word are capitalised and no matter how many times I backspace and try again, it won't use a lower-case letter. I've tried going through my dictionary and deleting each and every one of the 'wrong' words it saves...to no avail. I took a screenshot earlier of a post I made on facebook using my 'phone.... A friend of mine who has a Samsung Galaxy says her 'phone has the same issue so maybe it's a general Android issue?? Please, does anyone have a solution to this issue?!
