when i right messages using predictive texts, some of the words are not in the dictionary, so i have to spell them out, my phone used to remember these, but now it doesn't for some reason? does anyone know why?
If you haven't upgraded your firmware, then it could be that you've filled you T9 dictionary. I've found over time that words that I've added earlier tend to disappear later if I've continued to add words. Maybe, dispite the amount of memory on the phone, it can only hold X number of custom words.
