The other week I updated my Sony Xperia z3, wasn't paying too much attention, it asks me to accept updates and I just accept. Now when I type messages my predictive text has almost no words I usually use, previously if this happened I would type the word then put predictive back on and select it, this would store it in the memory. This no longer works, every time I type the words I need to do it manually. I've tried using the learn from messages function, this brings all my words back until I leave messaging then go back in. Any ideas how to fix?
