Sorry if this has been mentioned before but I have predictive text ticked on my chacha which in theory should mean that as I type then the words should appear with the predicted words underneath also with the square 'En' in the bar at the top of the screen, lately though this 'En' has only appeared occasionally or not at all for a few texts then appeared when it wanted to, have I pressed a button I shouldn't have?
My Prediction is still ticked in 'Language & keyboard'......etc.
Thanks for any help.
Reset the phone to factory settings, then update fully.
Seems to fix it, in my case atleast for a few weeks...
Try turning off the shortcuts / hotkeys in the settings as well.
