This N900 drives me crazy! I am an English learner, Word completion and Auto-capitalization are very important and convenient to me. I have checked Word completion and Auto-capitalization in the Text input setting, but still doesn't do any help. To make sure, I tried a couple of times, check them out, restart, then check them again, restart, It just doesn't work at all. Any help please!!!!!!!!!!!!!!!! Do I have to restore it to factory setting.
