I updated to JellyBean a couple of weeks ago, and since then I have a problem with the T9 function: It won't let me write certain things, such as the word for "me" (I'm Swedish) or the letter "t". Incredibly annoying! When I add the word to my dictionary it works when texting in English, but not in Swedish. Which is pointless. Instead it suggests meaningless gibberish, and I have to toggle back and forth between T9 and ABC.
The other problem since updating is when trying to use Facebook through the browser: I click the commentary field to write a comment, the keyboard pops up, and - covers the field so it's impossible to see what I'm writing. Before, I could scroll up so both were visible.

Is there anything I can do? A keyboard app that might work better? Can I go back to the previous OS?

Grrrrr.
