I have English, Chinese, Japanese and German enabled. I find the keyboard in general rather laggy for me, but nothing unbearable. The exception is Japanese, which I am virtually unable to use, both because of extreme lag and because the keyboard can't seem to handle simple phrases or words and will stop showing suggestions.
Is anyone else experiencing this? Is it an issue with the Japanese keyboard itself, or is it because SwiftKey is becoming overwhelmed by having to make predictions in four languages simultaneously? If it is the latter, would it be possible to switch off this function and switch languages manually? I understand that this is a vital function for many people, but I personally don't need to type in all four languages at once.
Thanks very much! :)
