Im having trouble understanding how to use this too. I resprung after installing and bitesms now shows some Chinese characters next to the date, but I still can't make heads nor tails of how to actually use this keyboard. The options in Settings app are vague but I've set everything to US and English, but haven't figured out the next step. I'm going to keep playing with it I'll post a tutorial if I figure it out, but it anyone who has already figured it out would be so kind it'd be amazing to have one handed typing again.
