Samsung Chinese IME keyboard can type but cannot sent chat messages

Hello,

First off, I want to say that MinecraftPE 0.13.0 isamazing!
My two sons and I love it!!!

Next, I would like to report an issue we are having.
My two sons play MCPE on their sumsung phone.
After updating MCPE 0.13.0 bulid 1,they found that can not type, whether in the taiking sreen or in signs.
My kids even can not communicate with another fridends when they are playing online.
They feel terrible.
The build 5（you said it is the last build one） has came out， the problem still do not fix，my kids are still waiting.
However, because off that, (trying to be a good parent and do not want see the loss expression on their face） I had to uninstall your program.
Please see if you can fix this in one of your coming updates.
My kids are begging you.
