It is really important what types of streamed objects you use to operate with data. It seems to me that this troubleshooting is created by the fact that you use DataOutputStream for sending info, but something else for receiving. Try to send and receive info by DataOutputStream and DataInputStream respectively.

Matter fact, if you send something by calling dataOut.writeBoolean(b) but trying to receive this thing by calling dataIn.readString(), you will eventually get nothing. DataInputStream and DataOutputStream are type-sensitive. Try to refactor your code keeping it in mind.

Moreover, some input streams return on invocation of read() a single byte. Here you try to convert this one single byte into char, while in java char by default consists of two bytes.

       msgChar = (char)dataIn.read();

Check whether it is a reason of data loss.
