Android Question Serial example crashes on incoming data

[Beja]

I could send strings normally, but when I sent a couple of text words it immediately crashed.
No error message.
Galaxy S4, Android 4.1.2

Edit:
Not to mention I have been running this demo without any issue. this is the first time to run it
on GS4

I am having a hard time following your post. What is the difference between strings and text words? I think that text words are contained in strings.

Hi, pls don't stop on that.. they are the same.

edit:
Just noticed the error msg: Connection is broken

This is the NewData sub:

Sub AStream_NewData (Buffer() As Byte)
    LogMessage("You", BytesToString(Buffer, 0, Buffer.Length, "UTF8"))
End Sub

This code is correct. The problem is somewhere else.
