The answer is the same as in the thread you posted a link to. It's a  
broken client request; the FOLDERID tag MUST contain a valid folder  
identifier. In this case, the client is sending an empty tag.

If you are able to obtain a full wiretrace of the connection using a  
tool like wireshark, I can look to see *exactly* what WBXML is being  
sent to be sure I'm understanding the issue. Otherwise there is  
nothing else I can do.

FWIW, I have both a stock Note 3 and a stock Galaxy S5 - neither of  
which exhibit this behavior.
