Some incoming message go to HTC MESSAGES not Google Hangouts.

My M8 is causing me issues with messages I recieve from one person. For everyone else, messages go to Hangouts, but a friend with an S5 causes me this problem: If he sends me an SMS it goes to Hangouts. I then reply and if he replies to that it switches on his phone to CHAT in his S5 Messaging system and then is received by Messages on my M8, not Hangouts.

I have selected Hanouts as default SMS system. What's going on here?

Well, that's cleared up that little mystery....

I'm going to take a wild guess... Perhaps it's something in the chat from the S5 (I think it supports vid conferencing) that might be supported by the stock message app of the M8 and not hangouts. I think we are all stumped or someone would have responded to your question.
