When I first got my Samsung Galaxy S5, this had never occurred. Then, I recall enabling WiFi Calling and ever since, every incoming MMS text comes with a prefix line that reads <Subject: No Subject>. I tried resetting my phone to factory settings and switching between all APNs and nothing worked. I don't think that WiFi Calling is actually the cause of the issue but the coincidence is suspicious to me. How do I fix this so that I don't ever need to see that annoying Subject line at the beginning of every text in a group message?!
Edit: forgot to mention that I'm using Google's Hangout app but I noticed the same thing with the S5's stock text messaging app.
