Thanks for this post. How do things change if you use the default Messenger app vs. Hangouts?<p>I just updated my Messenger app settings to uncheck these options, but when I went into Hangouts to check there, "Auto retrieve MMS" was checked, but all of those boxes were greyed out and it said "SMS disabled - Touch to make Hangouts your default SMS app".<p>So the question then is whether that is a sufficient indicator that Hangouts is not used, and is Hangouts still vulnerable if I am just using the default Messenger app?<p>EDIT:
