Samsung Phone Users Perturbed to Find They Can't Delete Facebook
I also noticed when troubleshooting a VPN and doing some tcpdumps that my Xperia Z5C was making pretty frequent DNS lookups of mqtt-mini.facebook.com . From what I could find on Google search my best guess was that this endpoint is used by facebook messenger, but I don't have that installed. This is despite the fact that I've disabled the facebook app.I took a second look while writing this comment and there's an addtional "Facebook services" app, which I've just gone ahead and disabled. Maybe that will stop the requests.
