Thanks for the reply! This isn't very clear to me. I actually opened the link in a new tab with Firefox for Android, had Firefox ask me for permission to access my camera and mike(?), denied those and closed the tab as I read pascalmemories' comment i.e. I never actually saw the content, so "you would have to download the app they spammed with vibrates" doesn't mean anything to me. Perhaps that's a good thing? :)

I've turned off the phone for now, and it's not 6.0, rather it's 6.x (up to date with August 2016 patches IIRC), not sure if that makes a difference. I'm mostly worried about the malware being a drive-by download/infection.
