My phone is sending group messages on it's own. I get a text message with just a link (latest one: tyhyfcyh5r.gghbondxrfv.club), it looks like it comes from an email address, says it is being sent to multiple people (20 recipients). I downloaded Android messages from Google and it says "You created this group MMS with (702) 912-9959 and 19 others." I did not do this and am getting some horrifying replies. What do I do?
