Long story short I ended up getting spyware from an MSM message sent to me on my old S6 and few days later it started acting weird (pics and vids taken that weren't me, echoes and clicks in my calls, etc) with all the signs of somebody having remote access of my phone. I backed everything up to Google Drive and went and got the new S7. However, the person who sent me the initial MMS tried to send me another one (which I did now download). However, most Androids have auto-retrieval of MMS so I guess it didn't matter that I didn't download it because it probably self extracted onto my phone. All of the symptoms started again. So the next day I went in and replaced the S7. I have changed all the passwords to each of my other accounts and have not gotten any MMS messages. However, after syncing with my Gmail account the problems started happening again. I've done a factory reset and I'm sitting here out completely confused and was told the genius level Android experts on this thread may be able to help me. Is it possible that my google account is now compromised and I would have to ditch my google account (including gmail and drive which contains years of invaluable files)? I have changed my SIM cards each time but my phone number has stayed the same.
Also, this month's bill is saying I've sent over 1500 txt messages...which is way more than what I would normally send out (I average roughly 400-600 depending on how busy the month is). I'm not very tech savvy...can anybody out there please help me figure out a way to fix this problem so I can finally use my S7 without feeling like somebody is watching me or listening to me from another remote location?? Thank you!! :(
