I do not see an answer for the question. How to find out or tell if my phone has been hacked or has a spyware installed on it. All I see is that spyware only exist on android devices & telling people to install mobile security & antivirus by avast. Well, if the phone already has spyware on it, will the security & antivirus app work correctly? Or will it be bogus? Please please help us out here!
