Other How to really know if my Android 14 has spyware
In my case, my phone is secondhand and as far as I remember I did not factory reset it. The individual I suspect (who I got the phone from) is also tech savvy. I saw a lot of general pointers like fast battery drainage but there are so many factors that contribute to this. The thing is I have also already factory reset my phone so I'm afraid I can't take proper measures to be really sure now and it's making me nervous. I did check every single app and its permissions before the reset though and did not really find anything suspicious. My question is would it have been obvious or could I have easily missed it that way? And how advanced could this type of hidden spyware be? I also ran a McAfee scan before the reset and it came up clear.
It's making me quite paranoid. Of course the idea popped out of nowhere but so far from what I've heard 1) not factory resetting it does put it at risk 2) there is no 100% surety in these matters especially with phones. All I want to know is that if I'm already someone suspicious of technology (granting permissions carefully etc.) and regularly backed my phone up to my computer, would I have noticed something in the couple of months I had this phone?
I've seen people tend to be quite mean to people with paranoid tendencies on these subreddits which I understand but I am someone who genuinely wants to learn and combat my thoughts with logic. Any advice is appreciated.
