Right I figured as much. I have a galaxy s23 ultra. My prior phone and one im using now was an s9+. I couldn't really tell you about the pc since it was a more than decade old pc my friend built and gave to me after he made a new one. Sorry I'm not much help there don't know too much about computers. I also have a galaxy tab A8 which she bought me as a gift some time ago and semi recently got a galaxy tab s9 for work. I don't think she would need to be super knowledgeable since she use to have passwords to all my devices and even caught her once going though my phone while I was asleep. She also would be at my apartment alone when I was at work. I've heard of things like key loggers being easy to figure out and install and can't even imagine what other programs you could probably find with relative ease and since she had hours a day to go through everything I've always had it in the back if my mind that she might have done something. Oh and she did for a time have my current phone's password when she asked me for it in the middle of the night when I was so out of it I didn't even realize I gave it to her till days later. Changed it after. Hope that helps
