Hello ! I hope I’m at the good place. A friend of mine asked me :
How do I know if someone has physically accessed my phone? Knowing that this person knows my unlock code. Also, how do I know I’m not being spied on remotely?
I didn’t have the answer and thought I might as well ask there. Thank you.
EDIT : His phone is a Samsung Z Fold 3 is that can help !
I don’t know, I don’t have all the details. But people you trust today might not be worthy of trust tomorrow, I guess.
At this point I’d back up your photos, etc, and factory reset the phone. Then use a different passcode. Don’t forget to back up MFA credentials so you can get into your Google account after the reset.
