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 !
You can never know. If there’s ever a doubt, do a factory reset and start from scratch. Keep the phone secure keep the password safe. Use biometrics to reduce your risk surface of people shoulders surfing your code.
The same goes for any computer once it’s been compromised you can’t trust it at all. If you want to be safe you start from scratch
