How do I know if someone has physically accessed my phone?
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 !
There are apparently some apps for this specific case, like WTMP "Who Touched My Phone". I haven't used it, though.
If they have your passcode then no? Why would you give your passcode to someone you don’t trust?
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.
It would depend on the type of phone. Is it an iPhone or Android?
It's an Android.
EDIT : A Samsung Z Fold 3 to be more precise.
Check for apps that are running in the background after you have closed everything.
From what I understood, it didn't just happened. A certain person knows things about him that he never told, or something like that.
Thanks for the suggestion, though. That's a nice idea.
It could be semi-public details. A google search and someone’s social media can give you a lot of information on a person, depending on how safe their internet practices are. Generally all you need are two or three details to find out more personal information if you wanted to.
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
