Just delete your messages before you give it back.
no if you used they phone .. it was your job to remove ur message... since when you give back the phone to that person he got control over everything in it even your conversation since its he phone
yup delete it or use ya on phone.
If you're in a position that requires you to surveil the outgoing and incoming messages from your personal communication devices, don't let other people use it! Simple as that. I'm in that sort of position, but I still like to respect privacy.
I wouldn't write stuff on other people's phones that's not okay for them to see.
I don't have friends like that in life. I choose my friends wisely. So I wouldn't put up with that.
Only if they want to lose all their digits......
it violates their privacy
