Why does my boyfriend hide and lock his phone?

He's not hiding the phone (unless of course he fears that it would be stolen), he's hiding something or someone on it.

i think he could be cheating, or just talkin to the other girls. ide be suspicious. if someones got nothin to hide, they hide nothing.

well ask him tell he says an answer same thing happend to me he was cheatin

soooo dont get your hopes up

Cheating is not the only reason a boyfriend would hide/lock his phone,one reason could be is that you are just a girlfriend and are not entitled to an all exclusive stroll through someone elses privacy unless they allow you to...just as you probably would not take to kindly to a boyfriend looking through your purse,your phone,your jewelry box,your dressor drawers, through a box in your closet or through your emails and snail mail...there are areas of privacy that everyone is entitled to have..even among married couples.This is a basic concept that most women have trouble with, they seem to think that they are entitled to know,see,hear,watch and be involved in every single thing on different levels according to their status of girlfriend,live in girlfriend,fiance,or wife.
