Now I get that mobile phones are private. And I wouldn't like my DP to snoop through mine. But if he did I am confident he wouldn't find anything. I never change my passcode. It's usually on loud etc.
Is it normal that his:
Is always on quiet.
Has is set so notifications do not come up at all. Not missed calls/texts/whatsapp. (He says this is so he isn't distracted at work)
Changes his password at least every week.
Deletes all call logs/texts etc (says he likes it to be clear. And once a text or whatever is dealt with he deletes it)
Oh and he never answers calls in front of me.
Never shows photos etc.
