A nice side effect of that was I could clearly control when the phone won't even be on me and I had set that expectation - like treks, or short personal vacations, sleeping hours (yes!). I had championed the "follow the sun" policy in my company when it came to on-call rotation, but somehow some of my fellow country men/women colleagues took pride in "being available". Anyway, their time, their choice.
Later some of my colleagues were surprised when they couldn't install certain apps, couldn't do certain things and often used to wonder "does the company take screenshots of my phone?" because the permission was present :D
