My daughter in very tech savy and at the same time is starting to take the wrong path as she hits her teen years. I have installed screentime and it let's me remotely view what she view, installs and things like that. But she is smart and figured out a way around that. And she has what seems like to me some google apps that hide messages and IMG in PDF and KLM using email, maps and other apps. I have taken her phone from her but I for the life of me can figure this out. Its like as soon as she logs into an account in android settings it sets it up. And her nexus 5 always has an update ready for download .. While she is still on 4.4 she has always refused to upgrade to 5.1. Anyone know of any apps like this?
