For various reasons (probably because I'm not a very good parent :-)) I've needed to use applock by Domobile Lab to prevent my 14 yo from
- putting viruses on my android phone from Google Play
- putting games on my android phone from Google Play
- constantly switching skins/settings/features so I have to re-learn the phone to call someone
However she's found an interesting way around this -- we have a flight of laptop computers in the house, with me autologged into my Gmail account on Chrome and she goes to Google Play Apps as me, and sends apps from there to my phone. This circumvents applock completely.
[I do understand I should just lock the computers and that would take care of this]
If she bought stuff, she would have to re-enter my password which she doesn't have, but she can download all the free (and virus containing) apps she likes.
It strikes me this is a bit of a security hole - it's common for people to leave Gmail open and running -- believe me, there's nothing worth reading in my email.
