I'm looking for free Android apps (that's without ads) for
a) locking (ie block) users from installing/running apps that
we don't endorse. Smart App Lock free version comes
b) that our Helpdesk can just tap/launch & it'll verify if the
Android tablet is rooted/jail-broken
Ideally the apps recommended will work when the Android
is updated, easy to use & have good user ratings. We are
looking at a Samsung tablet.
