Hi,
I am surprised that I did not find any similar post here. I recognized that the Avast Anti Theft home screen lock can be bypassed by simply setting up a second user (with lollipops multi-user capability). Maybe not all features are available (haven't checked this in detail) but I could install Apps etc. while the main user was in 'stolen phone' mode.
How can I prohibit this 'backdoor' (it is more a second wing of the front door :-) )?
Thx Schwoab
