Here is how someone can bypass Avast Anti-theft lock screen very easy;
Suppose you sent message "1234 LOCK" to your lost phone and screen is locked,
but here is problem, and that is notification bar can be pull down and 4 digit code
can be seen easily,
(Yeah its for very short period but if its pulled down repeatedly then it
is visible very well)
P.S: Please fix this , i really like this app.
