I have an ATP with ASUS app locker preinstalled.
The locker app is very secure, but is missing a few functions like delayed lock or relock after display sleep.
I tried a few apps from the market, but non has such high security standards like the ASUS app lock. I could trick all apps by switching to the desktop by the desktop icon, and could switch back to a lockked app via the recent apps list.
The ASUS app locker prevents apps from displaying in the recent apps list, but non of the other locker apps did this.
Is there a very good locker app which uses root to ensure a very high security profile?
