I click the stealth mode and the icon still shows in apps and lets you access it with password but the thief will see it so password doesnt matter if they know its there and will destroy phone ect. The app is not supposed to show at all!
If you see the avast! icon within your app tray after switching Anti-Theft to Stealth Mode, this is completely normal. The item you see in the app tray does not belong to avast! Anti-Theft but to avast! Mobile Security.
Only Anti-Theft goes invisible. The Mobile Security part is intended to stay visible because the nature of the security solution requires communication with the owner.
However, if you only want to use the invisible avast! Anti-Theft part of the suite, you can uninstall avast! Mobile Security and keep using Anti-Theft. This is possible because Free Mobile Security an Anti-Theft are installed as separate modules.
