A free app for Android, by Absokotlic.
This application will not only protect your smartphone against theft, but also will make you aware of any attempt by someone to unlock it without your permission. This is because the application is set to be triggered when the phone is moved or when someone tries to open the lock.
The app is designed in such a way that it will only begin to work when the phone is placed on a secure surface. This way, even if someone tries to open the phone, it will not work because the phone is not in a position where it can be unlocked.
You can also set the time for the app to begin working. This is useful, because if you are in a location where you cannot hear the alarm, you will still be able to see the photo of the person who triggered it.
