Noticed this free app over at HUKD
Intruder Catcher: Lock Screen and App protection by Augustro is a powerful security app. It hides behind your lock screen and if someone tries to unlock your phone with the wrong code, it takes a picture of the person with the front facing camera and immediately emails the photo of the intruder to you. Also it can lock access to your private apps with fingerprint/pin/pattern and can capture intruder selfies at app lock screen too. It has no advertisements.
Enjoy!
Thought this would be a joke app, but thinking on it, this should be a default feature available on Android (or any phone).
