Intruder Selfie app makes your phone takes a picture every time you unlock your phone.
You can enable and disable the background service by clicking the button. After you enable it your phone will take a picture everytime you unlock your phone. The picture will be saved in Pictures\iSelfie directory in your phone storage. I use the front camera to take the picture because with front camera you can take a picture of your face or your
friends when they unlock your phone. This app uses 2 permissions: camera and writes to external storage.
This app use Service and BroadcastReceiver.
