Lockscreen Observer
  • The app takes pictures with your phone’s front camera whenever a false access PIN code has just been entered
  • Also determines the (GPS) location if a picture is taken
  • Send photos and the location via email or simply store this data on your phone
  • Set the number of failed access attempts after which a picture is being taken
  • Display notification in the status bar whenever a new photo is available
  • Our widget will inform you as soon as a new photo is available
  • App reacts to false entry of either PIN code, pattern or even your phone’s finger-print sensor!

Take a picture when the correct PIN code is entered

It is also possible to have Lockscreen Observer take a picture when the correct PIN code has been entered. So, should someone have found out the correct PIN code after various failed attempts, then you’ll be notified and get a picture.
