Who Touched My Phone is a security app that lets you keep track of who has been using your smartphone or tablet in the background. The app uses the front camera to monitor the activity and detect anyone using the phone. It will then notify you of who has been using your device and what they have been doing.
The app is very easy to use and requires minimal permissions to function. It does not require any special configuration to work. You do not need to provide your phone number or even your device's serial number.
In order to use the app, you need first to set up the device administrator permission.
