The way Who Touched My Phone? works is pretty simple. First, you'll have to grant the app the permissions it needs. In fact, the app also requires a list of the other apps you have installed on your smartphone.
Every time someone tries to access your smartphone, Who Touched My Phone? creates a report with information about the apps you have open. The smartphone's camera is also used to take a photo of the individual in question. That way, you can clearly see the face of anyone who tries to access your information, and you'll even be notified when someone tries to enter your lock screen pattern a few times in a row.
Who Touched My Phone? is a simple app that does what it promises. With it, you can easily identify anyone who tries to break into your smartphone. If you want to keep your smartphone safe from third parties, this app is a great way to do so.
