There are several ways to check if your Android device has the Bosspy application installed. This can be done by dialing the code to enter the application. The default code is 123456, however, if this was changed, it won't work and you will need to use a third party application. Malwarebytes is a tool that will scan your device and will provide a detailed result with all the threats on your device, including hidden spying applications like Bosspy.
