- Hiding their app icon from launcher, but add a widget that looks the same. So if the user tries to uninstall the app, they just deleted the widget and the app remains.
- One app would install other apps from the same company in the background without user consent.

- Requesting every permission under the sun and transmit as much info to the mothership as possible
- Secretly turning on the camera and film their users
