You have chosen Movement as your detection method and turned on the Intruder Detection feature, but nothing happens when your device is moved.
Battery Optimization tools are pre-installed on some devices by the manufacturer. They are designed to put apps to sleep when not in use in order to save battery. If the Intruder Detection feature is not detecting movement then it may have been restricted by one of these tools.
Disable Battery Optimization for the Certo app.
This process varies depending on your device model but on most devices, you can access the battery options for Certo as follows:
- Open your Settings app
- Tap Apps
- Tap Certo
- Tap Battery
