Press the "Go to Accessibility Preferences" button and confirm the next query.
Then select the NIMMSTA Scan Service from the "Installed apps" menu that opens.
Before the NIMMSTA Scan Service can be activated, the following query must still be allowed, the status should then change from "Off" to "On".
Depending on the android version, it may not be possible to activate the NIMMSTA Scan Service directly.
In this case, additional steps must be carried out. Go to the "Apps" tab under Settings and select the NIMMSTA app:
Click on the three dots at the top right and click "Allow restricted settings":
The NIMMSTA Scan Service can then be activated:
Press the back button on your Android device several times until you are navigated back to the NIMMSTA APP. The status Enabled is now displayed for the Accessibility Service.
