I installed HeadWind MDM on a Moto g (8) with Android 9 (Kernel 4.4.146) +.
When I click the volume button, I can access the device's settings.
Is it possible to block?
1. Make sure you're running the full version of the Headwind MDM launcher: https://qa.h-mdm.com/1732/ If you're running open source version, please contact the support to get a trial version.
2. Open the configuration details, select the "Applications" tab, and make sure android.app.settings app is not allowed:
