I can not give permissions to android app, In the developer options menu, there is only USB debugging option is available.
Here are the Command line outputs,
$ pm grant com.draco.resolutionchanger android.permission.WRITE_SECURE_SETTINGS
Exception occurred while executing 'grant':
java.lang.SecurityException: grantRuntimePermission: Neither user 2000 nor current process has android.permission.GRANT_RUNTIME_PERMISSIONS.
