public static boolean hasAccessRestrictedPerm(Context context) {
    try {
        PackageManager packageManager = context.getPackageManager();
        ApplicationInfo applicationInfo = packageManager.getApplicationInfo(context.getPackageName(), 0);
        AppOpsManager appOpsManager = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
        int mode = appOpsManager.checkOpNoThrow("android:access_restricted_settings", applicationInfo.uid, applicationInfo.packageName);
        return (mode == AppOpsManager.MODE_ALLOWED);
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}
