READ_CONTACTS permission is not working unless i manually turn it off & on on android SDK 23+

Question

I am working on an application where I need a user contact picture to be shown if available.

Below is the code for asking read_contacts permission:

  public void requestPermissionOrShowRationale(Permission permission) {
    if (ActivityCompat.shouldShowRequestPermissionRationale(this, permission.permission)) {
        PermissionRationaleDialogFragment dialogFragment =
                PermissionRationaleDialogFragment.newInstance(permission);

        dialogFragment.show(getSupportFragmentManager(), FRAGMENT_TAG_RATIONALE);
    } else {
        requestPermission(permission);
    }
}

public void requestPermission(Permission permission) {
    Timber.i("Requesting permission: " + permission.permission);
    ActivityCompat.requestPermissions(this, new String[] { permission.permission }, permission.requestCode);
}

   public enum Permission {
         READ_CONTACTS(
            Manifest.permission.READ_CONTACTS,
            PERMISSIONS_REQUEST_READ_CONTACTS,
            R.string.permission_contacts_rationale_title,
            R.string.permission_contacts_rationale_message
    ),
    WRITE_CONTACTS(
            Manifest.permission.WRITE_CONTACTS,
            PERMISSIONS_REQUEST_WRITE_CONTACTS,
            R.string.permission_contacts_rationale_title,
            R.string.permission_contacts_rationale_message
    );

& permission call from the activity as below:

  private void checkAndRequestPermissions() {
    if (!hasPermission(Permission.READ_CONTACTS)) {
        requestPermissionOrShowRationale(Permission.READ_CONTACTS);
    }
}

Everything is working fine when I am using targetsdk 23. after changing targetsdk to 26 or up the permission doesn't work. unless I manually turn it off & on from the app permission settings to get the contacts.

Super easy and best solution i have found for my question is TedPermission https://github.com/ParkSangGwon/TedPermission

I have removed all the existing codes for the permission and used the below magic code :)

  setLayout(R.layout.welcome);
    TedPermission.with(this)
            .setPermissionListener(permissionlistener)
            .setPermissions(Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS)
            .setDeniedMessage("This permission is required to show Contact Pictures and Email Address Suggestions.\n\nPlease turn on this permissions at [Setting] > [Permission]")
            .check();

   PermissionListener permissionlistener = new PermissionListener() {
    @Override
    public void onPermissionGranted() {


        }

    }

    @Override
    public void onPermissionDenied(ArrayList<String> deniedPermissions) {
        Toast.makeText(WelcomeMessage.this, "Permission Denied\n" + deniedPermissions.toString(), Toast.LENGTH_SHORT).show();
    }
};
