Another change langauge based on browser

[Evonets]

Hello,

 

I have been bussy creating my whmcs website, but now i am looking into changing the langauge based on the browser langauge.
I have the code up and running but there is 1 problem, the Android app isnt functioning anymore.

The hook is breaking the /includes/api.php end-point with a redirect loop adding language=english to the URL.
Does anyone have the correct hook?

 

<?php

add_hook('ClientAreaPage', 1, switch_language($vars));

function switch_language($vars) {
 
$country_to_language = array(
'default' => 'english',
'AR' => 'arabic',
'AR-DZ' => 'arabic',
