Based on this and this answers.

LanguageListener.php:

session = $session;
    }

    public function setLocale(GetResponseEvent $event)
    {
        if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
            return;
        }

        $request = $event->getRequest();
        $request->setLocale($request->getPreferredLanguage(array('en', 'de')));

    }
}

services.yml:

acme.language.kernel_request_listener:
    class: Acme\UserBundle\EventListener\LanguageListener
    tags:
        - { name: kernel.event_listener, event: kernel.request, method: setLocale }

About wrong locale detection in twig, there could be a lot of different causes. Search through the SO, you'll definitely find the answer. Make sure that your '_local' var is defined right, make sure that you put your languages files in the right place, etc. FInally, read again the last version of the documentation: http://symfony.com/doc/current/book/translation.html
