手机端上Django i18n无法使用？

Question

大家好，我最近在做一个网站，使用了i18n来帮助实现中英文切换，目前在电脑端上切换中英文已经没有任何问题，可是在手机端上切换时却完全无效，请问大家一下原因可能是什么呢？

urls.py: 
urlpatterns = [
    url(r'^i18n/', include('django.conf.urls.i18n')),
    ...
]

----------------------------------------------------------------------------------

settings.py
MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

LANGUAGES = [
    ('en-us', _('English')),
    ('zh-hans', _('Chinese')),
]

LOCALE_PATHS = (
    os.path.join(BASE_DIR, 'conf/locale'),
)

base.html
<form action="/i18n/setlang/" method="post">
    {% csrf_token %}
    <button type="submit" name="language" value="en" class="language_switcher">ENG</button> 
    / 
    <button type="submit" name="language" value="zh-hans" class="language_switcher">中文</button>
</form>

谢谢大家！

你是通过什么设置来实现语言切换的？比如：在session里设置LANGUAGE_SESSION_KEY？或者是HTTP请求头部里的Accept-Language？
我是通过前者来实现的，手机测试没有问题。（django1.9.8）

from django.utils import translation
if 想用英文:
    user_language = 'en'
else:
    user_language = 'zh-Hans'
translation.activate(user_language)
request.session[translation.LANGUAGE_SESSION_KEY] = user_language
