Where to report device-specific bugs to Samsung?

I'm looking for a place to report Android bugs on Samsung devices. The place would ideally have actual representation by Samsung developers. Japanese forums are ok.

I have tried:
- http://innovator.samsungmobile.com - Здесь есть форум Java ME, но на существующие сообщения Android нет ответа.
- http://developer.samsung.com - указывает на то же содержание, что и первая ссылка.
- Calling Samsung 3rd level support to ask for a reference - they told me to use the 1st link but couldn't tell me which forum was appropriate to file bugs against Android devices.
