I Have Samsung Galaxy S duos with Android 4.04 ICS, is it possible upgrade to Jellybean through Auth. service center.

HI naidu_sandra, welcome to the eTI forums. Unfortunately samsung never released any official update for this phone and chances are that they will never do so. However, if you know what is flashing then you can update it yourself , there is KyleOpen ROM which can help you get your phone to latest version and this ROM is known for very little bug and being stable.
