  1. Hi,
    Thanks for the info. It worked all fine to update my Galaxy Tab S 10.5 (wifi) to Marshmallow. However, I tought I would get the TouchWiz 6.0 version with this installation of Marshmallow. After the installation, my tablet still has the TouchWiz 5.0 version. Is it possible to update to TouchWiz 6.0?
