I just received what appears to be a security update for my 8.0" T713.
My current build is now:: NRD90M.T713XXU2BRB2.
I know that the Galaxy Tab S2 has been out for a long time and some have posted that we can no longer expect support or updates from Samsung. But Samsung is still selling the S2 on their website and at retail outlets. And the T713 is still considered to be their premium 8" tablet. IMO, Samsung should provide updates and support for at least one year after they discontinue the model. That is only fair for the latest buyer of a "new" S2. (I have an iPad 3 that received support and updates 3 years after it was discontinued. It is now more than 5 years old and i still use it. My son bought me the latest iPad Air, but i made him return it because the ipad 3 still works well.)
