Why has the 2016 flagship tablet been abandoned on android 7 nougat and not received android 8? They were launched with android 6 marshmallow being the 2016 version and upgraded to 7, but not 8? Although 9 is out now, why has this tablet only received 1 major update and not 2 as per your standard claim of 2 major updates?
Also, no regular security updates. My T813 is currently still on August 2018!! Whereas my wife's T713 has just updated to January 2019.
Although I am a big Samsung fan I am extremely disappointed with the lack of support for your previous flagship tablets and may be forced to look elsewhere in the future for better backup.
