Thanks for the Lawnchair tip, I will check it out too. My 40H has worked like clockwork, not a single issue. Only oddity is no Glonass GPS support as per specifications, however it does pick up the Japanese QZSS constellation which does orbit over Australia.
I did update the firmware this week and no issues there either.
I am blown away by the performance / value of this tablet. They just get better and better and you start to question the way higher price of the bigger brands.
