On Topic, I did have this issue.
To fix it you need to remove your google accounts under “Accounts”
Reboot the tablet
Add your google account under “Accounts”
and hopefully it works now.
If it doesn’t repeat the steps, and before you restart, go to settings > applications and see if the playstore app has any updates on it.
If there are any updates remove them, restart and readd your account.
This seemed to work for me.
I haven’t had a chance to thrash my tablet yet, I have found it is very dicky when i power it on, it stays on the battery screen and turns off.
after the 3rd attempt it seems to start OK? anyone else seen this one?
Apart from that i think i have won the Teclast lottery.
I will be doing the power mods tonight, and when my shim and IR thermometer rocks up.
Does anyone use a case with theirs? I am going to install a copper plate in my case to line up with the thermal mod, this should help the tablet run when fitted in a case.
I can also mount the tablet to some magnets in the kitchen so win / win 😀
