Hi, I bought my teclast on gearbest in June 2019. I have the same problem with the 6 and then 9. I contacted gearbest and they told me to send the PC to them at my expense to have it checked, while teclast never answered me.
I only noticed one thing that may be useful. During the first intel driver update there was an incompatibility problem with the video card driver. From that moment the problems with the keyboard started. I don’t know if this is a coincidence or not, but every time I update the intel video card drivers the problem returns and then disappears after a few days. Also if I try to disable the keyboard the problem persists so I don’t think it’s a mechanical issue.
It is really absurd that this thing has happened to so many people and if you agree you could organize a class action against teclast to get a refund.
