Just as an update to this. My Vi10 Plus was freezing constantly on Remix OS. I wiped it, flashed a new BIOS for Windows, then installed Windows 10. It has worked flawlessly and has not frozen once, and the keyboard no longer wakes the machine either. Very pleased now, but it was a shame that Android never worked well.
I do agree with you about Windows, it solves the problem. But in my case, I want an Android tablet, not Windows. So it’s not a solution. I still hope Chuwi will give a solution…
