I have tweaked my Chuwi a lot. Also purchased a real Chuwi keyboard and must say I am very happy with it now. It really, really is a fine laptop. I do not have the issues you are dealing with, how odd. The only recurring issue I have to face is the weird behaviour of battery-life. Last time I mentioned the Chuwi had returned to normal readings of about 10,000 mWh, now I have again only 3345 mWh with 21.4% (of 4,300 mWh) battery wear. I hope it will one day turn back again to normal, but I just keep it connected to current and can work with it, as with any laptop. Only without current it goes downhill very fast and can use it for perhaps three hours (never tried to go to 0 battery level).
The keyboard sometimes misses a character when typing, anyone else notices the same? I have to type with real force now to be sure I have not missed a character. Anyone?
