My chuwi touch definitively death! Now i can use it for about 5 minutes and than become crazy! I opened the tablet, check the cable and it appears good. Chuwi suport doesn’t reply to my e-mail, gearbest refunds me only 15$, so the only one solution is purchase a bluetooth keyboard with trackpad, unistall the touch driver and use the tablet as netbook. Very terrible experience with chuwi, i think i prefer buy a classic asus zenpad 10, spend about the same and have a very powerful support to asus.
