I am having the same problem too. Thought it might be an issue with Windows, so decided to do a fresh install, but had the same issue of random screen presses without me pressing anything during the Windows set up, tried Linux, same issue. I have ended up disabling the touchscreen in Windows. Interestingly the Pen still works, although the registration of pen touching the screen is off. I have tried calibrating it, but it is still out by about a centimetre. I would suggest a hardware failure or an issue in the BIOS. I have reported it to Chuwi via the website, but not yet had a response, as it was a Saturday, I am going to give them until late Tuesday before I chase through Amazon.
