Hi there, i got same problem.

I just bought it, and touchscreen some times just doesnt work, i.e. freezes for 30 seconds or 1 min then working again, or i've to restart to get it work properly again. it's annoying. 

btw, the bois chipset, driver is the most updated ones too on mine .

I have noticed, as I encounter this problem only in "tablet-mode", if I flip the screen back into "laptop-mode", the touch function works perfectly again. I find that peculiar, since it may be supposed to be the other way round; the touch function should work when in tablet-mode, but may be turned off when in laptop-mode.  

It appears this is a design fault, because I am suffering the same blight.

Hi

I received my XPS 12 on November 9th and immediately had issues with the touchscreen where it would just completely stop working. After 8 hours of technical support over the phone spanning two days,  they decided to send a technician out to replace the touchscreen.  The technician replaced the screen and the touchscreen hasn't worked since.  They created an exchange 2 weeks ago and it still hasn't shipped out.  

I loved the machine for the few minutes it actually worked but this has been very frustrating experience.  

Obviously there is some type of hardware flaw now that I see more people are reporting similar issues.

same issue here. just randomly stops working. just installed a fresh ver of win8 to to get all the dell preloaded stuff off but still having issue. any rep from dell have any info on this?

I am sorry to read that all of you are having this type of problem.  If you still require help please shoot me a private message.  Just click on the link in my signature and then choose start coversation.  In your message please include the service tag of your notebook and I will be happy to research service options.

I had my screen changed too, they tried twice with two difference technicians and both times the new screen did not work for touch screen.  The last technical gave up and left me with the issue and told me to reinstall windows to fix it but it didn't work.  I have already been rejected for a replacement even though this is a brand new laptop so I have requested to return the laptop instead.  Will hear back next week.  Cannot wait to get rid of this laptop now, as it has wasted so much of my time! on the phone, at work waiting hours for the technicians to fix the problem, who only come during work hours :(
