Some spaces not working on H640p

So i have a problem with my device. That on few places, the track/touch pad loses the pen
when it looses the pen it jumps from one place to an other (I found two of these spaces). I drove on the entire workspace. (on photo)

On the photo is seen where are the broken areas. 

On the video how is it broken (in case I didn't explain too well).

  • Hi Bart Kopel, thank you for providing a video and the picture of your issue. Have you installed the driver? If you have, kindly uninstall the driver, unplug your tablet from your computer then plug it back in. Then test if it still happens even without the driver. Kindly test your tablet on a different computer as well, if you have access to another unit and check if your tablet still behaves the same. 

    If it still happens even without the driver and with a different computer, it is possible that your tablet may be defective but we still have to test it further using our QC software. In order to do that, please send an email to with the following information:

    1. Serial number (found at the back of your tablet, right after S/N)
    2. Order number
    3. The video you've just provided. Or you can attach the link to this forum post which is:
    4. An short explanation about your issue and the steps you've tried so far.

    Best Regards,

    HUION Customer Support
