I have a HXD8357D display, I am using the spi interface and it's working great. I just started to add in the touch screen portion of the display. I have wired it per the examples and run the touch screen example code "breakouttouchpaint"
This loads and runs just fine, I find the touch screen is not consistently reading in the touch.
I can get it to paint some times and others it skips more of the dots or doesn't paint at all. I have found if I hold the panel tightly by the sides and not the mounting ends I normally get better results and t would function as I expected.
I am thinking the touch portion of the display could be damaged or not installed properly. I am open to idea's.
Thanks
Ron

Could you post the product numbers for the parts you have and some pictures of the connections?
