Purchased a PiPo X15 which came with a signed goodix driver for the touchscreen, version 220.127.116.1110_20210913.
We are testing this as a POS unit before purchasing a few more.
The screen is unresponsive and does not always accurately press in the location we are pressing. I'm not sure if this is hardware fault or simply a old driver that has a bug .
Here is a video of the problem where you can see that sometimes they press in one location but the tap is indicated in another location as well as having to press the screen multiple times to trigger input.
