Question:
Why does the touchscreen not work well?
Answer:

Now, we only provide touch screen drivers for Raspbian and Ubuntu Mate. How to install the driver? See:#Method_1._Driver_installation


Question:
Why does the image provided on wiki does not work on my Pi?
Answer:
  • The image provided may differ depending on batches, however, some Images are just available for Pi 2 (or before, but not for Pi 3). In such cases you can download the latest version from Raspberry Pi website and install the driver. See:#Method_1._Driver_installation
  • Make sure the hardware connection is correct and connects fine.
  • Make sure you've written the image to your SD card using the software File:Win32DiskImager.zip rather then just copy and paste.
  • It is strongly recommended to use a stand-alone 5V/3A power adapter, because the USB port of PC might not have enough power to support the Pi and LCD.
