my 3.5'' screen on Raspbian official mirror, but it got incorrect display.
The X-axis and the Y-axis have opposite information.
such as, when i touch right side of the screen, but the cursor appears at the top of the screen.
What can I do to solve this problem?

I'm having this same issue. Is this a hardware issue or a software issue?

This solved my issue: https://github.com/swkim01/waveshare-dtoverlays#touch-calibration

I simply added Option "TransformationMatrix" "0 -1 1 1 0 0 0 0 1" to /etc/X11/xorg.conf.d/99-calibration.conf to rotate touch 90 degrees to the left.
