I flashed the latest 1.52.3 version on my ESP32-3246S035C, and in LANDSCAPE mode,
The touch coordinates matched the screen coordinates without using a touch.init command.

The GUI buttons also worked correctly.

I changed it to LANDSCAPE REVERSED mode and touch was not correct until I added a TOUCH.INIT 0
command to the start of my test program.

PORTRAIT mode worked correctly for screen coordinates and GUI with TOUCH.INIT 1 at the start of the program.

PORTRAIT REVERSED mode did not work correctly with any of the TOUCH.INIT values 0 to 3.

Ok, thanks.
Could you try the version 1.52.4 and let me know if this fixed the PORTRAIT REVERSED (should be touch.init 3)?

I flashed version 1.52.4 on my ESP32-3248S035C module.

LANDSCAPE mode works properly either with no TOUCH.INIT command or with TOUCH.INIT 2 .

LANDSCAPE REVERSED mode works correctly with TOUCH.INIT 0 .

PORTRAIT mode works correctly with TOUCH.INIT 1 .

PORTRAIT REVERSED mode works correctly with TOUCH.INIT 3 .

Both GUI button performance and coordinate correspondence between TFT and touch were checked.

It all looks very good to me. Thank you again for all your work on this.
