I have no idea what controller CTE32HR is. You will have to look up in UTFT.h
It is much clearer to use ILI9481 or whichever is the actual controller.
If your buttons do not touch correctly, run the Calibration sketch. Follow the instructions.
When you have everything working with UTFT, try the TFT_HX8357 library. It has more intuitive GFX methods. It also works much FASTER.
