I just fought with this display from Sainsmart for abit, found you need the latest librarys.
Electronics - Henning Karlsen for touch
Electronics - Henning Karlsen for display
works well.
Id say those 3.2 screens arnt the best for touch, but the display is great. For the price, I can live with the touch not working to great. I'm thinking if I keep all the buttons on the more accurate side, I should be good.
