IDK, are there any capacitive touch screen handheld devices that can be calibrated? My old Palm OS based handhelds had to be calibrated, but they were all resistive touch screens. Because capacitive touch screens use a grid type electrode layout to detect touch location, I wonder if they even need to be calibrated in the first place?
You can't calibrate an iPhone screen, can you (also a capacitive screen). What about other capacitive screens?
