• Instead, The screen issue can be solved by: designing a touch event for a base dpi(dots per inch); setting up a custom touch handler class to get the device screen density, for example: 160 dpi return 1, 480 return 1.5, using a formula similar to pixel = (int)(pixel*density) when taking the touch point, getting the XY coordinate exactly.
