Hi Im not able to calibrate the touchscreen and operate it since the touchscreen is not responding as well in the calibration area ( function Shift+4+0 ) Don´t know what to do yet and im thinking about to upgrade the Package version from V1.21 to V4.30 so im asking if this a safe procedure ( jumping so many versions ) or i will update to an unstable firmware ir is there another effective procedure to fix this problem? Please kindly advice, thank you.
