Envision S touchscreen malfunction is due to issues with the screen itself, adhesive from the screen protector sticking to the surface, problems with the resistive screen, and other reasons. The details are as follows: Issues with the screen itself: The screen itself has a problem. If this is the case, it involves many reasons, such as touchscreen damage, loose connections, or loose display wiring, etc. In such situations, it can only be repaired at a 4S shop. Adhesive sticking to the screen surface: There is a screen protector on the screen, causing the adhesive to stick to the surface. Use dishwashing liquid, essential balm, etc., to clean the adhesive off the screen. Problems with the resistive screen: Restart the device. First, locate the restart button, usually on the back or side of the device. Use a paperclip or toothpick to press it and restore the device to its initial state. If there is a response, you can calibrate the screen in the settings, and it should work after calibration.
