After installing the KOASON Android screen, normally you can return to the Android interface by touching the screen in the original interface. However, some customers cannot return to the Android interface by touching the screen surface after installing the screen because the "Touch data continuously sent" option is selected in the Android factory mode. You need to enter the Android factory mode to cancel this option.

1.1. Press and hold the screen for 2 seconds to return to the Android interface.
