Thank your advice, Yi. I search and reference others articles. Changing the input device mode to 0666, and now touch is work. But the point coordinate isn't right, it always appears on left-upper location. And this method (change the mode to 0666) is also brute force method. Anyone can directly access the input device if they want. So, I have some work needed to do.
Thank you.
