Hello,

1.Make sure the dts configuration is correct, you can use adb shell getevent -lt /dev/input/eventX to verify raw touch coordinates.

2.Check the tsc2007.idc file in rootfs, please refer https://source.android.com/docs/core/interaction/input/input-device-configuration-files and https://source.android.com/docs/core/interaction/input/touch-devices#touch-device-configuration

The row value of the driver of the touch is constant depending on the location,
In the app, touch values vary depending on the cursor

In addition to that
If the cursor comes out and comes out, and if you touch the panel from a distance and move it
The cursor moves at that distance.
If you touch the panel near the cursor and move it, it will be displayed close.
