There is a known problem on some devices, especially TV boxes: despite all permissions are granted, Headwind Remote still cannot simulate gestures. Apparently this is caused by a bug in the device-specific Android OS build.
More specifically, the function AccessibilityService.dispatchGesture() reports success, but in fact it doesn't dispatch a gesture.
Headwind Remote requires that an Android SDK on a device should work according to the official documentation. According to our investigations, this issue is caused by a failure of a system method, so apparently nothing could be done with this.
