Overcome mobile Java mouse movement lag

I'm trying to make a mobile Java game simple point and shoot but when I tap the screen to shoot from the right most area to the left most or if it's a significant move then the bullet will not aim in the direction of the crosshair but the last position the crosshair was seen. Has anyone overcome this issue because it's really annoying. It doesn't happen with the Windows EXE or Java build but happens all the time with Java mobile build. I tried using groups but still get the same lag.
