Default [Q] help with sensitive screens

Please can anyone help me since I moved to Note3 (from a Note1) I now suffer from a problem that I never had before and that is when I touch an icon to open an app instead of opening the app the screen flicks to the next page(screen).
If I am very positive in touching the app icon this does not happen, but I never had to be so positive with Note1 switching from screen to screen required a bit more than a little wobble on an icon.
Is there a way I can reduce the sensitivity of this screen switching?
