Galaxy S5 sets the duration of long press to a short delay or 0.5 seconds in default. This will brings you some difficulty for doing some functions.

But if you observe more inside Galaxy S5, you can see that it has an accessibility feature named Press and Hold Delay which will help you set the recognition time for long press as well as delay. By this setting, you can control/set time the device should delay before opening any functions/actions.
