Call of Duty Mobile offers two control options - simple and advanced. The following guide page provides an overview of both control modes.
Controls are adjusted independently for each play mode. You can also change them at any time in the game. Just check the settings. There you will not only be able to choose one of the available variants, but also to adjust the layout of all elements displayed on the screen.
This controls variant offers automatic shooting. And the screen will not show the button responsible for this function. Instead, shots will be fired as soon as you point the crosshair at a particular opponent.
On the one hand, this option allows for a quick reaction in the event of a direct duel and confrontation. On the other hand, the shot is fired regardless of the distance. If your crosshair encounters a distant target, the attack will start, regardless of whether there is a chance of a hit or not. By the way, you will also lose ammunition.
In this case, you're the one who controls when a shot is fired. A special button appears, which is dedicated to this function. This allows you to decide when to attack your opponent. On the other hand, there is a delay due to your reaction time. There is also a risk that you might accidentally fire a shot while moving or maneuvering the camera.
