what button is l3 on ps4 controller

The L3 button on the PS4 controller is located below the directional buttons and to the left of the left thumbstick. It is actually the left thumbstick itself, which can be pressed down like a button. When you press it, you should hear a clicking sound, which signifies that the button was pushed successfully. The L3 button is activated in the same way as the R3 button, but with the left thumbstick instead of the right. To use the L3 button, press down on the left thumbstick or analog stick. Your character will start sprinting or will perform a special action depending on the game.
