How cool would that be to kill your enemy with an exploding grenade at the moment it touches him, or to cook a grenade? Cooking a grenade is the common phrase used to describe this technique. In PUBG Mobile, you can do that by tabbing and holding the fire button that should generate a small timer in the center of the screen. The timer shows you how much you have before the grenade explodes. Now you can evaluate the situation and blow the foe accurately and fabulously.
