#5 Aim Assist/ Peek and Fire
If you're playing on a touchscreen phone, aiming becomes quite a headache. Therefore, enabling Aim Assist can help you target the body of the enemies. It is also a helpful trick for sniping. In the early stages of playing PUBG Mobile, enabling Aim Assist will only work in the favor of the player.
Peek and Fire is also a very helpful tool when playing against a squad. This option helps you to prevent exposing your full body while shooting, probably allowing you to reduce the damage you take to the body, while managing to scope opponents out.
