I’m new to PUBG (been playing for around 2 weeks). Today I found out there’s an “Aim” feature/button in the controls.

I’m a bit confused — what exactly is the use of this feature and when should it be used? Is it necessary to keep it enabled?

I watch many PUBG players on YouTube but I don’t really see this button in their layout, so I’m not sure if I should use it or not.

I also don’t use gyro, and when I turn this feature on, I can’t control it properly.
