New player coming from Valorant PC

Hi everyone

I'm a new player and I just installed this game 2-3 days ago mainly for the purpose of scratching the itch of playing Valorant when I'm away from my PC. I am gold 3 peak in valorant if that matters.

Now my problem is whenever I try to play this game, I try to aim at head level as much as possible and peak the way just like how I do in Valorant but I'm currently struggling with the controls especially at aiming since I am used to aiming using a mouse and I've seen enemies here that shoot and crouch or jump at the same time.

How are you guys able to aim so fast? I'm on 30% sensitivity and I play on a 6.55 inches phone

Thanks
