Good game good graphics but very bad in match making

This game is dam hard I feel after win a match the next match aim asist not working like previous match , bullet registration not working properly sometimes I like to play fov at 70-75 as default given to my device ,but sometimes bullet registration not working please make sure it and fix this issue as I experienced in game . And one more thing the control set 3 in which all button are fixed as mentioned in game but scope is also should  fixed if I set it to right hand side but it moves I like to use hold to scope and it move and my aim is not working properly due to scope hold it moves as my finger move little bit right left you understand what I am saying fix this

Game is nice ... But there is no settings for change graphics, sensitivity, controlls etc .... Can't control gun recoil . Overall good game but need to improve.....
