Need help

NDK13

Got a new phone because the game was very bad in my old phone and the device was over 2 yrs old. New phone is mi note 5. I can't parry or evade, there's constant lag along with taking atleast a minute to load and sometimes the champs are standing still after a 5 hit combo. Need to know if there's anyway to reduce the settings of mcoc at its lowest so that I can start playing the game properly any help would be appreciated. A friend of mine also bought the same phone and has the same problem as well.
