So, one of my friends bought iqoo neo 10r and we played brawl stars 

I have neo 9 pro rn and with monster mode and high refresh rate the max fps i get is around 120

But his phone, iqoo neo 10r gets 140 fps 

And keep in mind both device's has 144hz display in them.

Kind of dissappointing but still idk if they plan on giving us usable 144hz inside games just like neo 10r.

Below are the pictures,
