There is actually some issue coming recently with z9 however gaming is great with

Pupg smooth 60fps

Codm smooth 90fps 

Bloodstrike low support 120 drop to even 45fps

Carx drift 2 adaptive 30fps 60fps start phone getting so hot 

Car x Street - 30 fps locked blurry mess

On above games some games like codm still no support for 120 and as for car x u can run at only 30 which so unfortunate because I bought this for 20k and 20k is listed on Amazon .And for 20k price range it also copete with 21-23k phone while it's competitors are getting 7+gen2 we have 7200 and no display chip and new iqoo z9 turbo is launching for only 5k more or so ..

As for issue fps is not stable time to time it fluctuate so quickly (55-60 like that)

Inside the 20k price it should have atleast display chip or something like that I tried looking for alternative apps or methods not a thing unfortunately which is pretty disappointing tho ...
