Game play issue
Why can't it run on 120hz even tho my phone able to run at 120hz but on game it's stuck on 60hz not 90hz but 60hz and why can't I change the graphics settings but only stuck at medium (my phone spec is itel rs4 ultra [8gb 128gb version].) while my friend with older phone can go to max settings while I can't do it since it's stuck on medium
Your phone is low budget/tier, which is fine, you get what you get, but you need to have realistic expectations when it comes to optimisation of a niche/budget brand with a heavily customised Android-based OS.
That 8GB RAM is a marketing gimmick because the CPU and GPU are massive bottlenecks. It’s never going to actually push 120Hz in FCM, even on a basic 720p screen you got. The hardware just isn't there.
To compare, my old 6 YO Samsung S20Ultra that I use for MM autoplay, is still twice as fast, a phone that I bought in 2020, so yeah...
