I currently have a Redmi note 10 5G. It has 4gb + 3gb of RAM (RAM extension feature) which is not even that bad.

But still for some reason my system just feels bad in general. Apps just stop working when in background which is really annoying when I need to multitask. I have seen phones with the same ram as mine (less if you the 3gb from memory extension) which just work so much better. And I am begging to think it must be something about MIUI.

Will that get any better once Hyper OS comes around? Or do you think I should just install a custom ROM? If the second option is the best, what should I install now that custom roms are not so popular? Also os there any way to install other OSs? I for example like how Huawei’s Harmony OS looks, is it even possible?
