Guys I need some assistance. A while back I switched to Pixel Experience to test out stock android. It was smooth AF, I play my two main games (MLBB and COD Mobile) in the highest allowable settings without any issues. I switched back to MIUI because stock android disabled the option to turn off a single sim at a time. My question is, is there anything I can do to get the performance of pixel experience and similar OSes on MIUI? Like kernels and stuff? Thanks for your time.
