Yep fizzy. Much much better in smoothness and responsiveness. I used to have delayed touch timing issues with 12.0.8.0 - big time. They've been ironed out. Also the 120 refresh is a lot smoother - on the older rom it seemed that it wasn't even using it. Battery seems to be down, although I haven't had it on for 24 hours yet so not sureSerious? I might flash that now lol, I miss BT audio and some MIUI featuresMight go back to stock ROM and just root
