Hello everyone, i need your help. I tried to install xiaomi.eu stable v12.1.2.0 for Mi 9T and it was very slow and laggy and i had to return to official stable rom. Now i wanted to install latest weekly miui 12.6 i have same issues, phone takes very long time to boot, animations stutter and apps take ages to open, phone is much slower than official rom and sometimes apps freeze and touch is not responsive. I followed official install guide. How to fix this?
