There is some sound distortion when is Mi Sound Enhancer on and when you choose Mi Piston 2 in options. Distortion is present only when u choose Piston 2, not on other headphones. I have Mi3 and this bug was on 6.1.11 too.
Since I have Offical China dev 5.12.17 rom can I instal this 6.1.12 EU with twrp recovery? Also can you give me link how to flash twrp and tell where to copy rom and which wipes to do because i used it long time ago and dont remember. Thanks
