Thanks for the reply .. I asked on XDA and got a reply that knock off is not present in miui roms .. And he adviced to use MSW tools and install double tap to sleepthe knock off / on function is managed by the G2 kernel ... The kernel miui Rom wears is different as stock roms lg. AOSP kernels are adapted to enable the full knock function, but i don't know if it's the case for Miui Rom...
