Redmi Note 4 snapdragon, Mido. Global Stable 220.127.116.11 and 18.104.22.168, root I disabled noise cancellation in system/build.prop, because often the caller or called person didn't hear me. After disabled noise cancellation this problem is solved. Earlier disabled VoLTE and OK Google, but not solved. Original: Code:##fluencetype can be "fluence" or "fluencepro" or "none" ro.qc.sdk.audio.fluencetype=fluence persist.audio.fluence.voicecall=true persist.audio.fluence.voicerec=true persist.audio.fluence.speaker=true Finally replace to (but i tried any other variations) Code:##fluencetype can be "fluence" or "fluencepro" or "none" ro.qc.sdk.audio.fluencetype=none persist.audio.fluence.voicecall=false persist.audio.fluence.voicerec=false persist.audio.fluence.speaker=false So, after i did this, the loudspeaker volume very low (in max volume) (just in-call loudspeaker, media, etc is normal volume). I tried modifiy in system/etc/mixer_paths.xml files the speaker and other sections, but nothing to change. I have lot of mixer_paths_(*).xml files (SEE THIS PICTURE), but i don't know which is in use. How can I solve it? Thanks!
