kimmoli, I found how to fix the "Voice Call volume on speakerphone mode does not work". The problem was in CM12.1 .
mount -n -o remount,rw /system
\cp /home/nemo/Downloads/etc/* /system/etc
\cp /home/nemo/Downloads/lib/hw/* /system/lib/h...
Only qt5-plugin-geoservices-Nokia-5.2.1+git3-1.20.3.armv7hl.rpm install so:
devel-su rpm -iv --nodeps package.rpm Thank you, KiRiK!
Thanks, rinigus, kimmoli, mal !!!
1) With camera I am all right from the first (can be because of onyx-4k-video by kimmoli)
2) With a compass too everything is normal.
Thanks for answering!
I did not find the source code :(.
I am glad that you managed to establish "normal call volume ..."! Speakerphone (Speaker+Fix+CM12.1.zip) depends on him.
I have found orginal Speaker+Fix+CM12.1.zip. He is established through twrp-->install.
If you have time, check please on basic CyanogenMod 12.1-20160201 (on the Android).
The camera works very well on 22.214.171.124. I have rebooted 10 ...
